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 "New Password" in the Web GUI->Maintenance->Web/SSH
Access page->Admin Password. For a detailed parameter list, please refer to the corresponding firmware
release configuration template.
When the HT81X boots up or reboots, it will send a request to download a file named
"cfgxxxxxxxxxxxx”followed by a configuration XML file named "cfgxxxxxxxxxxxx.xml", where
"xxxxxxxxxxxx" is the MAC address of the phone, i.e., "cfg000b820102ab" and "cfg000b820102ab.xml". If
the download of "cfgxxxxxxxxxxxx.xml" file is not successful, the provision program will download a
generic cfg.xml file. The configuration file name should be in lower case letters.
