Cisco IP phone 7940/7960
I got a couple of Cisco 7940 and 7960 IP phones and tried almost every thing that’s relevant to SIP firmware and Asterisk. Therefore i went through different experience and some issues as well, hopefully those all I will discuss later. For now let’s try to load the SIP firmware on a Cisco 7960 IP phone, also we will configure it’s SIP account with Asterisk PBX. Basically i can’t see any difference between Cisco 7940 and Cisco 7960 except one button but that really doesn’t matter if you are using SIP firmware. If you need Cisco 7960 help or Cisco 7940 help, you are on right place.
Cisco phone often come with SCCP protocol which probably Asterisk doesn’t support. So we need to install SIP firmware on the Cisco phone the latest SIP firmware version is 8.2 but you may have some natting issues there fore 7.4 will be a best option. If you got a new Cisco 7960 phone have SCCP firmware then you can’t install Cisco 7.4 firmware directly, first you will have to load SIP firmware version 6.x then you will upgrade it to 7.4.
