Port Calculation for CUE 7.1 and later

Common error message:

CUE8-0-1# show license status application
voicemail disabled, ivr session quantity (8) is equal to or exceeds
available ports (8)
ivr enabled: 8 sessions

IVR sessions reduce the number of sessions available for VM.
VM Sessions = Ports minus IVR Sessions.
If Ports = 8 and IVR Sessions = 8 then VM Sessions = 0

Majority of the users do not use IVR features so you may not install and/or activate an IVR license.

CUE# license activate ?
  ivr               Activate IVR feature license
  ports             Activate CUE/IVR ports license
  voicemail         Activate CUE voicemail feature license

Please issue 'license activate ivr sessions N' where N should be 0, 2,
or 4 or 6 so that voicemail will get 8-N sessions, then issue 'reload'.
