Re: [Kamailio-Users] What is wrong with this NOTIFY packet

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. =========================== NOTIFY sip:1111111@arzoo.com <mailto:sip%3A1111111@arzoo.com> SIP/2.0 Max-Forwards: 10 Record-Route: <sip:172.18.100.74;lr;nat=yes> Via: SIP/2.0/UDP 172.18.100.74;branch=z9hG4bK3c3.e1003f03.0 Via: SIP/2.0/UDP 127.0.0.1:45382;received=172.18.100.73;branch=z9hG4bK.4f83530d;rport=45382;alias Via: SIP/2.0/UDP 172.18.100.73:5060 <http://172.18.100.73:5060> From: <sip:111@arzoo.com <mailto:sip%3A111@arzoo.com>> To: <sip:1111111@arzoo.com <mailto:sip%3A1111111@arzoo.com>> Contact: <sip:1111111@arzoo.com <mailto:sip%3A1111111@arzoo.com>> Call-ID: 4d61cf9e505d40e905032a18329d61ec(a)172.19.100.42 <mailto:4d61cf9e505d40e905032a18329d61ec@172.19.100.42> CSeq: 1 NOTIFY User-Agent: VoiceMail Event: message-summary Content-Type: application/simple-message-summary Content-Length: 39 =========================== SIP/2.0 415 Unacceptable Content-Type Via: SIP/2.0/UDP 172.18.100.74;branch=z9hG4bK3c3.02003f03.0 Via: SIP/2.0/UDP 127.0.0.1:43416;received=172.18.100.73;branch=z9hG4bK.7be73901;rport=43416;alias Via: SIP/2.0/UDP 172.18.100.73:5060 <http://172.18.100.73:5060> Record-Route: <sip:172.18.100.74;lr;nat=yes> From: <sip:111@arzoo.com <mailto:sip%3A111@arzoo.com>> To: <sip:1111111@arzoo.com <mailto:sip%3A1111111@arzoo.com>>;tag=3c6ba3e4a93d6864 Call-ID: 4d61cf9e505d40e905032a18329d61ec(a)172.19.100.42 <mailto:4d61cf9e505d40e905032a18329d61ec@172.19.100.42> CSeq: 1 NOTIFY User-Agent: Grandstream GXP2000 1.1.4.14 Accept: application/sdp, application/simple-message-summary, application/octet-stream, application/dialog-info+xml, application/pidf+xml, message/sipfrag;version=2.0 Content-Length: 0 =========================== Please guide me in right direction to get rid of 'Unacceptable Content-Type' problem.
