We've had a number of calls disconnect at exactly the two hour mark. Running a trace, I found that the ITSP sent us an INFO, we returned a NOT ALLOWED, and the ITSP responded with a BYE.
If I parse this right, it looks like the INFO was just informational to let us know the call duration and signal quality so far. 1. Was NOT ALLOWED the correct/desired response from sipXecs? 2. Was terminating the call a valid response from the ITSP after receiving the NOT ALLOWED reply? Here is are the three packets in question. There were no SIP packets between these packets. Identifying info has been redacted. At 15:19:44.946, the ITSP sent me an INFO: Time: 2010-11-30T20:19:44.946000Z Frame: 134 /tmp/trace.yFcp6069/_.sipxbridge.trace.xml:302802 Source: ITSPIPAddr:5060 Dest: ls-sip1.lynk.com-sipXbridge INFO sip:myphonenum...@sipxecsipaddr:5080;transport=udp<sip:6165324...@192.168.9.1:5080;transport=udp> SIP/2.0 Via: SIP/2.0/UDP SipProxyIPAddr:5060;branch=z9hG4bK-d8754z-d145746366dfbc12-1---d8754z-;rport=5060;received=ITSPIPAddr Via: SIP/2.0/UDP ITSPIPAddr:5061;branch=z9hG4bK-vqmzrjdsx3ziootw;rport=5061 Record-Route: <sip:myphonenum...@sipproxyipaddr;lr<sip:6165324...@192.168.9.254;lr>> From: <sip:numberical...@itspipaddr;user=phone>;tag=b6ozx43ypndfo4qp.i To: "sipxbridge" <sip:myphonenum...@sipxecsipaddr>;tag=4094594954750048626 Call-ID: CallID CSeq: 928 INFO Contact: "Anonymous" <sip:SipProxyIPAddr:5060> Max-Forwards: 69 User-Agent: Sippy Cisco-guid: H323ConfID H323-conf-id: H323ConfID Content-Type: application/dtmf-relay Content-Length: 25 Signal=3 Duration=1640 Which my system apparently rejected as NOT ALLOWED at 15:19:44.953: Time: 2010-11-30T20:19:44.953000Z Frame: 135 /tmp/trace.yFcp6069/_.sipxbridge.trace.xml:302833 Source: ls-sip1.lynk.com-sipXbridge Dest: ITSPIPAddr:5060 SIP/2.0 405 Method not allowed Via: SIP/2.0/UDP SipProxyIPAddr:5060;branch=z9hG4bK-d8754z-d145746366dfbc12-1---d8754z-;rport=5060;received=ITSPIPAddr Via: SIP/2.0/UDP ITSPIPAddr:5061;branch=z9hG4bK-vqmzrjdsx3ziootw;rport=5061 From: <sip:numberical...@itspipaddr;user=phone>;tag=b6ozx43ypndfo4qp.i To: "sipxbridge" <sip:myphonenum...@sipxecsipaddr>;tag=4094594954750048626 Call-ID: CallID CSeq: 928 INFO Server: sipXecs/4.2.0 sipXecs/sipxbridge (Linux) Content-Length: 0 The ITSP hung up on me at 15:19:54.954: Time: 2010-11-30T20:19:54.954000Z Frame: 136 /tmp/trace.yFcp6069/_.sipxbridge.trace.xml:302839 Source: ITSPIPAddr:5060 Dest: ls-sip1.lynk.com-sipXbridge BYE sip:myphonenum...@sipxecsipaddr:5080;transport=udp<sip:6165324...@192.168.9.1:5080;transport=udp> SIP/2.0 Via: SIP/2.0/UDP SipProxyIPAddr:5060;branch=z9hG4bK-d8754z-b5e7f1354b9cf838-1---d8754z-;rport=5060;received=ITSPIPAddr Via: SIP/2.0/UDP ITSPIPAddr:5061;branch=z9hG4bK-cqtg4sgjt7pwslve;rport=5061 Record-Route: <sip:myphonenum...@sipproxyipaddr;lr<sip:6165324...@192.168.9.254;lr>> From: <sip:numberical...@itspipaddr;user=phone>;tag=b6ozx43ypndfo4qp.i To: "sipxbridge" <sip:myphonenum...@sipxecsipaddr>;tag=4094594954750048626 Call-ID: CallID CSeq: 929 BYE Contact: "Anonymous" <sip:SipProxyIPAddr:5060> Max-Forwards: 69 User-Agent: Sippy Cisco-guid: H323ConfID H323-conf-id: H323ConfID Content-Length: 0 Mike Burden [cid:image002.gif@01CB960E.548B6080] Lynk Systems, Inc e-mail: m...@lynk.com<mailto:m...@lynk.com> Phone: 616-532-4985
