How to set up a Cisco IP phone model 7911 for Asterisk?

Question

Asterisk

Good evening. Please tell me if the Asterisk version is critical for the Cisco 7911 SIP firmware. So far I haven’t found the answer on Google, maybe one of you has come across these devices for PBX systems based on Asterisk. At the moment, I tested on the basis of AsteriskNow, Elastix, FreePBX, none of the indicated Asterisk servers could connect clients based on Cisco 7911 in itself. What suggestions can you offer?

Answer 1

The version is not critical, the correct non-trivial setting of the 7911 and dhcp/tftp/etc configuration file is critical

Answer 2

The version is not important.
Get the address via dhpc for the phone, then the web interface specifies the login and password with which it will register at the +/- proxy station, depending on the settings of the station.
