Introducing Cisco Small Business Analog
Telephone Adapters

This guide describes the administration and use of Cisco Small Business analog
telephone adapters (ATAs). These ATA devices are a key element in the end-toend IP Telephony solution. An ATA device provides user access to Internet phone
services through one or more standard telephone RJ-11 phone ports using
standard analog telephone equipment. The ATA device connects to a wide area IP
network, such as the Internet, through a broadband (DSL or cable) modem or
router.

Introducing Cisco Small Business Analog Telephone Adapters
Comparison of ATA Devices

Comparison of ATA Devices
Each ATA device is an intelligent low-density Voice over IP (VoIP) gateway that
enables carrier-class residential and business IP Telephony services delivered
over broadband or high-speed Internet connections. An ATA device maintains the
state of each call it terminates and makes the proper reaction to user input events
(such as on/off hook or hook flash). The ATA devices use the Session Initiation
Protocol (SIP) open standard so there is little or no involvement by a “middle-man”
server or media gateway controller. SIP allows interoperation with all ITSPs that
support SIP.
The following table summarizes the ports and features provided by the ATA
devices described in this document.

NOTE The information contained in this guide is not a warranty from Cisco. Customers

planning to use ATA devices in a VoIP service deployment are advised to test all
functionality they plan to support before putting the ATA device in service. By
implementing ATA devices with the SIP protocol, intelligent endpoints at the edges
of a network perform the bulk of the call processing. This allows the deployment of
a large network with thousands of subscribers without complicated, expensive
servers.
The following figure illustrates how the different ATA devices provide voice
connectivity in a VoIP network.

•

The SPA3102 and SPA8000 act as SIP-PSTN gateways. They provide PSTN
connectivity in addition to a single FXS port.

•

The WRP400 and WRTP54G routers provide ports for analog telephone
devices and provide QoS in the form of priority packet queueing.

Introducing Cisco Small Business Analog Telephone Adapters
ATA Connectivity Requirements

ATA Connectivity Requirements
An ATA device can be connected to a local router, or directly to the Internet. Each
phone connected to an RJ-11 (analog) port on the ATA device connects to other
devices through SIP, which is transmitted over the IP network.
In order to ensure connectivity between the devices connected to its FXS ports,
the ATA device requires the following functionality to be supplied on the network
connected to its Ethernet port:

•

Connection to an IP router with hairpinning support

•

Connection to an outbound Proxy server

When a phone connected to the ATA device communicates with another phone, it
sends a SIP packet onto the internal LAN. The packet is then forwarded to the
external LAN or directly to the Internet. The source address and source port on the
original packet are assigned by the ATA device DHCP server. The address and
port are translated by the ATA device using Network Address Translation (NAT)
and Port Address Translation (PAT). The packet is then routed back to the internal
network on the ATA device by the local router or the ISP router.
Problems can occur with calls between phones connected to the ATA device
when an outbound proxy or a router with hairpinning support is not available. The
ATA device cannot directly connect the two telephone devices, but requires a
local or remote router to route the packet back to its destination on the local
network from which it originated.
The necessary routing can be provided by a router with hairpinning support, or by
an outbound SIP proxy, which is typically provided by the Internet Telephony
Service Provider (ITSP). When relying on the ITSP for interconnecting phones on
the ATA device, local phones connected to the ATA device are unable to
communicate with each other if the Internet connection is not available for any
reason. It is recommended you connect the ATA device to a local router that
provides hairpinning support to prevent this problem.

•

The IVR functions are accessed by connecting an analog telephone to Line 1.

•

For proper operation, the service provider should use an Outbound Proxy to
forward all voice traffic when the PAP2T is located behind a router. If
necessary, explicit port ranges can be specified for SIP and RTP.

By default, the device attached to the LAN port is assigned the network address
192.168.0.0 with a subnet mask of 255.255.255.0. If there is a network address
conflict with a device on the Ethernet port, the network address of the device on
the LAN port is automatically changed to 192.168.1.0.

NOTE

ATA Administration Guide

•

The IVR functions are accessed by connecting an analog telephone to Line 1.

•

For proper operation, the service provider should use an Outbound Proxy to
forward all voice traffic when the SPA2102 is located behind a router. If
necessary, explicit port ranges can be specified for SIP and RTP.

•

The SPA8000 is not designed to forward IP packets to devices connected to its
AUX port and that configuration is not supported.

•

The SPA8000 also can be configured with trunk groups and trunk lines. See
“SIP Trunking and Hunt Groups on the SPA8000,” on page 77.

ATA Software Features
The ATA device is a full featured, fully programmable phone adapter that can be
custom provisioned within a wide range of configuration parameters. This section
contains a high-level overview of features to provide a basic understanding of the
feature breadth and capabilities of the ATA device.
The following sections describe the factors that contribute to voice quality:

•

“Voice Supported Codecs,” on page 25

•

“SIP Proxy Redundancy,” on page 27

•

“Other ATA Software Features,” on page 27

Voice Supported Codecs
Negotiation of the optimal voice codec sometimes depends on the ability of the
ATA device to match a codec name with the codec used by the far-end device.
The ATA device allows the network administrator to individually name the various
codecs that are supported so that the ATA device can successfully negotiate the
codec with the far-end equipment. The administrator can select which low-bit-rate

ATA Administration Guide

Introducing Cisco Small Business Analog Telephone Adapters
ATA Software Features

codec is to be used for each line. G.711a and G.711u are always enabled.
Configure your preferred codec in the (FXS) tab in the Administration Web Server.
See “ATA Voice Field Reference,” on page121. See also “Supported Codecs,” on
page 54 for a list of which codecs are supported on each ATA device.

Codec (Voice Compression
Algorithm)

Description

G.711 (A-law and mμ-law)

This very low complexity codec supports
uncompressed 64 kbps digitized voice transmission at
one through ten 5 ms voice frames per packet. This
codec provides the highest voice quality and uses the
most bandwidth of any of the available codecs.

G.726

This low complexity codec supports compressed 16,
24, 32, and 40 kbps digitized voice transmission at one
through ten 10 ms voice frames per packet. This codec
provides high voice quality.

G.729a

The ITU G.729 voice coding algorithm is used to
compress digitized speech. Cisco supports G.729.
G.729a is a reduced complexity version of G.729. It
requires about half the processing power to code
G.729. The G.729 and G.729a bit streams are
compatible and interoperable, but not identical.

G.723.1

The ATA device supports the use of ITU G.723.1 audio
codec at 6.4 kbps. Up to two channels of G.723.1 can be
used simultaneously. For example, Line 1 and Line 2 can
be using G.723.1 simultaneously, or Line 1 or Line 2 can
initiate a three-way conference with both call legs using
G.723.1.

NOTE: The WRP400 device does not support the
G.723.1 audio codec.

NOTE When no static payload value is assigned per RFC 1890, the ATA device can

support dynamic payloads for G.726.

ATA Software Features

SIP Proxy Redundancy
In typical commercial IP Telephony deployments, all calls are established through
a SIP proxy server. An average SIP proxy server may handle thousands of
subscribers. It is important that a backup server be available so that an active
server can be temporarily switched out for maintenance. The ATA device supports
the use of backup SIP proxy servers (via DNS SRV) so that service disruption
should be nearly eliminated.
A relatively simple way to support proxy redundancy is to configure your DNS
server with a list of SIP proxy addresses. The ATA device can be instructed to
contact a SIP proxy server in a domain named in the SIP message. The ATA device
consults the DNS server to get a list of hosts in the given domain that provides SIP
services. If an entry exists, the DNS server returns an SRV record that contains a
list of SIP proxy servers for the domain, with their host names, priority, listening
ports, and so on. The ATA device tries to contact the list of hosts in the order of
their stated priority.
If the ATA device is currently using a lower priority proxy server, it periodically
probes the higher priority proxy to see whether it is back on line, and switches
back to the higher priority proxy when possible. SIP Proxy Redundancy is
configured in the Line and PSTN Line tabs in the Administration Web Server. See
“ATA Routing Field Reference,” on page111.

ATA Software Features

Feature

Description

Modem and Fax
Pass-Through

•

Modem pass-through mode can be triggered only by
predialing the number set in the Modem Line Toggle Code.
(Set in the Regional tab.)

•

FAX pass-through mode is triggered by a CED/CNG tone or
an NSE event.

•

Echo canceller is automatically disabled for Modem passthrough mode.

•

Echo canceller is disabled for FAX pass-through if the
parameter FAX Disable ECAN (Line 1 or 2 tab) is set to “yes”
for that line (in that case FAX pass-through is the same as
Modem pass-through).

•

Call waiting and silence suppression is automatically
disabled for both FAX and Modem pass-through. In addition,
out-of-band DTMF Tx is disabled during modem or fax passthrough.

Adaptive Jitter
Buffer

The ATA device can buffer incoming voice packets to
minimize out-of-order packet arrival. This process is
known as jitter buffering. The jitter buffer size proactively
adjusts or adapts in size, depending on changing network
conditions.
The ATA device has a Network Jitter Level control setting
for each line of service. The jitter level determines how
aggressively the ATA device tries to shrink the jitter buffer
over time to achieve a lower overall delay. If the jitter level
is higher, it shrinks more gradually. If jitter level is lower, it
shrinks more quickly.
Adaptive Jitter Buffer is configured in the Line and PSTN
Line tabs. See “ATA Voice Field Reference,” on page121.

International Caller
ID Delivery

In addition to support of the Bellcore (FSK) and Swedish/
Danish (DTMF) methods of Caller ID (CID) delivery, ATAs
provide a large subset of ETSI-compliant methods to
support international CID equipment. International CID is
configured in the Line and PSTN Line tabs. See “ATA Voice
Field Reference,” on page121.

Secure Calls

A user (if enabled by service provider or administrator)
has the option to make an outbound call secure in the
sense that the audio packets in both directions are
encrypted. See ”Secure Call Implementation” section on
page 72.

Introducing Cisco Small Business Analog Telephone Adapters
ATA Software Features

ATA Administration Guide

Feature

Description

Adjustable Audio
Frames Per Packet

This feature allows the user to set the number of audio
frames contained in one RTP packet. Packets can be
adjusted to contain from 1–10 audio frames. Increasing the
number of packets decreases the bandwidth utilized, but
it also increases delay and may affect voice quality. See
the RTP Packet Size parameter found in the SIP tab in the
“ATA Voice Field Reference,” on page121.

DTMF

The ATA device may relay DTMF digits as out-of-band
events to preserve the fidelity of the digits. This can
enhance the reliability of DTMF transmission required by
many IVR applications such as dial-up banking and airline
information. DTMF is configured in the DTMF Tx Mode
parameter found in the Line tabs. See the “ATA Voice Field
Reference,” on page121.

Call Progress Tone
Generation

The ATA device has configurable call progress tones. Call
progress tones are generated locally on the ATA device so
an end user is advised of status (such as ringback).
Parameters for each type of tone (for instance a dial tone
played back to an end user) may include frequency and
amplitude of each component, and cadence information.
See the Regional tab in the “ATA Voice Field Reference,”
on page121.

Call Progress Tone
Pass Through

This feature allows the user to hear the call progress tones
(such as ringing) that are generated from the far-end
network. See the Regional tab in the “ATA Voice Field
Reference,” on page121.

