GW0221 User Manual

upgrade, remote reboot, etc.
Van Access provides a licensed provisioning system called TAPS that can be used to support
automated configuration of GW0221. To enable this feature on the GW0221, a user just needs to
enter the IP address of the TAPS server in the TFTP server field of the configuration screen, or enter
the HTTP provisioning Server URL in the HTTP Upgrade Server field. Then reboot the GW0221.
For details on how TAPS works, please refer to the documentation of TAPS product.
7 SOFTWARE UPGRADE
To upgrade software, GW0221 can be configured with an HTTP server where the new upgrade file is
located. For example, following URL in the HTTP Upgrade Server:
http://firmware.myVoIPService.com:6688/GATE102/upgrade
Where firmware.myVoIPService.com is the FQDN of the HTTP server, “:6688” is the TCP port the
HTTP server is accessing, “/GW0221/upgrade” is the RELATIVE directory to the root directory in HTTP
server. Thus, you can put different firmware into different directory as well.
Note: To enable HTTP firmware upgrade, “Auto Upgrade” field has to be set to “Yes”. In addition,
the VOIP ADAPTER will check the HTTP server in the number of days that is defined in “Check for new
firmware every__ days” field.
8 KNOWN LIMITATIONS WITH GW0221
Old PBX / Telephone Switch
If the PSTN line that is connected the “Line” port of the GW0221 comes from a PBX or telephone
switch, and the *00 feature is used to make PSTN calls, once you hang up, the GW0221 may not
immediately go back to VoIP mode. The reason is that the PBX or telephone switch continues to
send PSTN signals to the GW0221 after the call has been disconnected. This may happen with older
model PBXs / telephone switches.
Device Hanging
Occasionally, the GW0221 may permanently lose its connection with the SIP proxy server or hang.
To initiate connection, simply power off and then power on the GW0221. The reason for the device
“getting stuck” varies including gatekeeper settings, internal LAN / network connectivity problems,
etc.
