Hi Group,
I know this issue has to do bit more with SIP and off from kamailio
problems, but just wanted to know your opinions on this.
I have my sip extensions registered to kamilio and Asterisk works as a
voicemail server.
Now to implement MWI i send NOTIFY packet from Asterisk to Kamailio and from
kamailio to SIP extension (Grandstream GXP2000).
here is the packet that travels from kamailio to extension and the response
sent from extension to kamilio.
===========================

problem.
