2. “#” returns to the main menu
3. “9” functions as the ENTER key in many cases to confirm an option
4. All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP
address. For IP address, add 0 before the digits if the digits are less than 3 (i.e. - 192.168.0.26
should be key in like 192168000026. No decimal is needed).
5. Key entry can not be deleted but the phone may prompt error once it is detected
PLACING A PHONE CALL
PHONE OR EXTENSION NUMBERS
1. Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”); or
FIRMWARE VERSION 1.0.7.6
HT502 USER MANUAL
Page 16 of 48
2. Dial the number directly and press # (Use # as dial key” must be configured in web configuration).
Examples:
1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds.
2. Dial an outside number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international
code) followed by the phone number. Press # or wait for 4 seconds. Check with your VoIP service
provider for further details on prefix numbers.
DIRECT IP CALLS
Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to
talk to each other in an ad hoc fashion without a SIP proxy.
Elements necessary to completing a Direct IP Call:
1. Both HT502 and other VoIP Device, have public IP addresses, or
2. Both HT502 and other VoIP Device are on the same LAN using private IP addresses, or
3. Both HT502 and other VoIP Device can be connected through a router using public or private IP
addresses (with necessary port forwarding or DMZ).
HT502 supports two ways to make Direct IP Calling:
Using IVR
1. Pick up the analog phone then access the voice menu prompt by dial “***”
2. Dial “47” to access the direct IP call menu
3. Enter the IP address after the dial tone and voice prompt “Direct IP Calling”
Using Star Code
1. Pick up the analog phone then dial “*47”
2. Enter the target IP address.
Note: NO dial tone will be played between step 1 and 2.
Destination ports can be specified using “*” (encoding for “:”) followed by the port number.
FIRMWARE VERSION 1.0.7.6
HT502 USER MANUAL
Page 17 of 48
Examples of Direct IP Calls:
a) If the target IP address is 192.168.0.160, the dialing convention is
*47 or Voice Prompt with option 47, then 192*168*0*160.
followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case,
the default destination port 5060 is used if no port is specified.
b) If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:
*47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the “#” key
if it is configured as a send key or wait for 4 seconds.
NOTE: When completing direct IP call, the “Use Random Port” should set to “NO”. You cannot make
direct IP calls between FXS1 to FXS2 since they are using same IP.
CALL HOLD
Place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button).
Press the “flash” button again to release the previously held Caller and resume conversation. If no “flash”
button is available, use “hook flash” (toggle on-off hook quickly). You may drop a call using hook flash.
CALL WAITING
Call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled. Toggle
between incoming call and current call by pressing the “flash” button. First call is placed on hold. Press
the “flash” button to toggle between two active calls.
CALL TRANSFER
Blind Transfer
Assume that call Caller A and B are in conversation. A wants to Blind Transfer B to C:
3. Caller A presses FLASH on the analog phone to hear the dial tone.
4. Caller A dials *87 then dials caller C’s number, and then # (or wait for 4 seconds)
5. Caller A will hear the confirm tone. Then, A can hang up.
NOTE: “Enable Call Feature” must be set to “Yes” in web configuration page.
FIRMWARE VERSION 1.0.7.6
HT502 USER MANUAL
Page 18 of 48
Caller A can place a call on hold and wait for one of three situations:
1. A quick confirmation tone (similar to call waiting tone) followed by a dial-tone. This indicates the
transfer is successful (transferee has received a 200 OK from transfer target). At this point, Caller
A can either hang up or make another call.
2. A quick busy tone followed by a restored call (on supported platforms only). This means the
transferee has received a 4xx response for the INVITE and we will try to recover the call. The
busy tone is just to indicate to the transferor that the transfer has failed.
3. Continuous busy tone. The phone has timed out.
Note: continuous busy tone does not indicate the transfer has been successful, nor does it indicate
the transfer has failed.
It often means there was a failure to receive second NOTIFY – check
firmware for most recent release.
Attended Transfer
Assume that Caller A and B are in conversation. Caller A wants to Attend Transfer B to C:
1. Caller A presses FLASH on the analog phone for dial tone.
2. Caller A then dials Caller C’s number followed by # (or wait for 4 seconds).
3. If Caller C answers the call, Caller A and Caller C are in conversation. Then A can hang up to
complete transfer.
4. If Caller C does not answer the call, Caller A can press “flash” to resume call with Caller B.
NOTE: When Attended Transfer fails and A hangs up, the HT502 will ring back user A to remind A that B
is still on the call. A can pick up the phone to resume conversation with B.
3­WAY CONFERENCING
The HT502 supports Bellcore style 3-way Conference.
Instructions for 3-way conference:
Assume that call party A and B are in conversation. Caller A(HT502) wants to bring third Caller C into
conference:
1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial tone.
2. A dials C’s number then # (or wait for 4 seconds).
FIRMWARE VERSION 1.0.7.6
HT502 USER MANUAL
Page 19 of 48
3. If C answers the call, then A presses FLASH to bring B, C in the conference.
4. If C does not answer the call, A can press FLASH back to talk to B.
5. If A presses FLASH during conference, C will be dropped out.
6. If A hangs up, the conference will be terminated for all three parties when configuration “Transfer
on Conference Hangup” is set to “No”. If the configuration is set to “Yes”, A will transfer B to C so
that B and C can continue the conversation.
FAX SUPPORT
HT502 supports FAX in two modes: 1) T.38 (Fax over IP) and 2) fax pass through. T.38 is the preferred
method because it is more reliable and works well in most network conditions. If the service provider
supports T.38, please use this method by selecting Fax mode to be T.38 (default). If the service provider
does not support T.38, pass-through mode can be used.

