CM 5.1.1 upgrade 7931


I bought 7931G phones for the Call Manager 5.1.1, but i got surprised when i tried to add, because de model didn't appear, so i proceed to find the Firmware and I found that cmterm-7931-sccp.8-3-1.cop.sgn.

I followed the instructions and I upgraded the firmware (, but when I tried tu add again this model type, it didn't appear. I restarted the CM, but it didn't work.

Is somebody know how to add this model type in a CM 5.1.1?

Re: CM 5.1.1 upgrade 7931

Unfortunately the 7931 phone will not be supported in UCM until 6.0(1). The 7931 was developed for CME to start since they are a true key system replacement, however we could have used 7931 support in Call Manager 4.1. :)

Here are the release notes on the 7931 only supporting Call Manager 6.0

Cisco Unified IP Phone 7931G Support

Cisco Unified Communications Manager release 6.0 and later supports Cisco Unified IP Phone 7931G. The Cisco Unified IP Phone 7931G is designed to meet the needs of businesses with moderate telephone traffic and specific call requirements. The Cisco Unified IP Phone 7931G supports IEEE 802.3af Power over Ethernet, security, and other calling features. Dedicated hold, redial, and transfer keys facilitate call handling. Illuminated mute and speakerphone keys give a clear indication of speaker status.
