SIMPLE CONFIGURATION: MEDIA GATEWAY TO ACCESS PSTN NETWORKS

GXW-410xv can be configured to work with any leading SIP server, for a pure media gateway to access

PSTN networks. In such applications, the user only needs to configure GXW-410xvgateway Stage Dialing

field and Sip Server field.

For a simple set-up, users only need to configure a SIP server field for default SIP Profile 1. This field

should be configured to point to the SIP server to be used with the GXW-410xv.

For advanced applications, the user is required to choose at least one SIP server field from the SIP

profiles and one stage dialing under system Channel configuration table. On SIP server sides, the SIP

server must be configured to forward user PSTN calls to the GXW-410xv.

Please be aware that by default, the system uses North American PSTN settings and TWO STAGE

dialing to access PSTN networks for VOIP to PSTN calls and PSTN to VOIP calls. Two stage dialing

means the end-user will hear dial-tone twice. First dial-tone is used to let users to input destination

number in the same network of the calling networks. Second dial-tone is used to let users to input final

destination number.

CONFIGURATION GUIDE

CONFIGURATION WITH WEB BROWSER

The GXW-410xv has an embedded Web server that will respond to HTTP GET/POST requests. It also

has embedded HTML pages that allow a user to configure the IP phone through any common web

browser. Examples of GUI interfaces can be downloaded @

http://www.grandstream.com/GUI/GUI_GXW-410xv.

ACCESSING THE WEB CONFIGURATION MENU

1. Connect the Power to the GXW-410xv unit.

2. Connect an Ethernet cable between the LAN port on GXW-410xv to your PC.

3. You will have to assign a dummy IP with the same subnet as the GXW IP Address, which is

192.168.0.160 by default. So, set an IP address like 192.168.0.x for your PC.

4. Launch web browser and type http://192.168.0.160 at address of web browser. This connects you

to the GXW-410xv web server.

You may choose to use DHCP or PPPoE connection or another static IP address according to your local

network environment.

The Gateway Web Configuration Menu can be then accessed by the following URI: http://Gateway-IP-

Address where the Gateway-IP-Address is the IP address of the Gateway.

NOTE: To access the configuration page, type the GXW IP address into the browser, stripping out the

leading “0” because the browser will parse in octet. e.g. if the IP address is: 192.168.001.014, please

type in: 192.168.1.14.

TABLE 11: GRANDSTREAM CONFIGURATION PAGE DEFINITIONS

Activate Profile When set to Yes the SIP Profile is activated.

Profile Name A name to identify a Profile.

SIP Server SIP Server’s IP address or Domain name provided by VoIP service provider.

Outbound Proxy IP address or Domain name of Outbound Proxy, or Media Gateway, or Session

Border Controller. Used by GXW-410xv for firewall or NAT penetration in different

network environments. If symmetric NAT is detected, STUN will not work and

ONLY outbound proxy can correct the problem.

Use DNS SRV: Default is No. If set to Yes the client will use DNS SRV to look up server.

User ID is Phone

Number

If the GXW-410xv has an assigned PSTN telephone number, this field should be

set to “Yes”. Otherwise, set it to “No”. If “Yes” is set, a “user=phone” parameter will

be attached to the “From” header in SIP request.

SIP Registration This parameter controls whether the GXW-410xv needs to send REGISTER

messages to the proxy server. The default setting is “Yes”.

Unregister on

Reboot

Default is No. If set to yes, the SIP user’s registration information will be cleared on

reboot.

Expiration

This parameter allows the user to specify the time frequency (in minutes) for the

GXW-410xv to refresh its registration with the specified registrar. The default

interval is 60 minutes (or 1 hour). The maximum interval is 65535 minutes (about

45 days).

Local SIP port This parameter defines the local SIP port the GXW-410xv will listen and transmit.

The default value for Account 1 is 5060. It is 5062, 5064, 5066 for Account 2,

Account 3 and Account 4 respectively.

NAT Traversal This parameter defines whether the GXW-410xv NAT traversal mechanism will be

activated or not. If activated (by choosing “Yes”) and a STUN server is also

specified, then the GXW-410xv will behave according to the STUN client

specification. Under this mode, the embedded STUN client inside the GXW-410xv

will attempt to detect if and what type of firewall/NAT it is sitting behind through

communication with the specified STUN server. If the detected NAT is a Full Cone,

Restricted Cone, or a Port-Restricted Cone, the GXW-410xv will attempt to use its

mapped public IP address and port in all of its SIP and SDP messages. If the NAT

Traversal field is set to “Yes” with no specified STUN server, the GXW-410xv will

periodically (every 20 seconds or so) send a blank UDP packet (with no payload

data) to the SIP server to keep the “hole” on the NAT open.

Proxy-Require SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.

Early Dial Default is No. Use only if proxy supports 484 response.

Session

Expiration

Grandstream implemented SIP Session Timer. The session timer extension

enables SIP sessions to be periodically “refreshed” via a SIP request (UPDATE, or

re-INVITE. Once the session interval expires, if there is no refresh via a UPDATE or

re-INVITE message, the session will be terminated. Session Expiration is the time

(in seconds) at which the session is considered timed out, if no successful session

refresh transaction occurs beforehand. The default value is 180 seconds.

Grandstream Networks, Inc. GXW-410xv User’s Manual Page 18 of 30

Firmware 1.0.0.36 Updated: 11/2006

Min-SE The minimum session expiration (in seconds). The default value is 90 seconds.

Caller Request

Timer

If selecting “Yes” the phone will use session timer when it makes outbound calls if

remote party supports session timer.

