NBX SIP MWI code

When the NBX voicemail or 3rd party voicemail receive a new message, it send a code to the phone to trigger a new message alert. What's the code that'ssent to the phone to turn on/off the MWI?

That code is actually a Message waiting Indicator packet ot turn on Mwi and then when the msg is listened to , sends another one to shut it off ....

The Message-Waiting-Indicator SIP event message body is what I am looking for. Basically I use ESNATECH unified communication system as the 3rd party voicemail system for NBX. Now I found MWI doesn't work because the ESNA doesn't know what code to use to send to the NBX.

ESNA and 3com did a lot of work a few years ago to ensure their products work together. Then they were using TAPI to communicate so it would be TAPI sending the MWI messages.