Echo Cancellation

Impedance mismatch between the telephone and the IP
Telephony gateway phone port can lead to near-end echo.
The ATA device has a near-end echo canceller that
compensates for impedance match. The ATA device also
implements an echo suppressor with comfort noise
generator (CNG) so that any residual echo is not
noticeable. Echo Cancellation is configured in the
Regional, Line, and PSTN Line tabs. See “ATA Voice Field
Reference,” on page121.

ATA Software Features

Feature

Description

Signaling Hook
Flash Event

The ATA device can signal hook flash events to the remote
party on a connected call. This feature can be used to
provide advanced mid-call services with third-party-callcontrol. Depending on the features that the service
provider offers using third-party-call-control, the following
ATA features may be disabled to correctly signal a hookflash event to the softswitch:

•
•

Call Waiting Service (parameter call waiting serv set in the
Line tab)
Three Way Conference Service (parameter three-way conf

serv set in the Line tab)

•

Three Way Call Service (parameter three-way call serv set
in the Line tab)

You can configure the length of time allowed for detection
of a hook flash using the Hook Flash Timer parameter on
the Regional tab of the administration web server. See
“ATA Voice Field Reference,” on page121.
Configurable Dial
Plan with Interdigit
Timers

The ATA device has three configurable interdigit timers:
Initial timeout (T)—Signals that the handset is off the hook
and that no digit has been pressed yet.
Long timeout (L)—Signals the end of a dial string; that is,
no more digits are expected.
Short timeout (S)—Used between digits; that is after a
digit is pressed a short timeout prevents the digit from
being recognized a second time.
See “Configuring Dial Plans,” on page 61 for more
information.

Polarity Control

ATA Administration Guide

The ATA device allows the polarity to be set when a call is
connected and when a call is disconnected. This feature is
required to support some pay phone system and
answering machines. Polarity Control is configured in the
Line and PSTN Line tabs. See “ATA Voice Field Reference,”
on page121.

Introducing Cisco Small Business Analog Telephone Adapters
ATA Software Features

ATA Administration Guide

Feature

Description

Calling Party
Control

Calling Party Control (CPC) signals to the called party
equipment that the calling party has hung up during a
connected call by removing the voltage between the tip
and ring momentarily. This feature is useful for autoanswer equipment, which then knows when to disengage.
CPC is configured in the Regional, Line, and PSTN Line
tabs. See “ATA Voice Field Reference,” on page121.

Report Generation
and Event Logging

The ATA device reports a variety of status and error
reports to assist service providers to diagnose problems
and evaluate the performance of their services. The
information can be queried by an authorized agent, using
HTTP with digested authentication, for instance. The
information may be organized as an XML page or HTML
page. Report Generation and Event Logging are
configured in the System, Line, and PSTN Line tabs. See
“ATA Voice Field Reference,” on page121.

Syslog and Debug
Server Records

Syslog and Debug Sever Records log more details than
Report Generation and Event Logging. Using the
configuration parameters, the ATA device allows you to
select which type of activity/events should be logged.
Syslog and Debug Server allow the information captured
to be sent to a Syslog Server. Syslog and Debug Server
Records are configured in the System, Line, and PSTN
Line tabs. See “ATA Voice Field Reference,” on page121.

SIP Over TCP

To guarantee state-oriented communications, SPA2102
and SPA3102 devices allow you to choose TCP as the
transport protocol for SIP. This protocol is “guaranteed
delivery”, which assures that lost packets are
retransmitted. TCP also guarantees that the SIP packages
are received in the same order that they were sent. As a
result, TCP overcomes the main disadvantages of UDP. In
addition, for security reasons, most corporate firewalls
block UDP ports. With TCP, new ports do not need to be
opened or packets dropped, because TCP is already in
use for basic activities such as Internet browsing or ecommerce. SIP over TCP is configured in the Line tabs.
See “ATA Voice Field Reference,” on page121.

Introducing Cisco Small Business Analog Telephone Adapters
ATA Software Features

ATA Administration Guide

Feature

Description

SIP Over TLS

SPA2102, SPA3102, and WRP400 devices allow the use
of SIP over Transport Layer Security (TLS). SIP over TLS is
designed to eliminate the possibility of malicious activity
by encrypting the SIP messages of the service provider
and the end user. SIP over TLS relies on the widelydeployed and standardized TLS protocol. SIP Over TLS
encrypts only the signaling messages and not the media.
A separate secure protocol such as Secure Real-Time
Transport Protocol (SRTP) can be used to encrypt voice
packets. SIP over TLS is configured in the SIP Transport
parameter configured in the Line tab(s). See “ATA Voice
Field Reference,” on page121.

Media Loopback

SPA2102, SPA3102, and PAP2T devices allow service
providers to use media loopback to quantitatively and
qualitatively measure the voice quality experienced by the
end user. One device acts as the audio transmitter and
receiver while the other device acts as the audio mirror.
The audio mirror transmits the audio packets that it
receives back to the transmitter/receiver instead of
transmitting the data sampled on its local microphone (IP
phone) or attached analog telephone (ATA-type device).
Media loopback is configured in the User tab. See “ATA
Voice Field Reference,” on page121.

Introducing Cisco Small Business Analog Telephone Adapters
ATA Software Features

Feature

Description

The Register Retry Enhancements feature for SPA2102,
SPA3102, and PAP2T devices adds flexibility to the delay
timers that are activated when the SIP REGISTER of a
device fails. Once a SIP REGISTER failure response code
is sent, a delay timer is selected depending on the type of
registration failure response code. The delay timers can
be one of the following:

•

Reg Retry Random Delay—Random delay range (in
seconds) to add to the Register Retry Intvl parameter when
retrying a SIP REGISTER after a failure. The default is 0,
which disables this feature.

•

Reg Retry Long Random Delay—Random delay range (in
seconds) to add to the Register Retry Long Intvl parameter
when retrying a SIP REGISTER after a failure. The default is
0, which disables this feature.

•

Reg Retry Intvl Cap—The maximum value to cap the
exponential back-off retry delay. The exponential back-off
retry delay starts with the setting found in the Register Retry
Intvl parameter and doubles it on every REGISTER retry after
a failure. In other words, the retry interval after a failure is
always set to the seconds configured in the Register Retry
Intvl parameter. If this feature is enabled, the Reg Retry
Random Delay setting is added on top of the exponential
back-off adjusted delay value. The default value is 0, which
disables the exponential back-off feature.

ATA Administration Guide

Introducing Cisco Small Business Analog Telephone Adapters
ATA Software Features

Feature

Description

DHCP Renewal on
Timeout

SPA2102, SPA3102, and PAP2T voice devices typically
operate in a network where a DHCP server assigns IP
addresses to the devices. Because IP addresses are a
limited resource, the DHCP server periodically renews the
device lease on the IP address. Therefore, if an ATA device
loses its IP address for any reason, or if some other device
on the network is assigned its IP address, the
communication between the SIP proxy and the device is
either severed or degraded.
Whenever an expected SIP response is not received
within a programmable amount of time after the
corresponding SIP command is sent, the DHCP Renewal
on Timeout feature automatically causes the device to
request a renewal of its IP address. If the DHCP server
returns the IP address that it originally assigned to the
device, the ATA device is presumed to be operating
correctly. If it returns a different address, the ATA device
changes its IP address to the new address provided by
the DHCP server. The ATA device then resets, and once
again sends a SIP register request for the DHCP server to
accept.

ATA Administration Guide

Basic Administration and Configuration
Upgrading, Rebooting, and Resyncing Your ATA Device

NOTE If the value of the Upgrade Enable parameter in the Provisioning page is No, you

cannot upgrade the ATA device even if the web page indicates otherwise.
The syntax of the Upgrade URL is as follows:
http://spa-ip-addr/admin/upgrade?[protocol://][server-name[:port]][/
firmware-pathname]

Both HTTP and TFTP are supported for the upgrade operation.
If no protocol is specified, TFTP is assumed. If no server-name is specified, the
host that requests the URL is used as server-name.
If no port specified, the default port of the protocol is used. (69 for TFTP or 80 for
HTTP)
The firmware-pathname is typically the file name of the binary located in a
directory on the TFTP or HTTP server. If no firmware-pathname is specified, /
spa.bin is assumed, as in the following example:
http://192.168.2.217/admin/upgrade?tftp://192.168.2.251/spa.bin

Resync URL
The Resync URL lets you force the ATA device to do a resync to a profile specified
in the URL, which can identify either a TFTP, HTTP, or HTTPS server. The syntax of
the Resync URL is as follows:
http://spa-ip-addr/admin/resync?[[protocol://][server-name[:port]]/profilepathname]

NOTE The SPA resyncs only when it is idle.

If no parameter follows /resync?, the Profile Rule setting from the Provisioning
page is used.
If no protocol is specified, TFTP is assumed. If no server-name is specified, the
host that requests the URL is used as server-name.
If no port is specified, the default port is used (69 for TFTP, 80 for HTTP, and 443
for HTTPS).

The profile-path is the path to the new profile with which to resync, for example:
http://192.168.2.217admin/resync?tftp://192.168.2.251/spaconf.cfg

Reboot URL
The Reboot URL lets you reboot the ATA device. The Reboot URL is as follows:
http://spa-ip-addr/admin/reboot

NOTE The ATA device reboots only when it is idle.

Provisioning Your ATA Device
This section describes the provisioning functionality of the ATA device. This
section includes the following topics:

•

”Provisioning Capabilities” section on page 44

•

”Configuration Profile” section on page 45

For detailed information about provisioning your ATA device, refer to the SPA
Provisioning Guide.

Provisioning Capabilities
The ATA device provides for secure provisioning and remote upgrade.
Provisioning is achieved through configuration profiles transferred to the device
via TFTP, HTTP, or HTTPS. To configure Provisioning, go to Provisioning tab in the
administration web server.
The ATA device can be configured to automatically resync its internal
configuration state to a remote profile periodically and on power up. The
automatic resyncs are controlled by configuring the desired profile URL into the
device.
The ATA device accepts profiles in XML format, or alternatively in a proprietary
binary format, which is generated by a profile compiler tool available from Cisco.
Find the Profiler Compiler for your ATA at http://www.cisco.com/web/partners/
sell/smb/products/voice_and_conferencing.html#~vc_technical_resources.

ATA Administration Guide

Basic Administration and Configuration
Provisioning Your ATA Device

The ATA device supports up to 256-bit symmetric key encryption of profiles. For
the initial transfer of the profile encryption key (initial provisioning stage), the ATA
device can receive a profile from an encrypted channel (HTTPS), or it can resync
to a binary profile generated by the Cisco-supplied profile compiler. In the latter
case, the profile compiler can encrypt the profile specifically for the target ATA
device, without requiring an explicit key exchange.
Remote firmware upgrade is achieved via TFTP or HTTP (firmware upgrades
using HTTPS are not supported). Remote upgrades are controlled by configuring
the desired firmware image URL into the ATA device via a remote profile resync.
For further information about remote provisioning refer to the SPA Provisioning
Guide.

