Configuring MWI
There are two MWI types:
• Solicited—The SIP UA has subscribed to a voice mail server during registration and can receive
NOTIFY messages from the server without sending SUBSCRIBE messages.
• Unsolicited—The SIP UA needs to subscribe to a voice mail server by sending SUBSCRIBE
messages before it can receive NOTIFY messages from the server.
If MWI is configured for one phone number in different voice entities, only the voice entity with the lowest
number can successfully subscribe to the voice mail server.
Enabling MWI
A voice entity bound to a voice interface can send SUBSCRIBE messages only after you enable MWI for
the voice interface.
