I would appreciate some help configuring my Cisco IP Phone 7975. In fact the phone works well with the SIP firmware (version SIP75.8-4-1ES2) and an Asterisk Server. Now I would like to connect a Cisco IP Phone 7916 Expansion Module to it. The problem is during my search on the web I have only found explanations to configure the expansion with a Cisco Unified Call Manager but not with Asterisk.
For information, the IP Phone gets its configuration file from a tftp server and the file follows the SEP.cnf.xml format.
So if someone here have already done this task before, can he pleases explain me.
Thanks in advance for your help.
