7975 Phone and (2) 7916 Expansion Modules only 42 buttons

I have a 7975 phone with (2) 7916 Expansion modules. The modules are 12 buttons each, both with 2 pages making them 24 buttons each. There should be 48 total expansion buttons and 8 on the phone making it 56 for the entire setup. Callmanager only shows 42 buttons total (counting the ones on the phone also) allowing me to only use the first 10 buttons on the first page of the second expansion module. I was running version version 7.0.1.11000-2. TAC had me update to 7.0.1.21007-1 saying this was a known bug and it would resolve it. After the update the problem still exists. A few days later TAC finally gets back saying this is "normal operation" for this version and that I have to wait for the next release. Sounds like I am getting jerked around on this. Anyone experience the same issue and get it resolved?

Hi Steve,


Here are the details for this issue. This has not been fixed in any current 7.x versions.


Cisco Unified Communications Manager 4.2(3)SR3a, 4.3(2), 5.1(3)b, and 6.1(1), 7.0 and 7.1


Total Number of Buttons Supported


Cisco Unified IP Phone 7975G = 42

I believe you are hitting this bug which has only been fixed in certain 6.1(3) versions;

CUCM 6.1.3 Phone Button Template for 7965/7975 Shows 34/36 line.

Symptom:

On CUCM version if you have a 2 7916 extension moduleon7965 and 7975 the Phone Button template is not capable of 42 lines as per Document we can only ad 34/36 respectively.


Conditions:

When you want to add the 2 7916 extension modules to the Ip phone 7965 /7975 Phones we can not make 42 line Phone Button template for those Phones.

Hey Sushil,


You are most welcome buddy! Thanks for the nice vote. This is a weird one, that's for sure ;-)
