Provisioning and 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, HTTP or 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 field in the web configuration page. A parameter
consists of a Capital letter P and 1 to 5 (could be extended to more in the future) digit numeric numbers.
i.e., P2 is associated with the "Admin Password" in the Web GUI→System Settings→Security
Settings→User Info Management page. For a detailed parameter list, please refer to the corresponding
firmware release configuration template in the following link:
http://www.grandstream.com/support/tools
When the WP820 boots up, it will issue TFTP or HTTP(S) request to download a configuration XML file
named "cfgxxxxxxxxxxxx" followed by "cfgxxxxxxxxxxxx.xml", where "xxxxxxxxxxxx" is the MAC address
of the phone, i.e., "cfg000b820102ab" and "cfg000b820102ab.xml". If downloading "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.
For more details on XML provisioning, please refer to the following document:
