We are due to start an upgrade from CallManager 3.3.3 to 4.2. I was thinking of taking the opportunity to upgrade Unity Voicemail 4.0 to 4.2 at the same time but would now like to postpone it to a later date. One change at a time is probably sensible. Will we run into any compatibility issues using Unity 4.0 with CallManager 4.2 ?
Re: Is Unity 4.0 compatible with CallManager 4.2 ?
Just looked at the first link.
It seems I have to be running Cisco Unity-CM TSP 8.1(1) or later for CallManager 4.2 compatibility with Unity 4.0(1) if I have SCCP endpoints. Any idea how I can check if this the case and also check the TSP version number ?