CONFIGURING THE HT502 VIA WEB BROWSER
HT502 has an embedded Web server that will respond to HTTP GET/POST requests. It also has
embedded HTML pages that allow users to configure the HT502 through a web browser such as
Microsoft’s IE, AOL’s Netscape or Mozilla Firefox installed on Windows or Unix OS. (Macintosh OS is not
included).
ACCESS THE WEB CONFIGURATION MENU
The HT502 HTML configuration page can be accessed via LAN or WAN ports.
•
FROM THE LAN PORT:
1. Directly connect a computer to the LAN port
2. Open a command window on the computer
3. Type in “ipconfig /release”, the IP address etc becomes 0
4. Type in “ipconfig /renew”, the computer gets an IP address in 192.168.2.x segment by
default
5. Open a web browser, type in the default IP address of the LAN port. http://192.168.2.1. You
will see the log in page of the device.
•
FROM THE WAN PORT:
1. Follow table 4 to find the WAN side IP address.
2. Open a web browser, type in the WAN side IP address – for example:
http://HT502-WAN-IP-Address
Note:
•
WAN side HTTP access is disabled by default for security reason. You can enable HTTP access
on the configuration page by setting “WAN side HTTP access” to be YES.
•
Initial access to the configuration pages is always from the LAN port. The instructions are listed
above.
•
The IVR announces 12 digits IP address, you need to strip out the leading “0” in the IP address.
For ex. IP address: 192.168.001.014, you need to type in http://192.168.1.14 in the web browser.

The password is case sensitive with maximum length of 25 characters. The factory default password for
End User and administrator is “123” and “admin” respectively. Only an administrator can access the
“ADVANCED SETTING”, “FXS PORTs” configuration pages. Please reference the GUI pages using the
following link: http://www.grandstream.com/products/ht_series/ht502/documents/ht502_gui.zip .
NOTE: If you cannot log into the configuration page by using the default password, please check with
the VoIP service provider. It is most likely the VoIP service provider has provisioned the device and
configured for you therefore the password has already been changed.
IMPORTANT SETTINGS
The end-user must configure the following settings according to the local environment.
NOTE: Most
settings on the web configuration pages are set to the default values.
NAT SETTINGS
If you plan to keep the gateway within a private network behind a firewall, we recommend using STUN
Server. The following three (3) settings are useful in the STUN Server scenario:
1. STUN Server (under Advanced Settings webpage)
Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the
internet and enter it on this field. If using Public IP, keep this field blank.
2. Use Random Ports (under Advanced Settings webpage)
This setting depends on your network settings. Generally if you have multiple IP devices under the
same network, it should be set to Yes. If using a Public IP address, set this parameter to No.
3. NAT Traversal (under the Profile web pages)
Set this to Yes when gateway is behind firewall on a private network.

Use STUN keep-alive to detect WAN side network problems. If keep-alive request does
network connectivity
not yield any response for configured number of times, the device will restart the TCP/IP
stack. If the STUN server does not respond when the device boots up, the feature is
disabled.
Firmware Upgrade
Enables HT502 to download firmware or configuration file through either the TFTP, HTTP
and Provisioning
or HTTPS server.
Via TFTP Server
This is the IP address of the configured TFTP server. If selected and it is non-zero or not
blank, the HT502 retrieves the new configuration file or new code image from the
specified TFTP server at boot time. After 5 attempts, the system will timeout and will start
the boot process using the existing code image in the Flash memory. If a TFTP server is
configured and a new code image is retrieved, the new downloaded image is saved into
the Flash memory.
Note: Please do NOT interrupt the TFTP upgrade process (especially the power supply)
as this will damage the device. Depending on the local network, this process can take up
to 15 or 20 minutes.
Via HTTP / HTTPS