Configuration Profile
The ATA configuration profile can be either an XML file or a binary file with a
proprietary format.
The XML file consists of a series of elements (one per configuration parameter),
encapsulated within the element tags … . The
encapsulated elements specify values for individual parameters. Here is an
example of a valid XML profile:

some secret
Yes

Binary format profiles contain ATA parameter values and user access permissions
for the parameters. By convention, the profile uses the extension .cfg (for example,
spa2102.cfg). The Profile Compiler (SPC) tool compiles a plain-text file containing
parameter-value pairs into a properly formatted and encrypted .cfg file. The SPC
tool is available for the Win32 environment and Linux-i386-elf environment.
Requests for SPC tools compiled on other platforms are evaluated on a case-bycase basis. Please contact your sales representative for further information about
obtaining the SPC tool.
The syntax of the plain-text file accepted by the profile compiler is a series of
parameter-value pairs, with the value in double quotes. Each parameter-value pair
is followed by a semicolon. Here is an example of a valid text source profile for
input to the SPC tool:
Admin_Passwd “some secret”;
Upgrade_Enable “Yes”;

Refer to the SPA Provisioning Guide for further details.

ATA Administration Guide

Basic Administration and Configuration
Provisioning Your ATA Device

The names of parameters in XML profiles can generally be inferred from the ATA
configuration Web pages, by substituting underscores (_) for spaces and other
control characters. Further, to distinguish between Lines 1, 2, 3, and 4,
corresponding parameter names are augmented by the strings _1_, _2_, _3_, and
_4_. For example, Line 1 Proxy is named Proxy_1_ in XML profiles.
Parameters in the case of source text files for the SPC tool are similarly named,
except that to differentiate Line 1, 2, 3, and 4, the appended strings ([1], [2], [3], or
[4]) are used. For example, the Line 1 Proxy is named Proxy[1] in source text
profiles for input to the SPC.

Network Address Translation (NAT) and Voice over IP (VoIP)
NAT is a function that allows multiple devices to share the same public, routable, IP
address to establish connections over the Internet. NAT is present in many
broadband access devices to translate public and private IP addresses. To enable
VoIP to co-exist with NAT, some form of NAT traversal is required.
Some ITSPs provide NAT traversal, but some do not. If your ITSP does not provide
NAT traversal, you have several options.

Configuring Your System for ITSP Interoperability
Network Address Translation (NAT) and Voice over IP (VoIP)

NAT Mapping with Session Border Controller
It is strongly recommended that you choose an ITSP that supports NAT mapping
through a Session Border Controller. With NAT mapping provided by the ITSP, you
have more choices in selecting a router.

NAT Mapping with SIP-ALG Router
If the ITSP network does not provide a Session Border Controller functionality, you
can achieve NAT mapping by using a router that has a SIP ALG (Application Layer
Gateway). The WRV200 router is recommended for this purpose, although any
router with a SIP-ALG can be used. By using a SIP-ALG router, you have more
choices in selecting an ITSP.

Configuring NAT Mapping with a Static IP Address
If the ITSP network does not provide a Session Border Controller functionality, and
if other requirements are met, you can configure NAT mapping to ensure
interoperability with the ITSP.
Requirements:

•

You must have an external (public) IP address that is static.

•

The NAT mechanism used in the router must be symmetric. See “Determining
Whether the Router Uses Symmetric or Asymmetric NAT,” on page 52.

•

The LAN switch must be configured to enable Spanning Tree Protocol and Port
Fast on the ports to which the SPA devices are connected.

NOTE Use NAT mapping only if the ITSP network does not provide a Session Border

Controller functionality.
STEP 1

Connect to the administration web server, and choose Admin access with
Advanced settings.

STEP 2

Click Voice tab > SIP.

Configuring NAT Mapping with STUN
If the ITSP network does not provide a Session Border Controller functionality, and
if other requirements are met, it is possible to use STUN as a mechanism to
discover the NAT mapping. This option is considered a practice of last resort and
should be used only if the other methods are unavailable.
Requirements:

•

STUN is a viable option only if your router uses asymmetric NAT. See
“Determining Whether the Router Uses Symmetric or Asymmetric NAT,” on
page 52.

•

You must have a computer running STUN server software.

•

The LAN switch must be configured to enable Spanning Tree Protocol and Port
Fast on the ports to which the SPA devices are connected.

NOTE Use NAT mapping only if the ITSP network does not provide a Session Border

Controller functionality.

traffic. See “Firewalls and SIP,” on page 53.

ATA Administration Guide

Configuring Your System for ITSP Interoperability
Network Address Translation (NAT) and Voice over IP (VoIP)

Determining Whether the Router Uses Symmetric or
Asymmetric NAT
STUN does not work on routers with symmetric NAT. With symmetric NAT, IP
addresses are mapped from one internal IP address and port to one external,
routable destination IP address and port. If another packet is sent from the same
source IP address and port to a different destination, then a different IP address
and port number combination is used. This method is restrictive because an
external host can send a packet to a particular port on the internal host only if the
internal host first sent a packet from that port to the external host.

NOTE This procedure assumes that a syslog server is configured and is ready to receive

syslog messages.
STEP 1

Make sure you do not have firewall running on your PC that could block the syslog
port (port 514 by default).

STEP 2

Connect to the administration web server, and choose Admin access with
Advanced settings.

STEP 3

To enable debugging, complete the following tasks:
a. Click Voice tab > System.
b. In the Debug Server field, enter the IP address of your syslog server. This
address and port number must be reachable from the SPA9000.
c. From the Debug level drop-down list, choose 3.

STEP 4

To collect information about the type of NAT your router is using, complete the
following tasks:
a. Click Voice tab > SIP.
b. Scroll down to the NAT Support Parameters section.
c. From the STUN Test Enable field, choose yes.

STEP 5

To enable SIP signalling, complete the following task:
a. Click Voice tab > Line N, where N represents the line interface number.
b. In the SIP Settings section, choose full from the SIP Debug Option field.

STEP 6

Click Submit All Changes.

STEP 7

View the syslog messages to determine whether your network uses symmetric
NAT. Look for a warning header in the REGISTER messages, such as Warning: 399
spa "Full Cone NAT Detected.”

Firewalls and SIP
To enable SIP requests and responses to be exchanged with the SIP proxy at the
ITSP, you must ensure that your firewall allows both SIP and RTP unimpeded
access to the Internet.

•

Make sure that the following ports are not blocked:

•

SIP ports—UDP port 5060 through 5063, which are used for the ITSP line
interfaces

•

RTP ports—16384 to 16482

Also disable SPI (Stateful Packet Inspection) if this function exists on your
firewall.

Configuring SIP Timer Values
The default timer values should be adequate in most circumstances. However, you
can adjust the SIP timer values as needed to ensure interoperability with your
ISTP. For example, if SIP requests are returned with an “invalid certificate”
message, you may need to enter a longer SIP T1 retry value.
To view the default settings or to make changes, open the Voice > SIP page, and
scroll down to the SIP Timer Values section. For field descriptions, see ”SIP Timer
Values (sec) section,” on page135 of Appendix B.

Silence Suppression and Comfort Noise Generation

Silence Suppression and Comfort Noise Generation
Voice Activity Detection (VAD) with Silence Suppression is a means of increasing
the number of calls supported by the network by reducing the required bandwidth
for a single call. VAD uses a sophisticated algorithm to distinguish between
speech and non-speech signals. Based on the current and past statistics, the VAD
algorithm decides whether or not speech is present. If the VAD algorithm decides
speech is not present, the silence suppression and comfort noise generation is
activated. This is accomplished by removing and not transmitting the natural
silence that occurs in normal two-way connection. The IP bandwidth is used only
when someone is speaking. During the silent periods of a telephone call, additional
bandwidth is available for other voice calls or data traffic because the silence
packets are not being transmitted across the network.
Comfort Noise Generation provides artificially-generated background white noise
(sounds), designed to reassure callers that their calls are still connected during
silent periods. If Comfort Noise Generation is not used, the caller may think the call
has been disconnected because of the “dead silence” periods created by the VAD
and Silence Suppression feature.
Silence suppression is configured in the Line and PSTN Line tabs. See “ATA
Routing Field Reference,” on page111.

Configuring Dial Plans

Configuring Dial Plans
Dial plans determine how the digits are interpreted and transmitted. They also
determine whether the dialed number is accepted or rejected. You can use a dial
plan to facilitate dialing or to block certain types of calls such as long distance or
international.
This section includes information that you need to understand dial plans, as well as
procedures for configuring your own dial plans. This section includes the following
topics:

Digit Sequences
A dial plan contains a series of digit sequences, separated by the | character. The
entire collection of sequences is enclosed within parentheses. Each digit
sequence within the dial plan consists of a series of elements, which are
individually matched to the keys that the user presses.

NOTE White space is ignored, but may be used for readability.

Use this format to indicate that certain dialed
digits are replaced by other characters when the
sequence is transmitted. The dialed digits can
be zero or more characters.
EXAMPLE 1: <8:1650>xxxxxxx
When the user presses 8 followed by a sevendigit number, the system automatically replaces
the dialed 8 with 1650. If the user dials
85550112, the system transmits 16505550112.
EXAMPLE 2: <:1>xxxxxxxxxx
In this example, no digits are replaced. When the
user enters a 10-digit string of numbers, the
number 1 is added at the beginning of the

Acceptance and Transmission the Dialed Digits
When a user dials a series of digits, each sequence in the dial plan is tested as a
possible match. The matching sequences form a set of candidate digit sequences.
As more digits are entered by the user, the set of candidates diminishes until only
one or none are valid. When a terminating event occurs, the SPA9000 either
accepts the user-dialed sequence and initiates a call, or else rejects the sequence
as invalid. The user hears the reorder (fast busy) tone if the dialed sequence is
invalid.
The following table explains how terminating events are processed.
Terminating Event

Processing

The dialed digits do not match
any sequence in the dial plan.

The number is rejected.

The dialed digits exactly match
one sequence in the dial plan.

•

If the sequence is allowed by the dial plan, the
number is accepted and is transmitted
according to the dial plan.

•

If the sequence is blocked by the dial plan, the
number is rejected.

A timeout occurs.

The user presses the # key or
the dial softkey on the phone
display.

ATA Administration Guide

The number is rejected if the dialed digits are
not matched to a digit sequence in the dial
plan within the time specified by the
applicable interdigit timer.

•

The Interdigit Long Timer applies when the
dialed digits do not match any digit sequence
in the dial plan. The default value is 10
seconds.

•

The Interdigit Short Timer applies when the
dialed digits match one or more candidate
sequences in the dial plan. The default value is
3 seconds.

•

If the sequence is complete and is allowed by
the dial plan, the number is accepted and is
transmitted according to the dial plan.

•

If the sequence is incomplete or is blocked by
the dial plan, the number is rejected.

Dial Plan Timer (Off-Hook Timer)
You can think of the Dial Plan Timer as “the off-hook timer.” This timer starts
counting when the phone goes off hook. If no digits are dialed within the specified
number of seconds, the timer expires and the null entry is evaluated. Unless you
have a special dial plan string to allow a null entry, the call is rejected. The default
value is 5.

Syntax for the Dial Plan Timer
SYNTAX: (Ps<:n> | dial plan )

•

s: The number of seconds; if no number is entered after P, the default timer of 5
seconds applies.

•

n: (optional): The number to transmit automatically when the timer expires; you
can enter an extension number or a DID number. No wildcard characters are
allowed because the number will be transmitted as shown. If you omit the
number substitution, <:n>, then the user hears a reorder (fast busy) tone after
the specified number of seconds.

