The usual way is that the address of the Voice Mail Server has to be configured in the user's phone. The user phone needs to send SUBSCRIBE for message-summary event and the Voice Mail Server will NOTIFY the user if there is a change in his mailbox.
The presence engine is responsible for collecting and distributing "presence" information: event "presence". I don't understand why you want to use presence engine to collect and distribute MWI. Unless, you have some framework like Presence Engine that work for message-summary event too. On 9/3/07, Sai P.
