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.
I haven’t had very much success with these phones and Asterisk in SIP mode. However, they work well using SCCP. Take a look at this SCCP module for Asterisk.
I just configured a 7016 module successfully. You need the firmware for the add-on module and then in the SEP.cnf.xml file, you add this after the tag:
<addOnModules> <addOnModule idx="1"> <loadInformation>B016-1-0-4-2"</loadInformation> </addOnModule> </addOnModules>
Then, in the
<sipLines> node, you add entries such as this one for the keys you want to configure:
<line button="9"> <featureID>21</featureID> <featureLabel>Joe Bloggs</featureLabel> <speedDialNumber>4000</speedDialNumber> <featureOptionMask>1</featureOptionMask> </line>
Then, update your device with this configuration file and firmware using the TFTP process and it should work out fine.
Hope this works for you!
