We are currently upgrading our phone system from call manager 9.1 to 10.5. During this we have discovered that a particular conference phone model (CP-7936) is no longer able to use any soft keys function when the device is off hook (hold\transfer\conference). When the phone is on hook, all the soft keys work (corp directory \ phone book). The phone model works properly once added back to the 9.1 call manager with no unusual configuration (tested with several 7936) and i have compared the 9.1 configuration with our 10.5 to ensure nothing was accidently selected.
Current phone config information:
App Load ID: 7936.3-3-21-0 (shows to be most recent version)
SW Version: 3.3(21.00.0003)
