Hi,
Simply for this to work
1. create your auto attendant pilot
2. create your subscriber [user voicemail]
3. configure the forward settings for the user line and associate him the VM profile
4. create an incoming dial-peer that direct to the AA pilot with a session target to your call manager
5. From CUE web page determine the operator extension for timeout cases
6. finally confirm your ports CSS can reach your users partitions
I think it should be work like that or please post you conf if any error still exist
wish this be helpful
thanks