Examples for the Dial Plan Timer

•

Allow more time for users to start dialing after taking a phone off hook.
EXAMPLE: (P9 | (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx
| 9,8,011xx. | 9,8,xx.|[1-8]xx)
P9 After taking a phone off hook, a user has 9 seconds to begin dialing. If no
digits are pressed within 9 seconds, the user hears a reorder (fast busy) tone.
By setting a longer timer, you allow more time for users to enter the digits.

•

Create a hotline for all sequences on the System Dial Plan
EXAMPLE: (P9<:23> | (9,8<:1408>[2-9]xxxxxx | 9,8,1[29]xxxxxxxxx | 9,8,011xx. | 9,8,xx.|[1-8]xx)
P9<:23> After taking the phone off hook, a user has 9 seconds to begin dialing. If
no digits are pressed within 9 seconds, the call is transmitted automatically to
extension 23.

•

Create a hotline on a line button for an extension
EXAMPLE: ( P0 <:1000>)
With the timer set to 0 seconds, the call is transmitted automatically to the
specified extension when the phone goes off hook. Enter this sequence in the
Phone Dial Plan for Ext 2 or higher on a client station.

Interdigit Long Timer (Incomplete Entry Timer)
You can think of this timer as the “incomplete entry” timer. This timer measures the
interval between dialed digits. It applies as long as the dialed digits do not match
any digit sequences in the dial plan. Unless the user enters another digit within the
specified number of seconds, the entry is evaluated as incomplete, and the call is
rejected. The default value is 10 seconds.

NOTE This section explains how to edit a timer as part of a dial plan. Alternatively, you can

modify the Control Timer that controls the default interdigit timers for all calls. See
“Resetting the Control Timers,” on page 70.

Syntax for the Interdigit Long Timer
SYNTAX: L:s, ( dial plan )

•

s: The number of seconds; if no number is entered after L:, the default timer of
5 seconds applies.

•

Note that the timer sequence appears to the left of the initial parenthesis for the
dial plan.

Example for the Interdigit Long Timer
EXAMPLE: L:15, (9,8<:1408>[2-9]xxxxxx | 9,8,1[2-9]xxxxxxxxx |
9,8,011xx. | 9,8,xx.|[1-8]xx)
L:15, This dial plan allows the user to pause for up to 15 seconds between digits

before the Interdigit Long Timer expires. This setting is especially helpful to users
such as sales people, who are reading the numbers from business cards and other
printed materials while dialing.

Interdigit Short Timer (Complete Entry Timer)
You can think of this timer as the “complete entry” timer. This timer measures the
interval between dialed digits. It applies when the dialed digits match at least one
digit sequence in the dial plan. Unless the user enters another digit within the
specified number of seconds, the entry is evaluated. If it is valid, the call proceeds.
If it is invalid, the call is rejected. The default value is 3 seconds.

Secure Call Implementation

Secure Call Implementation
This section describes secure call implementation with the ATA device . It includes
the following topics:

•

”Enabling Secure Calls” section on page 72

•

”Secure Call Details” section on page 73

•

”Using a Mini-Certificate” section on page 74

•

”Generating a Mini Certificate” section on page 75

NOTE This is an advanced topic meant for experience installers. See also the LVS

Provisioning Guide.

Enabling Secure Calls
A secure call is established in two stages. The first stage is no different from
normal call setup. The second stage starts after the call is established in the
normal way with both sides ready to stream RTP packets.
In the second stage, the two parties exchange information to determine if the
current call can switch over to the secure mode. The information is transported by
base64 encoding embedded in the message body of SIP INFO requests, and
responses using a proprietary format. If the second stage is successful, the ATA
device plays a special Secure Call Indication Tone for a short time to indicate to
both parties that the call is secured and that RTP traffic in both directions is being
encrypted.
If the user has a phone that supports call waiting caller ID (CIDCW) and that
service is enabled, the CID will be updated with the information extracted from the
Mini-Certificate received from the remote party. The Name field of the CID will be
prepended with a ‘$’ symbol. Both parties can verify the name and number to
ensure the identity of the remote party.

ATA Administration Guide

Configuring Voice Services
Secure Call Implementation

The signing agent is implicit and must be the same for all ATAs that communicate
securely with each other. The public key of the signing agent is pre-configured into
the ATA device by the administrator and is used by the ATA device to verify the
Mini-Certificate of its peer. The Mini-Certificate is valid if it has not expired, and it
has a valid signature.
The ATA device can be configured so that, by default, all outbound calls are either
secure or not secure. If secure by default, the user has the option to disable
security when making a call by dialing *19 before dialing the target number. If not
secure by default, the user can make a secure outbound call by dialing *18 before
dialing the target number. However, the user cannot force inbound calls to be
secure or not secure; that depends on whether the caller has security enabled or
not.
The ATA device will not switch to secure mode if the CID of the called party from
its Mini-Certificate does not agree with the user-id used in making the outbound
call. The ATA device performs this check after receiving the Mini-Certificate of the
called party

Secure Call Details
Looking at the second stage of setting up a secure call in greater detail, this stage
can be further divided into two steps.
STEP 1

The caller sends a “Caller Hello” message (base64 encoded and embedded in the
message body of a SIP INFO request) to the called party with the following
information:

•

Message ID (4B)

•

Version and flags (4B)

•

SSRC of the encrypted stream (4B)

•

Mini-Certificate (252B)

Upon receiving the Caller Hello, the called party responds with a Callee Hello
message (base64 encoded and embedded in the message body of a SIP
response to the caller’s INFO request) with similar information, if the Caller Hello
message is valid. The caller then examines the Callee Hello and proceeds to the
next step if the message is valid.

ATA Administration Guide

Configuring Voice Services
Secure Call Implementation

STEP 2

The caller sends the “Caller Final” message to the called party with the following
information:

•

Message ID (4B)

•

Encrypted Master Key (16B or 128b)

•

Encrypted Master Salt (16B or 128b)

Using a Mini-Certificate
The Master Key and Master Salt are encrypted with the public key from the called
party mini-certificate. The Master Key and Master Salt are used by both ends for
deriving session keys to encrypt subsequent RTP packets. The called party then
responds with a Callee Final message (which is an empty message).
The Mini-Certificate (MC) contains the following information:

•

User Name (32B)

•

User ID or Phone Number (16B)

•

Expiration Date (12B)

•

Public Key (512b or 64B)

•

Signature (1024b or 512B)

The MC has a 512-bit public key used for establishing secure calls. The
administrator must provision each subscriber of the secure call service with an
MC and the corresponding 512-bit private key. The MC is signed with a 1024-bit
private key of the service provider, which acts as the CA of the MC. The 1024-bit
public key of the CA signing the MC must also be provisioned for each subscriber.
The CA public key is used to verify the MC received from the other end. If the MC
is invalid, the call will not switch to secure mode. The MC and the 1024-bit CA
public key are concatenated and base64 encoded into the single parameter Mini
Certificate. The 512-bit private key is base64 encoded into the SRTP Private Key
parameter, which should be kept secret, like a password. (Mini Certificate and
SRTP Private Key are configured in the Line tabs.)
Because the secure call establishment relies on exchange of information
embedded in message bodies of SIP INFO requests/responses, the service
provider must ensure that the network infrastructure allows the SIP INFO
messages to pass through with the message body unmodified.

and private keys. Partners can download the Mini Certificate Generator by going
to Cisco Partner Central, Voice & Conferencing page, Technical Resources section.
Use the following URL:

used in the INVITE when making the call, such as “14083331234”. The
maximum length is 16 characters.

•

expire-date is the expiration date of the MC, such as “00:00:00 1/1/34”
(34=2034). Internally the date is encoded as a fixed 12B string: 000000010134

SIP Trunking and Hunt Groups on the SPA8000

SIP Trunking and Hunt Groups on the SPA8000
The SPA8000 supports SIP Trunking, which allows you to connect a traditional
PBX to VoIP services. In this configuration, calls go through the ITSP rather than the
PSTN, yet the call routing functionality is similar to that of traditional PSTN lines.
You can configure up to four trunk groups for the purpose of inbound call routing
and outbound caller identification. You can configure a trunk number on the
SPA8000, such that an incoming call automatically rings the grouped lines
simultaneously or in a specified order. For outbound calls, SIP Trunking ensures
that all calls on a trunk line can be identified by the trunk number and a common
caller ID. This feature helps you to ensure that calls are directed to available lines
and that work groups such as sales teams can work together to answer calls. In
addition, teams can project a common identity when placing outbound calls on a
trunk.
This section provides information about SIP trunking and explains how to
configure your trunk groups.

About SIP Trunking
The SIP Trunking feature allows a traditional PBX to seamlessly migrate from
PSTN service to VoIP service over a broadband link. The SPA8000 offers up to
eight telephone lines to the PBX.

The SPA8000 offers four trunk groups, numbered T1, T2, T3, and T4. A SIP-based
voice service with an ITSP can be configured on each trunk group with a distinct
phone number. Each of the eight SPA8000 lines can be configured either as a
standalone line, as in a classic ATA FXS port, or as a trunk line that is associated
with a trunk group.

ATA Administration Guide

•

Inbound calling: A trunk group offers a single number for callers to call into the
small business, with the capability to programmatically ring one or more trunk
lines.

•

Outbound calling: When a PBX phone makes a call, the PBX selects one of the
available trunk lines. The trunk line assumes the Caller ID of the trunk group.

SIP Path: As a standalone line, the SIP User Agent (SIP UA) exchanges signaling
directly with the ITSP equipment. As a trunk line, the Line UA exchanges
signaling with the internal proxy server only. The Internal Proxy Server handles
all SIP signalling between both ends of the call, from call establishment to
termination.

•

RTP Path: Whether the line is standalone or a member of a trunk group, the Line
UA exchanges RTP packets directly with the ITSP equipment.

Configuring Voice Services
SIP Trunking and Hunt Groups on the SPA8000

NOTE Although the figure shows only one ITSP account, each standalone line and each

Trunk Group can be configured with a different ITSP (with some limitations applied).

Setting the Trunk Group Call Capacity
The ITSP may set a limit to the number of calls that can be made on a trunk group.
You can configure a trunk group’s call capacity parameter to meet the
requirements of the ITSP. Both incoming call and outgoing calls are counted
towards this limit. The call capacity has the following impact on call handling:

•

Inbound calls: When the limit is reached, the Trunk UA replies 486 to the
caller.

•

Outbound calls: When the limit is reached, the Line UA plays a fast busy
tone to the caller. Note that a trunk line can make an outgoing call only
through its own trunk. If that trunk reaches full capacity, it will not attempt to
failover to use other trunks.

You can configure this setting in the Voice tab > Trunk (T1 ... T4) page, Subscriber
Information section, Call Capacity field. For more information, see “Configuring a
Trunk Group,” on page 84.

Inbound Call Routing for a Trunk Group
An incoming call is handled as follows:
STEP 1

When an incoming call is detected by the Trunk UA, the UA first checks if there is
capacity to handle the call. If there is insufficient capacity, the UA rejects the call
with a 486 response.

STEP 2

If there is spare call capacity, the UA consults the Contact List to determine which
line or lines to ring (that is, for the proxy to send SIP INVITE to), and starts “hunting.”
(See “Configuring a Trunk Group,” on page 84)

STEP 3

When a line is selected to ring, one or more PBX phones may be alerted, according
to the PBX features and configuration.

STEP 4

The Caller ID of the external Caller is signaled by the Line UA out to the FXS port
using the configured Caller ID method (FSK, DTMF, etc.). The PBX must be able to
detect Caller ID signal in order for the proper Caller ID to show.

