----------------------------------------

             Summary: PJSIP channel driver sometimes sends 481 Call/Transaction Does Not Exist
                 Key: ASTERISK-26490
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26490
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 13.11.2
         Environment: Linux 4.4.19-1-pve #1 SMP x86_64 x86_64 x86_64 GNU/Linux

            Reporter: Juris Breicis
            Severity: Critical
         Attachments: MSS_SIP_TRACE_ISSUES.txt

In this particular setup asterisk 13.11.2 is connected to NSN MSS through SIP trunk. The calls are received and routed back through the same trunk. Randomly the PJSIP will reply 481 Call/Transaction Does Not Exist to the trunk's CANCEL request of ongoing call in Ringing state. And sometimes (for no apparent reason) it just processes CANCEL request as expected.
I have attached console dump with: 
core set debug 10 
core set verbose 10
pjsip set logging on

and corresponding sections of pjsip.conf and extensions.conf
