Hi, we have CUCM6.1 and Unity4.2, I have one question about the VM and here is the details:
Phone A (5111) and B (5112) all setup the VM, the incoming call will be diverted to VM if no one pick up the call on phone B, the caller can hear 'Sorry, xx is not available, please leave a message ...' . But if I forward all the calls from phone A to B with B's internal number 5112, the incoming call will be diverted to B's VM, but system message will be different 'Cisco unity system,, ' and the caller can't leave the message. If I use phone B's full DID in CFwdALL number, everything is working fine. Looks like the Unity treats the incoming call base on the caller number in different way.
Any ideas or doc could guide me to fix this problem?
