WP820 User Guide
Version 1.0.5.5
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 particular 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:

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.
