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🡪Maintenance🡪 Web Access page.

For a detailed parameter list, please refer to the corresponding firmware release configuration template in the following link:

When the handset 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:
