I have a cisco callmanager express with integrated voicemail system. Infact everything was working fine when the system was setup.
The problem now is when transfering calls from one phone to the other, it takes more than 10 seconds and also voice mail on some extension has stop working.
What could be the problem for the system to take more than 10 seconds when transfering calls?.
How long does the callmanager Express takes to tranfer calls from one IP phone to the other by default?
I would be very gratefull if sombody can help troubleshoot this problem.
