GXW42xx User Manual
Version 1.0.15.30
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 customer’s TFTP or HTTP/HTTPS server for
further provisioning.
Grandstream also provides configuration tools (Windows and Linux/Unix version) to facilitate the task of
generating device configuration files. The Grandstream configuration tools are free to end users. The
configuration tools and configuration templates are available for download from
http://www.grandstream.com/support/tools .
