CONFIGURATION THROUGH A CENTRAL SERVER

Grandstream GXW40XX can be automatically configured from a central provisioning system.
When GXW40XX 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
GXW40XX. 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 GXW40XX can easily manage the configuration and
service provisioning of individual devices remotely from a central server.
