This is a problem I have been digging into a bit. In my case asterisk 
did not send out the NOTIFY with the header Content-Type: 
"application/simple-message-summary", but with "Content-Type: 
text/plain", so the NOTIFY is treated as a txt message. In result, when 
I pressed the MWI button, I saw the text from asterisk stating the 
amount of messages I have. I changed it to work, and now asterisk calls 
the extension the message is sent from (asterisk at sip-server). After 
calling this the MWI indication disappears, I'm not sure if it also 
disappears after calling from another phone.

I'm using chan_sip2 and I changed some stuff, so I'm not sure if this is 
also a problem with standard chan_sip (the txt vs vm issue).

Kind regards,
