I am getting a "488 Not Acceptable Here" from my PJSIP application when the caller sends a second INVITE request. I have put breakpoints at the callbacks of my code and they do not get called when the request arrives. Below are the SIP messages: Initial Invite: INVITE sip:11015434001 at 172.25.53.92:5060 SIP/2.0 To: <sip:11015434001 at 172.25.53.92> From: "Agent 9" <sip:1009@172.23.74.54>;tag=snl_L5KQCRbPEj Call-ID: SEC11-44a17ac-44b17ac-1-t4i4ZZEk3IGL CSeq: 1235 INVITE Contact: <sip:1009 at 172.23.74.54:5060;maddr=172.23.74.54> Via: SIP/2.0/UDP 172.23.74.54:5060;branch=z9hG4bKSEC-44a17ac-44b17ac-1-b0blO67CJ3 Accept-Language: en;q=0.0 Alert-Info:<Bellcore-dr1> Allow: REGISTER, INVITE, ACK, BYE, CANCEL, NOTIFY, REFER, INFO P-Asserted-Identity: "Agent 9" <sip:1009 at 172.23.74.54> Supported: timer Date: Tue, 01 Nov 2011 19:45:48 GMT Max-Forwards: 69 Content-Type: application/sdp Content-Length: 289 v=0 o=MxSIP 0 53993236 IN IP4 172.23.74.100 s=SIP Call c=IN IP4 172.23.74.100 t=0 0 m=audio 5010 RTP/AVP 0 8 18 101 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:18 G729/8000 a=rtpmap:101 telephone-event/8000 a=silenceSupp:off - - - - a=fmtp:18 annexb=no a=fmtp:101 0-15SIP/2.0 200 OK Via: SIP/2.0/UDP 172.23.74.54:5060;received=172.23.74.54;branch=z9hG4bKSEC-44a17ac-44b17ac-1-b0blO67CJ3 Call-ID: SEC11-44a17ac-44b17ac-1-t4i4ZZEk3IGL From: "Agent 9" <sip:1009@172.23.74.54>;tag=snl_L5KQCRbPEj To: <sip:11015434001 at 172.25.53.92>;tag=Lq8Ky21ENaWJaCCdAtdNAa1Fd.kK8Ta9 CSeq: 1235 INVITE Contact: <sip:172.25.53.92:5060> Allow: PRACK, INVITE, ACK, BYE, CANCEL, UPDATE Supported: replaces, 100rel, timer Content-Type: application/sdp Content-Length: 210 v=0 o=pjsip-siprtp 3529165547 3529165548 IN IP4 mbpdeb s=pjsip c=IN IP4 172.25.53.92 t=0 0 m=audio 4000 RTP/AVP 0 121 a=rtpmap:0 PCMU/8000 a=sendrecv a=rtpmap:121 telephone-event/8000 a=fmtp:121 0-15 Response: Re-Invite: INVITE sip:172.25.53.92:5060 SIP/2.0 To: <sip:11015434001 at 172.25.53.92>;tag=Lq8Ky21ENaWJaCCdAtdNAa1Fd.kK8Ta9 From: "Agent 9" <sip:1009@172.23.74.54>;tag=snl_L5KQCRbPEj Call-ID: SEC11-44a17ac-44b17ac-1-t4i4ZZEk3IGL CSeq: 1236 INVITE Contact: <sip:189*12147 at 172.23.74.54:5060;maddr=172.23.74.54>;isfocus Via: SIP/2.0/UDP 172.23.74.54:5060;branch=z9hG4bKSEC-44a17ac-44b17ac-1-J0bMn816tg Accept-Language: en;q=0.0 Allow: REGISTER, INVITE, ACK, BYE, CANCEL, NOTIFY, REFER, INFO P-Asserted-Identity: "Agent 9" <sip:1009 at 172.23.74.54> Supported: timer Date: Tue, 01 Nov 2011 19:45:54 GMT Max-Forwards: 69 Content-Type: application/sdp Content-Length: 374 Allow-Events: conference v=0 o=- 2271596941 2271596941 IN IP4 172.23.74.71 s=MS-Ver.33.5.10.1-990 c=IN IP4 172.23.74.71 t=0 0 m=audio 20016 RTP/AVP 0 8 18 101 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:18 G729/8000 a=rtpmap:101 telephone-event/8000 m=audio 0 RTP/AVP 0 8 18 101 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:18 G729/8000 a=rtpmap:101 telephone-event/8000 Am I missing something on the initialization? I do not see how it can be anything else since my code is not being called. Note: I originally tried this on v1.10, but these are from v2.0-alpha2. Thomas G.
