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

skroesen1 · ‎03-23-2009

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?