ATA Administration Guide

Configuring Voice Services
SIP Trunking and Hunt Groups on the SPA8000

STEP 5

If the call is picked up by the PBX, the Line UA replies 200 OK with SDP to the
internal Proxy. The Trunk UA in turn replies 200 OK to the ITSP and relay the Line
SDP in the 200 OK message also. If all goes well, the Line UA and the ITSP
equipment start exchanging RTP packets afterwards.

Contact List for a Trunk Group
The hunting process for incoming calls is controlled by the Contact List. The
Contact List specifies the lines to ring, the order in which to ring them, the duration
to ring one line before trying another line, and the maximum period to hunt. Below,
the syntax is described and examples are provided to help you to configure the
Contact List for each trunk group.
SYNTAX: line[,line[,line[…]]],hunt=hrule[,cfwd=target]

•

line: The line numbers (1 - 8), or a wildcard * or ? to represent all lines.

•

The Trunk UA rings only trunk lines, that is, lines that are assigned to a trunk
group through the Voice tab > Line page, Trunk Group field. The Trunk UA
does not ring any standalone lines that are included in the Contact List. The
Trunk UA rings any trunk line that is included in the list, even if it is not
assigned to the particular trunk group for this Contact List.

•

You can instruct the SPA8000 to hunt only the phones that are on-hook,
through the Voice tab > SIP page, Trunking Parameters section, Hunt
Policy field. See “Setting the Hunt Policy,” on page 86.

hunt=hrule: The hunt order, ring interval, and maximum duration, in the
following format: hunt=algo;interval;max

•

ATA Administration Guide

algo: The hunt order.

re: Restart. Hunting starts at the beginning of the list. If the first line does
not answer within the specified interval (see below), the hunt
proceeds through the lines in sequential order.

ne: Next. The Trunk UA determines the line that was chosen in the
previous hunt, and hunting starts with the next line in the list. If that line
does not answer within the specified interval (see below), the hunt
proceeds through the lines in sequential order.

ra: Random order. The Trunk UA randomly chooses a line from the list. If
the selected line does not answer within the specified interval (see

Configuring Voice Services
SIP Trunking and Hunt Groups on the SPA8000

below), the hunt proceeds randomly through the unchosen lines until
each line is tried.

•

al: All. The Trunk UA rings all the lines at the same time.

•

interval: The number of seconds to wait for one line to answer, before
choosing another line. If interval is *, the hunt is stopped at the first line that
starts ringing, and rings the line until it answers, or the caller hangs up, or the
line's ringer times out.

•

max: The maximum duration of the hunt, either in seconds or cycles. When
this limit is reached, the call is rejected or is forwarded to the specified call
forward number (see below).

If max is greater than interval, it represents the total time in seconds
to hunt.

If max is less than interval, it represents the maximum number of
times to cycle through the hunt group. If max is 0, hunting continues
indefinitely until the caller either hangs up or the call is answered.
Exceptions: This value is ignored if algo = all, or interval = * (but
it must be present and should be set to 1).

cfwd=target: If the call is unanswered and the maximum hunting duration
has been met, the call is forwarded to the specified number. When forwarding
the call, the SPA8000 sends a 302 response to the ITSP.

NOTE The call forward settings for the individual lines are ignored during hunting. Instead,

the cfwd settings in the Contact List are used.
EXAMPLES:

ATA Administration Guide

•

1,2,3,4,5,6,7,8,hunt=re;*;1
Lines 1 through 8 are included (1,2,3,4,5,6,7,8). The hunt starts at the
beginning of the list (hunt=re). When an available line is found, the call stays
with the line until the call is either answered, rejected, or cancelled by the caller
(* is entered for interval).

•

?,hunt=al;30;1,cfwd=14085550100
A wildcard character (?) is used to represent “all trunk lines.” All lines ring
simultaneously (hunt=al). If there is no answer after 30 seconds (30), the call
is forwarded to the specified number (cfwd=14085550100).

Configuring Voice Services
SIP Trunking and Hunt Groups on the SPA8000

•

?,hunt=ra;12;1,cfwd=14085550123
A wildcard character is used to represent “all trunk lines.” The Trunk UA
chooses lines in random order (hunt=ra). If a selected line does not answer
within 12 seconds (12), the Trunk UA chooses another line at random. If there is
no answer after 1 cycle (1), the call is forwarded to forwarded to the specified
number (cfwd=14085550123).

•

?,hunt=ra;*;1,cfwd=14085550155
A wildcard character is used to represent “all trunk lines.” The Trunk UA
chooses lines in random order (hunt=ra). The interval is *, meaning the hunt
stops when a selected line starts ringing, and will ring the line until it answers,
or the caller hangs up, or the line's ringer times out. If the ringer times out, the
call is automatically forwarded to the specified number (cfwd=14085550155).

Outgoing Call Routing for a Trunk Group
Outbound calls on a trunk line are handled as follows:
STEP 1

When a PBX phone selects an outside line, the PBX looks for an open line. If the
PBX finds an open line, it takes the line off hook and bridges the audio between
the PBX phone and the line. On detecting the off hook signal, the SPA8000 Line UA
plays dial tone and ready to collect digits from the PBX phone.

STEP 2

As the PBX phone user dials the number, the Line UA applies its dial plan to the
number. If the Line UA detects an invalid number, it rejects the all by playing
reorder tone, then howling tone, then silence. If a valid number is received, it sends
a SIP INVITE message to the internal Proxy.

STEP 3

The Proxy routes the call to the trunk group UA for the line, and the trunk group UA
will attempt to place the call to the ITSP if there is available capacity on the trunk. If
there is no call capacity left on the trunk, the internal Proxy will reject the INVITE
from the Line UA, which in turn terminates the call and plays reorder tone out to the
FXS port.

NOTE The SPA8000 will also apply the Trunk Dial Plan on the number before sending out

INVITE to the ITSP. This Trunk Dial Plan typically is redundant since the trunk should
trust the number sent by the Line UA. By default the trunk dial plan allows any nonempty number: ([*#0-9A-D][*#0-9A-D].)

Additional Notes About Trunk Groups
This section includes information about other topics that may be of interest when
you are configuring trunk groups:

ATA Administration Guide

•

Voice mail: There is no individual mail box for a trunk line. For example, if lines 1,
2, 3, and 4 belong the trunk group T1, then the four lines implicitly share the
same voice mail box from the ITSP. When there is new voice mail waiting in the
trunk mail box, the UAs for all four lines will be notified by the ITSP via the
internal Proxy, and all four lines will show the message waiting indicator, such
as by playing stutter dial tone, if enabled by the administrator.

•

Supplementary features: Supplementary features are offered at the line level
only, not at the trunk level. Via the PBX, the phone user can trigger/control
supplementary service and settings by signaling to the line port or configuring
the line parameters. For more information, refer to the Appendix B, “ATA Voice

Configuring a Streaming Audio Server
This section describes how to use and configure a streaming audio server (SAS). It
includes the following topics:

•

“About the Streaming Audio Server,” on page 90

•

“Configuring the Streaming Audio Server,” on page 92

•

“Using the IVR with an SAS Line,” on page 93

About the Streaming Audio Server
The Streaming Audio Server (SAS) feature lets you attach an audio source to an
FXS port and use it as a streaming audio source device. If the unit has multiple FXS
ports, either or both of the associated lines can be configured as an SAS server.
Use a media signal adapter or “music coupler” to connect an Ethernet cable from a
media source to the FXS port. For example, the MC-9700 Music Coupler has been
tested with ATA devices and is available at the following URL:
www.neogadgets.com/cart/
cart.php?target=product&product_id=17&substring=music+coupler

ATA Administration Guide

Configuring Music on Hold
Configuring a Streaming Audio Server

After you complete the required configuration, the FXS port is ready to stream
audio. The functionality depends on the hook state of the FXS port:

•

If the FXS port is off hook, an incoming call is answered automatically and
audio is streamed to the calling party.

NOTE Each SAS server can maintain up to five simultaneous calls. If the

second line on the unit is disabled, then the SAS line can maintain up
to 10 simultaneous calls. Further incoming calls receive a busy signal
(SIP 486 Response).

•

If the FXS port is on-hook when the incoming call arrives, a SIP 503 response
code is transmitted to indicate “Service Not Available.”

•

If an incoming call is auto-answered, but later the FXS port changes to on-hook,
the call is not terminated but continues to stream silence packets to the caller.

•

The SAS line can be set up to refresh each streaming audio session
periodically using a SIP re-INVITE message, which detects if the connection to
the caller is down. If the caller does not respond to the refresh message, the
SAS line terminates the call so that the streaming resource can be used for
other callers.

Additional information:

ATA Administration Guide

•

The SAS line does not ring for incoming calls even if the attached equipment is
on-hook.

•

If no calls are in session, battery is removed from tip-and-ring of the FXS port.
Some audio source devices have an LED to indicate the battery status. This can
be used as a visual indication as to whether audio streaming is in progress.

•

Call Forwarding, Call Screening, Call Blocking, DND, and Caller-ID Delivery
features are not available on an SAS line.

•

”Sharing One VoIP Account Between the FXS and PSTN Lines” section on
page103

•

”Other Options” section on page104

•

”Call Scenarios” section on page105

Connecting to PSTN and VoIP Services
The SPA3102 has the following ports for connection to telephony devices:

•

FXS port (Phone)—Connect to a standard analog telephone or fax machine,
configured by using the Line page.

•

FXO port (Line)—Connect to a standard telephone wall jack for connectivity to
the PSTN, configured using the PSTN Line page.

Line 1 does not provide a gateway because it provides only VoIP service. The
VoIP-To-PSTN calling function is referred to as a PSTN gateway, and the PSTN-ToVoIP calling function is referred to as a VoIP gateway.
Note the following definitions:

•

ATA Administration Guide

VoIP caller—One who calls the ATA device via VoIP to obtain PSTN service

Configuring the PSTN (FXO) Gateway on the SPA3102
How VoIP-To-PSTN Calls Work

•

VoIP user—VoIP caller that has a user account (user-id and password) on the
ATA device

•

PSTN caller—One who calls the ATA device from the PSTN to obtain VoIP
service

Line 1 can be configured with a regular VoIP account and can be used in the same
way as the Line 1 of any ATA device.
A second VoIP account can be configured to support PSTN gateway calls
exclusively. A different SIP port should be assigned to Line 1 and the PSTN Line.
The same VoIP account may be used for both Line 1 and the PSTN Line if a
different SIP port is assigned to each.
VoIP callers can be authenticated by one of the following methods:

•

No Authentication—All callers are accepted for service.

•

PIN—Caller is prompted to enter a PIN right after the call is answered.

•

HTTP digest—SIP INVITE must contain a valid authorization header.

PSTN callers can be authenticated by one of the following methods:

•

No authentication—All callers are accepted for service.

•

PIN—Caller is prompted to enter a PIN right after the call is answered.

How VoIP-To-PSTN Calls Work
To obtain PSTN services through the SPA3102, the VoIP caller establishes a
connection with the PSTN Line by way of a standard SIP INVITE request
addressed to the PSTN Line. The PSTN Line can be configured to support onestage and two-stage dialing as described in the following sections.

One-Stage Dialing
One-stage dialing allows a call to be started over VoIP and then immediately get a
dial tone on the PSTN.
To use one-stage dialing, the Request-URI of the INVITE to the PSTN Line should
have the form @, where is the
number dialed by the VoIP caller, and is a valid address and port
of the SPA3102, such as 10.0.0.100:5061.