Callee Request

Timer

If selecting “Yes” the phone will use session timer when it receives inbound calls

with session timer request.

Force Timer If selecting “Yes” the phone will use session timer even if the remote party does not

support this feature. Selecting “No” will allow the phone to enable session timer only

when the remote party support this feature. To turn off Session Timer, select “No”

for Caller Request Timer, Callee Request Timer, and Force Timer.

UAC Specify

Refresher

As a Caller, select UAC to use the phone as the refresher, or UAS to use the Callee

or proxy server as the refresher.

UAS Specify

Refresher

As a Callee, select UAC to use caller or proxy server as the refresher, or UAS to

use the phone as the refresher.

Force INVITE Session Timer can be refreshed using INVITE method or UPDATE method. Select

“Yes” to use INVITE method to refresh the session timer.

Enable 100rel The use of the PRACK (Provisional Acknowledgment) method enables reliability to

be offered to SIP provisional responses (1xx series). This is very important if PSTN

inter-networking is to be supported. A user’s request to use reliable provisional

responses is invoked by the 100rel tag which is appended to the value of the

required header of initial signalling messages.

Send

Anonymous

If this parameter is set to “Yes”, the “From” header in outgoing INVITE message will

be set to anonymous, essentially blocking the Caller ID from displaying.

Preferred

Vocoder

The GXW-410xv supports up to 5 different Vocoder types including G.711 A-/U-law,

GSM, G.723.1, G.729A/B. The user can configure Vocoders in a preference list

that will be included with the same preference order in SDP message. The first

Vocoder in this list can be entered by choosing the appropriate option in “Choice 1”.

Similarly, the last Vocoder in this list can be entered by choosing the appropriate

option in “Choice 8”.

FIRMWARE UPGRADE

Our latest official release can be downloaded from: http://www.grandstream.com/y-firmware.htm.

Firmware (or software) upgrades can be done either via TFTP or HTTP. The corresponding configuration

settings are on the configuration page. End users should NOT touch the configuration settings that are

useful for ITSPs. To upgrade your unit firmware, follow these steps:

1. Under Advanced Settings webpage, enter your TFTP or HTTP Server IP address (or FQDN) next

to the “Firmware Upgrade: Upgrade Server” field.

2. Select via TFTP or HTTP accordingly.

3. If you plan to use Automatic Upgrade, set it to “Yes”, otherwise No (this will make it check for

upgrade every time you reboot).

UPGRADE THROUGH HTTP

To upgrade firmware via HTTP, the field “Firmware Upgrade and Provisioning: Upgrade Via” needs to be

set to HTTP. The “Firmware Server Path” should be set to where the firmware files are located.

For example, the user can use the following URL in the Firmware Server Path:

firmware.mycompany.com: 6688/Grandstream/1.0.0.29 where firmware.mycompany.com is the FQDN of

the HTTP server. It can also be in IP address format. “:6688” is the TCP port the HTTP server listening to,

default http server listens to port 80. “/Grandstream/1.0.0.29” is the RELATIVE directory to the root dir on

HTTP web server.

Grandstream Networks, Inc. GXW-410xv User’s Manual Page 22 of 30

Firmware 1.0.0.36 Updated: 11/2006

UPGRADE THROUGH TFTP

To upgrade firmware via TFTP, set the field “Firmware Upgrade and Provisioning: Upgrade Via” to TFTP.

The TFTP server can be configured in either IP address format or FQDN.

To configure the TFTP server via the Web configuration interface, follow these five steps:

1. Open your browser to input the IP address of the GXW-410xv.

2. Enter the admin password to enter the configuration screen.

3. Enter the TFTP server address or URL in the “Firmware Server Path” field near the

bottom of the configuration screen.

4. Once the “Firmware Server Path” is set, update the change by clicking the “Update”

button.

5. Reboot or power cycle the unit.

If the configured updating server is found and a new code image is available, the GXW-410xv will retrieve

the new image files by downloading them into the GXW-410xv’s SRAM. During this stage, the GXW-

410xv’s LED will blink until the checking/downloading process is completed. Upon verification of

checksum, the new code image will be saved into the Flash. If TFTP fails for any reason (e.g., TFTP

server is not responding, there are no code image files available for upgrade, or checksum test fails, etc),

the GXW-410xv will stop the TFTP process and simply boot using the existing code image in the flash.

Firmware upgrading may take as long as 20 minutes over the Internet, or just 20+ seconds if it is

performed on a LAN. Grandstream recommends conducting firmware upgrades in a controlled LAN

environment if possible.

NO LOCAL TFTP SERVER

For users who do not have a local TFTP server, Grandstream provides a NAT-friendly TFTP server on

the public Internet for users to download the latest firmware upgrade automatically. Please check the

Services section of Grandstream’s Web site to obtain this TFTP server IP address. Alternatively, user

can download and install a free TFTP or HTTP server in his LAN for a firmware upgrade.

A free Windows version TFTP server can be downloaded from:

http://support.solarwinds.net/updates/New-customerFree.cfm.

Directions For Downloading TFTP Server:

1. Unzip the file and put all of the files under the root directory of the TFTP server.

2. Put the PC running the TFTP server and the GXW–410x in the same LAN segment.

3. Go to File -> Configure -> Security to change the TFTP server's default setting from "Receive

Only" to "Transmit Only" for the firmware upgrade.

4. Start the TFTP server, in the phone’s web configuration page.

5. Configure the Firmware Server Path with the IP address of the PC.

6. Update the change and reboot the unit.

You can also download the free HTTP server from http://httpd.apache.org/ or just use Microsoft IIS web.
