I have many BCM50s networked using VoIP. Centralized voicemail works great for all aspects of VoIP. The problem I have encountered is getting it to work when someone calls a BCM from the PSTN. The call comes in fine, rings four times fine, and then forwards to voicemail fine. However, it forwards to voicemail as if to check a mail box ("enter mailbox number") instead of to leave a message. This sort of makes sense to me because these lines ring on multiple phones so which mailbox should the message be put in. Obviously, I am missing something because I am sure there is a way to make it go to a particular mailbox. I can not just do a forward because it is not considered internal across the WAN.