ATA Administration Guide

Configuring the PSTN (FXO) Gateway on the SPA3102
How VoIP-To-PSTN Calls Work

If the FXO port is currently in use (off-hook) or the PSTN line is being used by
another extension, the ATA device replies to the INVITE with a 503 response.
Otherwise, it compares the with the User ID parameter of the
PSTN Line. If they are the same, the ATA device interprets this as a request for
two-stage dialing (see the ”Two-Stage Dialing” section on page 97). If they are
different, the ATA device processes the using the
corresponding .
If dial plan processing fails, the ATA device replies with a 403 response.
Otherwise, it replies with a 200 and at the same time takes the FXO port off hook
and dials the target number returned after processing the dial plan.

NOTE If the User ID parameter on the PSTN Line is blank, the Register parameter should

be disabled for the PSTN Line.
If HTTP Digest Authentication is enabled, the ATA device challenges the INVITE
with a 401 response if it does not have a valid Authorization header. The
Authorization header should include a parameter, where n refers to
one of eight VoIP user accounts that can be configured on the ATA device. The
credentials are computed based on the corresponding password using Message
Digest 5 (MD5). The parameter must match one of the VoIP accounts
stored on the ATA device. Each VoIP user account contains the information listed
below.

Configuring the PSTN (FXO) Gateway on the SPA3102
How VoIP-To-PSTN Calls Work

NOTE If Authentication is disabled, a default dial plan is used for all unknown VoIP users.

Two-Stage Dialing
In two-stage dialing, the ATA device takes the FXO port off-hook but does not
automatically dial any digits after accepting the call. To invoke two-stage dialing,
the VoIP caller should INVITE the PSTN Line without the user-id in the Request-URI
or with a user-id that matches exactly the of the PSTN Line. A different
user-id in the Request-URI is treated as a request for one-stage dialing if onestage dialing is enabled, or dropped by the ATA device (as if no user-id is given) if
one-stage dialing is disabled.

NOTE If Authentication is disabled, a default dial plan is assigned to all VoIP callers.

HTTP Digest Authentication can be also used for two-stage dialing, as in onestage dialing. If using HTTP Digest Authentication or Authentication is disabled, the
VoIP caller should hear the PSTN dial tone right after the call is answered (by a SIP
200 response).
If PIN Authentication is enabled, the VoIP caller is prompted to enter a PIN number
after the ATA device answers the call. The PIN number must end with a # key. The
inter-PIN-digit timeout is 10 seconds (not configurable). Up to eight VoIP caller PIN
numbers can be configured on the ATA device. A dial plan can be selected for
each PIN number. If the caller enters a wrong PIN or the ATA device times out
waiting for more PIN digits, the ATA device tears down the call immediately with a
BYE request.

NOTE When the source address of the INVITE is 127.0.0.1, authentication is automatically

disabled because this is a call by the local user. This applies to both one-stage and
two-stage dialing.

How PSTN-To-VoIP Calls Work
PSTN-To-VoIP calls can be made with two-stage dialing only. The only
authentication method available is the PIN method.
The ATA device takes the FXO port off hook after a configurable number of rings. If
PIN Authentication is enabled, it prompts the caller to enter the PIN number
followed by a # key. The Inter-PIN-digit timeout is set at 10 seconds. Up to eight
PSTN PIN numbers can be configured in the ATA device. If the given PIN does not
match any of the PSTN PIN values, the ATA device plays the reorder tone to the
FXO port for up to 10 seconds, and then takes the FXO port on-hook. If the given
PIN matches one of PSTN PIN values, the ATA device plays dial tone to the FXO
port and is ready to accept digits for the target VoIP number from the PSTN caller.
The collected digits are processed by the dial plan associated with the PIN
number.

NOTE If Authentication is disabled, a default dial plan is used for all PSTN callers.

ATA Administration Guide

Configuring the PSTN (FXO) Gateway on the SPA3102
How PSTN-To-VoIP Calls Work

Terminating Gateway Calls
There are two call legs in a PSTN gateway call: the PSTN call leg and the VoIP call
leg. A gateway call is terminated when either call leg is ended. When the call
terminates, the FXO port goes on-hook so the PSTN line can be used again. The
ATA device detects that the PSTN call leg is ended when one of the following
conditions occurs during a call:

•

The PSTN Line voltage drops to a very low value (this occurs if the line is
disconnected from the PSTN service or if the PSTN switch provides a CPC
signal).

•

A polarity reversal or disconnect tone is detected at the FXO port.

•

There is no voice activity for a configurable period of time in either direction
at the FXO port.

When any of the above conditions occur, the ATA device takes the FXO port on
hook and sends a BYE request to end the VoIP call leg. On the other hand, when
the ATA device receives a SIP BYE from the VoIP during a call, it takes the FXO port
on hook to end the PSTN call leg.
In addition, the ATA device can also send a refresh signal periodically to the VoIP
call leg to determine whether the call leg is still up. If a refresh operation fails, the
ATA device ends both call legs.
The following table lists parameters for terminating gateway calls.

Configuring VoIP Failover to PSTN
When power is disconnected from the SPA3102, the FXS port is connected to the
FXO port. In this case, the telephone attached to the FXS port is electrically
connected to the PSTN service via the FXO port. When power is applied to the
ATA device, the FXS port is disconnected from the FXO port. However, if the PSTN
line is in use when the power is applied to the ATA device, the relay is not flipped
until the PSTN line is released. This is done so that the ATA device does not
interrupt any call in progress on the PSTN line.
When Line 1 VoIP service is down (because of registration failure or loss of
network link), the ATA device can be configured to automatically route all outbound
calls to the internal gateway using the parameter listed below.

provider. In this case, both lines receive inbound calls to this VoIP account.
The PSTN Line should be configured with a sufficiently long answer delay
before the call is automatically answered to allow for the function of the
PSTN gateway.

•

If the service provider does not allow more than one register contact, the
PSTN Line should not register. In this case, only Line 1 rings on the inbound
call to this VoIP account because it is the only line registered with the
service provider.

•

Line 1 can have the call forwarded to the PSTN Line after a few seconds
using the Call-Forward-On-No-Answer feature with gw0 as the forward
destination. Similarly, Line 1 can apply Call-Forward-All, Call-Forward-OnBusy, and Call-Forward-Selective feature, and direct the caller to the PSTNGateway.

•

Only PIN authentication is allowed when a VoIP caller is forwarded to the
PSTN-gateway from Line 1. If HTTP Authentication is used, the caller is not
authenticated.

•

When using the Forward-To-GW0 feature, you can forward the caller to a
specific PSTN number, using the syntax @gw0 in the
forward destination. When using this with Call-Forward-Selective, you can
develop some interesting applications. For example, you can forward all
callers with 408 area code to 14081234567, or all callers with 800 area
code to 18005558355 (This is the number for Tell Me). When this syntax is
used, authentication is not used and the target PSTN number is
automatically dialed by the ATA device after the caller is forwarded to gw0.

Other Options
This section describes other options provided by the ATA device. It includes the
following topics:

•

”PSTN Call to Ring Line 1” section on page104

•

”Symmetric RTP” section on page104

•

”Call Progress Tones” section on page105

PSTN Call to Ring Line 1
This feature allows a PSTN caller to ring Line 1. When the PSTN line rings, the
PSTN Line makes a local VoIP call to Line 1. If Line 1 is busy, it stops. After a given
number of rings, the VoIP gateway picks up the call.

Symmetric RTP
The Symmetric RTP parameter is used to send audio RTP to the source IP and
port of the inbound RTP packets. This facilitates NAT traversal.
The following table lists symmetric RTP parameters.

Call Scenarios

Call Progress Tones
The ATA has configurable call progress tones. Call progress tones are generated
locally on the ATA, so an end user is advised of status (such as ringback).
Parameters for each type of tone (for instance a dial tone played back to an end
user) may include:

•

number of frequency components

•

frequency and amplitude of each component

•

cadence information.

When one VoIP account is shared between the FXS and PSTN Lines, the following
parameters are recommended to be set. See the Regional page in the “ATA Voice
Field Reference,” on page121 for these and other call progress tone parameters.

Call Progress Tone

Description

VoIP PIN Tone

This tone is played to prompt a VoIP caller to enter a PIN number.

PSTN PIN Tone

This tone is played to prompt a PSTN caller to enter a PIN
number.

Outside Dial Tone

During two-stage PSTN-gateway dialing and with a dial plan
assigned, the ATA device collects digits from the VoIP caller and
processes the number using the dial plan. The ATA device plays
the Outside Dial Tone to prompt the VoIP caller to enter the
PSTN number. This tone should be specified to sound different
from the PSTN dial tone.

Call Scenarios
This section describes some typical scenarios where the ATA device can be
applied. Some terms are introduced in the first few sections and reused in later
sections. This section includes the following topics:

105

Configuring the PSTN (FXO) Gateway on the SPA3102
Call Scenarios

PSTN to VoIP Call with and Without Ring-Thru
The PSTN caller calls the PSTN line connected to the FXO port. Ring-Thru is
disabled. After the call rings for a delay equal to the value in PSTN Answer Delay,
the VoIP gateway answers the call and prompts the PSTN caller to enter a PIN
number (assuming PIN authentication is enabled). After a valid PIN is entered, the
caller is prompted to dial the VoIP number. A dial plan is selected according to the
PIN number entered by the caller. If authentication is disabled, the default PSTN
dial plan is used. Note than the dial plan choice cannot be 0 for a PSTN caller.

NOTE A PSTN Access List in terms of Caller ID (ANI) patterns can be configured into the

ATA device to automatically grant access to the PSTN caller without entering the
PIN. In this case, the default PSTN dial plan is also used.
The same scenario can be implemented using Ring-Thru. When the PSTN line
rings, Line 1 rings also. This feature is called Ring-Thru. If Line1 is picked up before
the VoIP gateway auto-answers, it is connected to the PSTN call. Line 1 hears a
call waiting tone if it is already connected to another call.

VoIP to PSTN Call With and Without Authentication
This section describes three scenarios with and without authentication and
includes the following topics:

•

”Using PIN Authentication” section on page106

•

”Using HTTP Digest Authentication” section on page107

•

”Without Authentication” section on page108

Using PIN Authentication
This scenario assumes that the PSTN Line has a different VoIP account than the
Line 1 account. The VoIP caller calls the FXO number, which auto-answers after
VoIP Answer Delay. The ATA device then prompts the VoIP caller for a PIN. When a
valid PIN is entered, the SPA3102 plays the Outside Dial Tone and prompts the
caller to dial the PSTN number.

ATA Administration Guide

106

Configuring the PSTN (FXO) Gateway on the SPA3102
Call Scenarios

The number dialed is processed by the dial plan corresponding to the VoIP caller.
If the dial plan choice is 0, no dial plan is needed and the user hears the PSTN dial
tone right after the PIN is entered. If the dial plan choice is not 0, the final number
returned from the dial plan after the complete number is dialed by the caller is
dialed to the PSTN. The caller does not hear the PSTN dial tone (except for a little
leakage before the first digit of the final number is auto-dialed by the ATA device).
If the PSTN Line is busy (off-hook, ringing, or PSTN line not connected) when the
VoIP caller calls, the ATA device replies with 503. If the PIN number is invalid or
entered after the VoIP call leg is connected, the ATA device plays the reorder tone
to the VoIP caller and eventually ends the call when the reorder tone times out.

