Saving the Configuration Changes
After user makes a change to the configuration, press the “Update” button in the Configuration Menu. The web browser will
then display a message window to confirm saved changes.
Grandstream recommends reboot or power cycle the gateway after saving changes.
Rebooting from Remote
Press the “Reboot” button at the bottom of the configuration menu to reboot the phone 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 GXW42XX can be automatically configured from a central provisioning system.
When GXW42XX boots up, it will send TFTP or HTTP/HTTPS requests to download configuration files, “cfg000b82xxxxxx” and
“cfg00082xxxxxx.xml”, where “000b82xxxxxx” is the LAN MAC address of the GXW42XX . If the download of
“cfgxxxxxxxxxxxx.xml” is not successful, the provision program will issue request a generic configuration file “cfg.xml”.
Configuration file name should be in lower case letters.
The configuration data can be downloaded via TFTP or HTTP/HTTPS from the central server. A service provider or an
enterprise with large deployment of GXW42XX can easily manage the configuration and service provisioning of individual
devices remotely from a central server.
Grandstream provides a central provisioning system GAPS (Grandstream Automated Provisioning System) 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
