I had installed a new Unity 4.0(4) in a old CCM cluster 3.3(5)
I have configured Unity but I below detail the problem:
I can leave vm in the cisco phones but I cannot hear anythinq when I dial the voice pilot number in the cisco phone. The status monitor of Unity display the vm port busy when I dialled the voice pilot number but the phone didn?t receive packet.(only send it)
In the CCM the ip address of the vm ports are 164.x.x.x (arpa). Is it normal?.
I cleanned arpa table with arp -d* in the unity and ccm servers
but I obtained the same fault 164.x.x.x the voice mail port in the CCM . I rebuilt the vm ports with the same result
And I resetted the unity server later
Check your TSP versions. YOu may need to update teh TSPs on 4.04 to a new version. There seems to be issues with TSps in older version that are similar to this problem you are having.