NOTE If VoIP Caller ID Pattern is specified and the VoIP caller ID does not match any of the

given patterns, the ATA device rejects the call with a 403. This rule applies
regardless of the authentication method, even when the source IP address of the
INVITE request is in the VoIP Access List .

Using HTTP Digest Authentication
The same scenario can be implemented with HTTP digest authentication when
the calling device supports the configuration of a auth-ID and password to access
the ATA device PSTN gateway. When the VoIP caller calls the PSTN Line, the ATA
device challenges the INVITE request with a 401 response. The calling device
should then provide the correct credentials in a subsequent retry of the INVITE,
computed with the auth-ID and password using MD5.
If the credentials are correct, the target number specified in the user-id field of the
INVITE Request-URI is processed by the dial plan corresponding to the VoIP user
(assuming the dial plan choice is not 0). The final number is then auto-dialed by the
ATA device.
If the credentials are incorrect, the ATA device challenges the INVITE again. If the
auth-ID does not exist in the ATA device configuration, the ATA device replies 403
to the INVITE. If the target number is invalid according to the corresponding dial
plan, the ATA device also replies 403 to the INVITE. Again, if the PSTN Line is busy
at the time of the call, the ATA device replies 503.
NOTE: HTTP Digest Authentication is one way to perform one-stage dialing of a
VoIP-To-PSTN call. The other way is with no authentication require. However, if the
target number is not specified in the Request-URI or the number matches the
account user-id of the PSTN Line, the call reverts to two-stage dialing.

ATA Administration Guide

107

Configuring the PSTN (FXO) Gateway on the SPA3102
Call Scenarios

Without Authentication
This scenario can also be implemented without authentication, using one-stage or
two-stage dialing, as in the HTTP Authentication case. The default VoIP caller dial
plan is used in this scenario. Authentication is performed when the method is none
or when the source IP address of the inbound INVITE matches one of the VoIP
Access List patterns.
The following table lists the parameters used in VoIP to PSTN Call With and
Without Authentication.

Parameter

Web
Page

Description

Value

VoIP

PSTN
Line

Delay in seconds before auto-answering
inbound VoIP calls for the FXO account.

The range is 0255. The
default is 3.

Outside Dial
Tone

Regional

Alternative to the Dial Tone. It prompts
the user to enter an external phone
number, as opposed to an internal
extension. It is triggered by a comma
encountered in the dial plan.

The default is
420@-19;10(*/
0/1).

VoIP Caller
ID Pattern

PSTN
Line

A comma-separated list of caller
number templates such that callers
with numbers not matching any of
these templates are rejected for
PSTN gateway service regardless of
the setting of the authentication
method. The comparison is applied
before the access list is applied. If
this parameter is blank (not
specified), all callers are considered
for PSTN gateway service.

For example:
1408*,
1512???1234.

A comma-separated list of IP address
templates, such that callers with a
source IP address matching any of
the templates are accepted for PSTN
gateway service without further
authentication.

For example:
192.168.*.*,
66.43.12.1??.

Call Scenarios

Call Forwarding to PSTN Gateway
This section describes a number of scenarios that forward calls to the PSTN
gateway. It includes the following topics:

•

”Forward-On-No-Answer to the PSTN Gateway” section on page109

•

”Forward-All to the PSTN gateway” section on page109

•

”Forward to a Particular PSTN Number” section on page110

•

”Forward-On-Busy to PSTN Gateway or Number” section on page110

Forward-On-No-Answer to the PSTN Gateway
In this scenario, Line 1 is configured to Cfwd No Ans Dest to the PSTN Gateway.
The scenario is implemented by setting User 1 to forward to gw0 on no answer,
with Cfwd No Ans Delay set to six seconds.
The caller calls Line 1 and if Line 1 is not picked up after six seconds, the PSTN
Line picks up the call and the call reverts to a PSTN-Gateway call, as described
above. In this case, HTTP authentication is not allowed because Line 1 does not
authenticate inbound INVITE requests. If you need to authenticate the VoIP caller in
this case, you must select the PIN authentication method, or else the caller is not
authenticated.

NOTE If the PSTN Line is busy at the moment of the forward, it does not answer the VoIP

call. The call forward rule is ignored and Line 1 continues to ring.

Forward-All to the PSTN gateway
In this scenario, Line 1 is configured with Cfwd All Dest parameter to the PSTN
gateway.This scenario is the same the previous case, except the FXO picks up the
Line 1 call immediately.
If the PSTN Line is busy at the moment of the call, the PSTN Line does not pick up
the call, the call forward rule is ignored, and Line 1 continues to ring.

ATA Administration Guide

109

Configuring the PSTN (FXO) Gateway on the SPA3102
Call Scenarios

Forward to a Particular PSTN Number
In this scenario, the forward destination is set to @gw0>. This is
the same as in the previous examples, except that the ATA device automatically
dials the given target number on the PSTN line right after it answers the VoIP call
leg. This is a special case of one-stage dialing where the target number is
specified in the configuration. The caller is not authenticated in this case
regardless of the authentication method. However, the caller is still limited by the
VoIP Caller ID Pattern parameter

Forward-On-Busy to PSTN Gateway or Number
This scenario is similar to the previous cases of call forwarding to gw0, but this
applies when Line 1 is active.

RTCP Tx Interval

Interval for sending out RTCP sender reports on an active
connection. It can range from 0 to 255 seconds. During an
active connection, the ATA device can be programmed to
send out compound RTCP packet on the connection. Each
compound RTP packet except the last one contains a SR
(Sender Report) and a SDES.(Source Description). The last
RTCP packet contains an additional BYE packet. Each SR
except the last one contains exactly 1 RR (Receiver
Report); the last SR carries no RR. The SDES contains
CNAME, NAME, and TOOL identifiers. The CNAME is set to
@, NAME is set to (or
Anonymous if user blocks caller ID), and TOOL is set to the
Vendor/Hardware-platform-software-version (such as
Cisco/ATA device-1.0.31(b)). The NTP timestamp used in
the SR is a snapshot of the ATA device’s local time, not the
time reported by an NTP server. If the ATA device receives
a RR from the peer, it attempts to compute the round trip
delay and show it as the value
(ms) in the Info section of ATA device web page.

CPC Delay

Delay in seconds after caller hangs up when the ATA
device starts removing the tip-and-ring voltage to the
attached equipment of the called party. Range: 0–255
seconds. ATA device has had polarity reversal feature
since release 1.0 which can be applied to both the caller
and the callee end. This feature is generally used for
answer supervision on the caller side to signal to the
attached equipment when the call has been connected
(remote end has answered) or disconnected (remote end
has hung up). This feature should be disabled for the called
party (in other words, by using the same polarity for
connected and idle state) and the CPC feature should be

Referral Services
Codes

These codes tell the ATA device what to do when the user
places the current call on hold and is listening to the
second dial tone.
One or more *code can be configured into this parameter,
such as *98, or *97|*98|*123, etc. Max total length is 79
chars. This parameter applies when the user places the
current call on hold (by Hook Flash) and is listening to
second dial tone. Each *code (and the following valid target
number according to current dial plan) entered on the
second dial-tone triggers the ATA device to perform a blind
transfer to a target number that is prepended by the
service *code.
For example, after the user dials *98, the ATA device plays
a special dial tone called the Prompt Tone while waiting for
the user the enter a target number (which is checked
according to dial plan as in normal dialing). When a
complete number is entered, the ATA device sends a blind
REFER to the holding party with the Refer-To target equals
to *98 target_number. This feature allows the ATA device to
hand off a call to an application server to perform further
processing, such as call park.
The *codes should not conflict with any of the other vertical
service codes internally processed by the ATA device. You
can empty the corresponding *code that you do not want
to ATA device to process.

ATA Administration Guide

157

ATA Voice Field Reference

Feature Dial
Services Codes

These codes tell the ATA device what to do when the user
is listening to the first or second dial tone.
One or more *code can be configured into this parameter,
such as *72, or *72|*74|*67|*82, etc. Max total length is 79
chars. This parameter applies when the user has a dial tone
(first or second dial tone). Enter *code (and the following
target number according to current dial plan) entered at the
dial tone triggers the ATA device to call the target number
prepended by the *code. For example, after user dials *72,
the ATA device plays a special tone called a Prompt tone
while awaiting the user to enter a valid target number.
When a complete number is entered, the ATA device sends
a INVITE to *72 target_number as in a normal call. This
feature allows the proxy to process features like call
forward (*72) or BLock Caller ID (*67).
The *codes should not conflict with any of the other vertical
service codes internally processed by the ATA device. You
can empty the corresponding *code that you do not want
to ATA device to process.
You can add a parameter to each *code in Features Dial
Services Codes to indicate what tone to play after the
*code is entered, such as *72‘c‘|*67‘p‘. Below are a list of
allowed tone parameters (note the use of back quotes
surrounding the parameter w/o spaces)
‘c‘ =
‘d‘ =
‘m‘ =
‘o‘ =
‘p‘ =
‘s‘ =
‘x‘ = No tones are place, x is any digit not used above
If no tone parameter is specified, the ATA device plays
Prompt tone by default.
If the *code is not to be followed by a phone number, such
as *73 to cancel call forwarding, do not include it in this
parameter. In that case, simple add that *code in the dial
plan and the ATA device send INVITE *73@..... as usual
when user dials *73.

value is 0, this means that the date to start or end daylight
saving is exactly the date given. In that case, the
value must not be negative. If the value is not 0
and the value is positive, then daylight saving starts
or ends on the value on or after the date given.
If the value is not 0 and the value is
negative, then daylight saving starts or ends on the

SAS Inbound RTP
Sink

This setting works around devices that do not play inbound
RTP if the streaming audio server line declares itself as a
send-only device and tells the client not to stream out
audio. Enter a Fully Qualified Domain Name (FQDN) or IP
address of an RTP sink; this value is used by the streaming
audio server line in the SDP of its 200 response to an
inbound INVITE message from a client.
The purpose of this parameter is to work around devices
that do not play inbound RTP if the SAS line declares itself
as a send-only device and tells the client not to stream out
audio. This parameter is a FQDN or IP address of a RTP
sink to be used by the SPA SAS line in the SDP of its 200
response to inbound INVITE from a client. It will appear in
the c = line and the port number and, if specified, in the m =
line of the SDP. If this value is not specified or equal to 0,
then c = 0.0.0.0 and a=sendonly will be used in the SDP to
tell the SAS client to not to send any RTP to this SAS line. If
a non-zero value is specified, then a=sendrecv and the
SAS client will stream audio to the given address. Special
case: If the value is $IP, then the SAS line’s own IP address
is used in the c = line and a=sendrecv. In that case the SAS
client will stream RTP packets to the SAS line.
The default value is empty.

SIP Settings section

Field

Description

SIP Transport

The TCP choice provides “guaranteed delivery”, which
assures that lost packets are retransmitted. TCP also
guarantees that the SIP packages are received in the same
order that they were sent. As a result, TCP overcomes the
main disadvantages of UDP. In addition, for security
reasons, most corporate firewalls block UDP ports. With
TCP, new ports do not need to be opened or packets
dropped, because TCP is already in use for basic activities
such as Internet browsing or e-commerce. Options are:
UDP, TCP, TLS. The default is UDP.
Applies to SPA2102, SPA3102, and WRP400.

