Hey all,
I have an asterisk box configured as a voicemail application server in our primary MetaSwitch that isn’t receiving MWI.
In previous versions of chan_sip.c, I could make changes that allowed unsolicited MWI SIP Notify messages to be sent to the MetaSwitch, but variations of the code changes in newer versions of chan_sip (I’m on 1.4.13) don’t have the same effect.
Here are the changes I used previously, from voip-info.org:

/* Send MWI */Is there a better way to get Asterisk to send unsolicited MWI Notifications to the MetaSwitch?
There are some other suggestions regarding fromdomain, fromuser, the mailbox= line which is set, etc., but without some code changes like above, the SIP dialog still shows the user as Unknown in the From header which breaks MWI for the MetaSwitch.
It seems like I just need the created SIP Notify to include the voicemail extension in the From field but nothing I try gets it in there - it is always ‘Unknown’.
Any suggestions? I appreciate any tips/pointers.