No Key Entry Timeout
Default is 4 seconds. Dialing process is completed and outgoing call is initiated if no
key entry occurs during this preconfigured interval.
Early Dial
Default is No. Use only if proxy supports 484 response.
This parameter controls
whether the phone will send an early INVITE each time a key is pressed when a user
dials a number. If set to “Yes”, an INVITE is sent using the dial-number collected thus
far; Otherwise, no INVITE is sent until the “(Re-)Dial” button is pressed or after about 5
seconds have elapsed if the user forgets to press the “Re-Dial” button.
The “Yes” option should be used ONLY if there is a SIP proxy configured and the proxy
server supports 484 Incomplete Address response. Otherwise, the call will likely be
rejected by the proxy (with a 404 Not Found error).
This feature does NOT work with and should NOT be enabled for direct IP-to-IP calling.

Use # as Dial Key
Allows users to configure the “#” key as the “Send” (or “Dial”) key. If set to “Yes”, “#”
will send the number. In this case, this key is essentially equivalent to the “Dial” key. If
set to “No”, this “#” key can be included as part of number.
Dial Plan
Dial Plan Rules:
1. Accept Digits: 1,2,3,4,5,6,7,8,9,0 , *, #, A,a,B,b,C,c,D,d
2. Grammar: x - any digit from 0-9;
•
xx+ - at least 2 digits number;
•
xx. – at least 2 digit number.
•
^ - exclude;
•
[3-5] - any digit of 3, 4, or 5;
•
[147] - any digit 1, 4, or 7;
•
<2=011> - replace digit 2 with 011 when dialing
•
< =1> - add a leading 1 to all numbers dialed, vice versa will
remove a 1 from the number dialed
•
| - or
• Example 1: {[369]11 | 1617xxxxxxx} – Allow 311, 611, 911, and any 11 digit
numbers with leading digits 1617
Example 2: {^1900x+ | <=1617>xxxxxxx} – Block any number of leading digits
1900 and add prefix 1617 for any dialed 7 digit numbers
•
Example 3: {1xxx[2-9]xxxxxx | <2=011>x+} –Allow any combinations of numbers
with 11 digits which has a leading digit 1, but 5th digit cannot be 0 or 1. Or any length
of numbers with a minimum of 2 digits beginning with 2, with the leading digit
replaced with 011.
3. Default: Outgoing - {x+}
Example of a simple dial plan used in a Home/Office in the US:
{ ^1900x. | <=1617>[2-9]xxxxxx | 1[2-9]xx[2-9]xxxxxx | 011[2-9]x. | [3469]11 }
Explanation of example rule (reading from left to right):
• ^1900x. - prevents dialing any number started with 1900
• <=1617>[2-9]xxxxxx - allows dialing to local area code (617) numbers by dialing
7 numbers and 1617 area code will be added automatically
• 1[2-9]xx[2-9]xxxxxx |- allows dialing to any US/Canada Number with 11 digits
length
• 011[2-9]x. - allows international calls starting with 011
• [3469]11 - allow dialing special and emergency numbers 311, 411, 611 and 911
Note: In some cases user wishes to dial strings such as *123 to activate voice mail or
other application provided by service provider. In this case * should be predefined

REBOOTING THE HT502 FROM REMOTE
Press the “Reboot” button at the bottom of the configuration menu to reboot the ATA remotely. The web
browser will then display a message window to confirm that reboot is underway. Wait 30 seconds to log in
again.
CONFIGURATION THROUGH A CENTRAL SERVER
Grandstream HT502 can be automatically configured from a central provisioning system.
When HT502 boot up, it will send TFTP or HTTP/HTTPS request to download configuration file,
“cfg000b82xxxxxx” or “cfg00082xxxxxx.xml”, where “000b82xxxxxx” is the LAN MAC address of the
HT502. It will first request “cfg000b82xxxxxx” then “cfg000b82xxxxxx.xml”
The configuration file can be downloaded via TFTP or HTTP/HTTPS from the central server. A service
provider or an enterprise with large deployment of HT502 can easily manage the configuration and
service provisioning of individual devices remotely from a central server.
Grandstream has a provisioning system called GAPS (Grandstream Automated Provisioning System) that
is used to support automated configuration of Grandstream devices. GAPS uses enhanced (NAT friendly)
TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each
individual Grandstream device for firmware upgrade, remote reboot, etc.
Grandstream provides GAPS service to VoIP service providers. Use GAPS for either simple redirection
or with certain special provisioning settings.
At boot-up, Grandstream devices by default point to
Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS
provision the devices with redirection settings so that they will be redirected to customer’s TFTP or
HTTP/HTTPS server for further provisioning.
Grandstream also provides a configuration tool to facilitate the task of generating device configuration
files. The Grandstream configuration tool is free to end users. The tool and configuration templates are
available for download from http://www.grandstream.com/support/tools .