SIP Port

Port number of the SIP message listening and transmission

2617) message. To use this feature, select yes. Otherwise,
select no.
The default is yes.

SIP Proxy-Require

The SIP proxy can support a specific extension or behavior
when it sees this header from the user agent. If this field is
configured and the proxy does not support it, it responds
with the message, unsupported. Enter the appropriate
header in the field provided.

SIP Remote-PartyID

To use the Remote-Party-ID header instead of the From
header, select yes. Otherwise, select no.
The default is yes.

Audio Configuration section
A codec resource is considered as allocated if it has been included in the SDP
codec list of an active call, even though it eventually may not be the one chosen for
the connection. So, if the G.729a codec is enabled and included in the codec list,
that resource is tied up until the end of the call whether or not the call actually uses
G.729a. If the G.729a resource is already allocated and since only one G.729a
resource is allowed per device, no other low-bit-rate codec may be allocated for
subsequent calls; the only choices are G711a and G711u. On the other hand, two
G.723.1/G.726 resources are available per device.
Therefore it is important to disable the use of G.729a in order to guarantee the

Enable IP Dialing

Enable or disable IP dialing.
If IP dialing is enabled, one can dial [user-id@]a.b.c.d[:port],
where ‘@’, ‘.’, and ‘:’ are dialed by entering *, user-id must be
numeric (like a phone number) and a, b, c, d must be
between 0 and 255, and port must be larger than 255. If
port is not given, 5060 is used. Port and User-Id are
optional. If the user-id portion matches a pattern in the dial
plan, then it is interpreted as a regular phone number
according to the dial plan. The INVITE message, however, is
still sent to the outbound proxy if it is enabled.
The default is no.

Call Capacity

Maximum number of calls allowed on this trunk group.
Choices: 1-15 or unlimited (16 calls). Default is unlimited.
Both incoming call and outgoing call are counted towards
this limit. The call capacity has the following impact on call
handling:

ATA Administration Guide

•

Inbound calls: When the limit is reached, the Trunk SUA
replies 486 to the caller.

•

Outbound calls: When the limit is reached, the Line SUA plays
a fast busy tone to the caller. Note that a trunk line can make
an outgoing call only through its own trunk. If that trunk
reaches full capacity, it will not attempt to failover to use other
trunks

186

ATA Voice Field Reference
Trunk Group page (SPA8000)

Contact List

This parameter determines which trunk lines to ring on an
incoming call.
When an incoming call is detected by the Trunk SUA (SIP
User Agent), the SUA first checks if there is capacity to
handle the call. If not, the SUA rejects the call with a 486
response. If there is spare capacity, the SUA consults the
Contact List to determine which lines to ring (that is, for the
proxy to send SIP INVITE to), and starts "hunting."
The Contact List specifies the lines, the hunt method, and
other options.
EXAMPLES:

•

1,2,3,4,5,6,7,8,hunt=re;*;1
Lines 1 through 8 are participating (1,2,3,4,5,6,7,8).
The Trunk SUA will hunt to each specified line in the specified
order (hunt=re). The call stays with a selected line until the
call is either answered, rejected, or cancelled by the caller
(*). The Trunk SUA replies 486 right away if no line is
available to ring at the moment (1).

•

?,hunt=al;30;0,cfwd=14089993326
A wildcard character is used to represent “all trunk lines.” All
lines ring simultaneously (hunt=al). If there is no answer
after 30 seconds (30), the call is forwarded to the specified
number (cfwd=14089993326) .

•

?,hunt=ra;12;1,cfwd=14089993326
A wildcard character is used to represent “all trunk lines.” The
Trunk SUA hunts in random order (hunt=ra). If there is no
answer within 12 seconds (12), the Trunk SUA chooses
another line at random. If there is no answer after 1 round (1),
the call is forwarded to forwarded to the specified number
(cfwd=14089993326).

Contact List
(continued)

NOTES:

•

The Trunk SUA rings only trunk lines (lines that are assigned
to a trunk group through the Voice tab > Line page, Trunk
Group field).
•
•

•

ATA Administration Guide

The Trunk SUA will not ring any standalone lines that are included in
the Contact List.
The Trunk SUA will ring any trunk line that is included in the list, even if
it is not assigned to this particular trunk.

You can instruct the SPA8000 to hunt only the phones that are
on-hook, through the Voice tab > SIP page, Trunking
Parameters section, Hunt Policy field. See “Trunking

the number before sending out INVITE to the ITSP. This
Trunk Dial Plan typically is redundant since the trunk should
trust the number sent by the Line SUA. By default the trunk
dial plan allows any non-empty number: ([*#0-9AD][*#0-9A-D].)

Audio Configuration section
A codec resource is considered as allocated if it has been included in the SDP
codec list of an active call, even though it eventually may not be the one chosen for
the connection. So, if the G.729a codec is enabled and included in the codec list,
that resource is tied up until the end of the call whether or not the call actually uses
G.729a. If the G729a resource is already allocated and since only one G.729a
resource is allowed per device, no other low-bit-rate codec may be allocated for
subsequent calls; the only choices are G711a and G711u. On the other hand, two
G.723.1/G.726 resources are available per device.
Therefore it is important to disable the use of G.729a in order to guarantee the
support of two simultaneous G.723/G.726 codec.

Preferred Codec

Preferred codec for all calls. (The actual codec used in a
call still depends on the outcome of the codec negotiation
protocol.) Select one of the following: G711u, G711a,

the caller with a 401 response). The VoIP caller whose
authentication user-id equals to this ID is referred to VoIP
User 1 of this SPA.
NOTE: If the caller specifies an authentication user-id that
does not match any of the VoIP User Auth ID’s, the INVITE
will be rejected with a 403 response.
The default is blank.

Disconnect Tone

This value is the tone script which describes to the SPA the
tone to detect as a disconnect tone. The syntax follows a
standard Tone Script with some restrictions. Default value
is standard US reorder (fast busy) tone, for 4 seconds.
Restrictions:

•

2 frequency components must be given. If single frequency
is desired, the same frequency is used for both

•

The tone level value is not used. –30 (dBm) should be used
for now.

•
•

Only 1 segment set is allowed

•

6 segments of on/off time (seconds) can be specified. A 10%
margin is used to validated cadence characteristics of the
tone.

Total duration of the segment set is interpreted as the
minimum duration of the tone to trigger detection

Troubleshooting

This appendix provides solutions to problems that may occur during the
installation and operation of the ATA devices.

NOTE If you can't find an answer here, visit www.cisco.com/go/smallbiz.

Q. I want to use a different computer to access the administration web server.
The address I entered did not work.
A. Use the Interactive Voice Response Menu to find out the Internet IP address.
Follow these steps:
1. Use a telephone connected to the Phone 1 port of the ATA device.
2. Press **** (in other words, press the star key four times).
3. After the greeting plays, press 110#.
4. Write down the IP address as it is announced.
5. Press 7932#.
6. Press 1 to enable WAN access to the administration web server.
7. Open the web browser on a networked computer.
8. Start Internet Explorer and enter the IP address of the ATA device.
Q. I’m trying to access the ATA administration web server, but I do not see the
login screen. Instead, I see a screen saying, “404 Forbidden.”
A. If you are using Windows Explorer, perform the following steps until you see the
administration web server login screen (Mozilla requires similar steps).
1. Click File. Make sure Work Offline is NOT checked.
2. Press CTRL + F5. This is a hard refresh, which forces Windows Explorer to load
new webpages, not cached ones.

ATA Administration Guide

235

Troubleshooting

3. Click Tools. Click Internet Options. Click the Security tab. Click the Default
level button. Make sure the security level is Medium or lower. Then click the OK
button.
Q. How do I save my current configuration?
A. Currently, the only way is to do HTTPGET from an HTTP client, from which you
get the entire HTML page. Alternatively, from your browser you can select File >
Save as > HTML from any of the administration web server pages. Do this in
Admin, Advanced mode.
This saves all the tabs into one HTML file. This HTML file is helpful to provide to our
support team when you have a problem or technical question.
Q. How do I debug my ATA device? Is there a syslog?
A. The ATA devices send out debug information via syslog to a syslog server. The
ports can be configured (by default the port is 514).
1. Make sure you do not have firewall running on your PC that could block port 514.
2. On the administration web server System tab, set Debug Server as the IP
address and port number of your syslog server. Note that this address has to
be reachable from the ATA device.
3. Also, set Debug level to 3.
You do not need to change the value of the syslog server parameter.
4. To capture SIP signaling messages, under the Line tab, set SIP Debug Option to
Full.
The file output is syslog..log (for the default port setting,
syslog.514.log).
Q. How do I access the ATA device if I forget my password?
A. By default, the User and Admin accounts have no password. If the ITSP set the
password for either account and you do not know what it is, you need to contact
the ITSP. If the password for the user account was configured after you received
the ATA device, you can reset the device to the user factory default, which
preserves any provisioning completed by the ITSP. If the Admin account needs to
be reset, you have to perform a full factory reset, which also erases any
provisioning.
To reset the ATA device to the factory defaults, perform the following steps:
1. Connect an analog phone to the ATA device and access the IVR by pressing
****.

ATA Administration Guide

236

Troubleshooting

Press the appropriate code to reset the unit:

•

Press 877778# to reset the unit to the defaults as it shipped from the ITSP. This
will reset the User account password to the default of blank.

•

Press 73738# to perform a full reset of unit to the factory default settings. The
Admin account password will be reset to the default of blank.

2. Press 1 to confirm the operation.
Press * to cancel the operation.
3. Login to the unit using the User or Admin account without a password and
reconfigure the unit as necessary.
Q. My ATA device is behind a NAT device or firewall and I’m unable to make a
call or I’m only receiving a one-way connection. What should I do?
A. Complete the following steps.
1. Configure your router to port forward “TCP port 80" to the IP address currently
being used by your ATA device. If you do this often, we suggest that you use
static IP address for the ATA device, instead of DHCP. (For help with port
forwarding, consult your router documentation)
2. On the Line tab of the administration web server, change the value of Nat
Mapping Enable to yes. On the SIP tab; change Substitute VIA Addr to yes, and
the EXT IP parameter to the IP address of your router.
3. Make sure you are not blocking the UDP PORT 5060,5061 and port for UDP
packets in the range of 16384-16482. Also, disable “SPI” if this feature is
provided by your firewall. Identify the SIP server to which the ATA device is
registering, if it supports NAT, using the Outbound Proxy parameter.
4. Add a STUN server to allow traversal of UDP packets through the NAT device.
On the SIP tab of the administration web server, set STUN Enable to yes, and
enter the IP address of the STUN server in STUN Server.
STUN (Simple Traversal of UDP through NATs) is a protocol defined by RFC
3489, that allows a client behind a NAT device to find out its public address, the
type of NAT it is behind, and the port associated on the Internet connection
with a particular local port. This information is used to set up UDP
communication between two hosts that are both behind NAT routers. Open
source STUN software can be obtained at the following website:
http://www.voip-info.org/wiki-Open+Source+VOIP+Software

ATA Administration Guide

237

Troubleshooting

D
NOTE STUN does not work with a symmetric NAT router. Enable debug through

syslog (see FAQ#10), and set STUN Test Enable to yes. The messages
indicate whether you have symmetric NAT or not.
