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, FTP/FTPS or HTTP/HTTPS. The "Config Server Path" is the TFTP,
FTP/FTPS 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 5-digit numeric numbers. i.e., P2 is associated with the
"New Password" in the Web GUI→Maintenance→Web Access page→Admin Password. For a detailed
parameter list, please refer to the corresponding configuration template.
When the GRP2615 boots up or reboots, it will issue a request to download an 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 followed by a
configuration file named "cfgxxxxxxxxxxxx", the phone will issue a request to download a specific model
configuration file "cfgGRP2615.xml". If this file is not available, the phone will issue a request to download
the generic "cfg.xml" file. The configuration file name should be in lower case letters.