SOFTWARE UPGRADE
Software upgrade can be done via either TFTP or HTTP. The corresponding configuration settings are in
the ADVANCED SETTINGS configuration page.
FIRMWARE UPGRADE THROUGH TFTP/HTTP/HTTPS
To upgrade via TFTP or HTTP/HTTPS, the “Firmware Upgrade and Provisioning upgrade via” field needs
to be set to TFTP HTTP or HTTPS, respectively. “Firmware Server Path” needs to be set to a valid URL
of a TFTP or HTTP server, server name can be in either FQDN or IP address format. Here are examples
of some valid URL.
e.g. firmware.mycompany.com:6688/Grandstream/1.0.7.6
e.g. firmware.grandstream.com
NOTES:
Firmware upgrade server in IP address format can be configured via IVR. Please refer to the
CONFIGURATION GUIDE section for instructions. If the server is in FQDN format, it must be set
via the web configuration interface.
Grandstream recommends end-user use the Grandstream HTTP server. Its address can be found
at http://www.grandstream.com/support/firmware . Currently the HTTP firmware server URL is
firmware.grandstream.com. For large companies, we recommend to maintain their own TFTP/
HTTP/HTTPS server for upgrade and provisioning procedures.
Once a “Firmware Server Path” is set, user needs to update the settings and reboot the device. If
the configured firmware server is found and a new code image is available, the HT502 will
attempt to retrieve the new image files by downloading them into the HT502 ’s SRAM. During this
stage, the HT502’s LEDs will blink until the checking/downloading process is completed. Upon
verification of checksum, the new code image will then be saved into the Flash. If
TFTP/HTTP/HTTPS fails for any reason (e.g. TFTP/HTTP/HTTPS server is not responding, there
are no code image files available for upgrade, or checksum test fails, etc), the HT502 will stop the
TFTP/HTTP/HTTPS process and simply boot using the existing code image in the flash.
Firmware upgrade may take as long as 15 to 30 minutes over Internet, or just 5 minutes if it is
performed on a LAN.
It is recommended to conduct firmware upgrade in a controlled LAN
environment if possible. For users who do not have a local firmware upgrade server,
Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware upgrade.

CONFIGURATION FILE DOWNLOAD
Grandstream SIP Device can be configured via Web Interface as well as via Configuration File through
TFTP or HTTP/HTTPS. “Config Server Path” is the TFTP or HTTP/HTTPS server path for configuration
file. It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can
be same or different from the “Firmware Server Path”.
A configuration parameter is associated with each particular field in the web configuration page.
parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric
numbers. i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page. For a
detailed parameter list, please refer to the corresponding firmware release configuration template.
When a Grandstream device boots up or reboots, it will issue a request for a configuration XML file

named "cfgxxxxxxxxxxxx.xml" followed by a file named "cfgxxxxxxxxxxxx", where "xxxxxxxxxxxx" is the
MAC address of the device, i.e., "cfg000b820102ab". The configuration file name should be in lower case
letters.
For more details on XML provisioning, please refer to:
http://www.grandstream.com/general/gs_provisioning_guide_public.pdf
FIRMWARE AND CONFIGURATION FILE PREFIX AND POSTFIX
Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and
Postfix. This makes it the possible to store ALL of the firmware with different version in one single
directory. Similarly, Config File Prefix and Postfix allows device to download the configuration file with the
matching Prefix and Postfix. Thus multiple configuration files for the same device can be stored in one
directory.
In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”, the
device will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix.
MANAGING FIRMWARE AND CONFIGURATION FILE DOWNLOAD
When “Automatic Upgrade” is set “Yes, every” the auto check will be done in the minute specified in this
field. If set to “daily at hour (0-23)”, Service Provider can use P193 (Auto Check Interval) to have the
devices do a daily check at the hour set in this field with either Firmware Server or Config Server. If set to
“weekly on day (0-6)” the auto check will be done in the day specified in this field. This allows the device
periodically check if there are any new changes need to be taken on a scheduled time. By defining
different intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration
File download in minutes to reduce the Firmware or Provisioning Server load at any given time.
