CONFIGURATION FILE DOWNLOAD
Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File
(binary or XML) through TFTP or HTTP/HTTPS. The "Config Server Path" is the TFTP or HTTP/HTTPS
server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format.
The "Config Server Path" can be the same or different from the "Firmware Server Path".
A configuration parameter is associated with each particular field in the web configuration page. A
parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric
numbers. i.e., P2 is associated with the "Admin Password" in the Web GUI->Maintenance->Web/Telnet
Access page. For a detailed parameter list, please refer to the corresponding firmware release
configuration template.
When GXP2120/GXP2110/GXP2100/GXP14xx boots up, it will send TFTP or HTTP/HTTPS requests to
download configuration files, “cfg000b82xxxxxx” and“cfg000b82xxxxxx.xml”, where “000b82xxxxxx” is the
MAC address of the phone. If the download of “cfgxxxxxxxxxxxx.xml” is not successful, phone will issue
request for a generic configuration file “cfg.xml”. Configuration file name should be in lower case letters.
