[SIPForum-discussion] voicemail to presence interface

[Peili Xu]

Hi Sai,

RFC3842 defines an event package for Message Summary&Message Waiting
Indication for SIP. Presence Server can subscribe this event from voice mail
system to get the notification.

One way for the user to get MWI is to subscribe directly to the voice mail
system as per rfc3842. But it's also possible for a Presence Server to act
as MWI notification server as long as the Presence Server can get
notifications from the backend MWI engine.
