Description (last modified by bennylp)

Scenario (pjsua as UAC):

 pjsua                  UAS
-----------------------------
  INVITE          -->
  200/OK (INVITE) <--
  BYE             -->
  ACK             -->
  200/OK (BYE)    <--
  200/OK (INVITE) <--
  ACK             -->

This scenario happens when the SDP in 200/OK is not acceptable hence pjsua sends BYE to disconnect the call.

Upon sending ACK for the 200/OK retransmission, pjsip incorrectly sets the invite session state back to CONFIRMED after it has been DISCONNECTED, causing assertion and possibly crash.

Thank you Dan Åberg for the report.

To reproduce the error

Sample scenario: pjsua is configured with mandatory SRTP, and the SDP in 200/OK answer doesn't contain valid SRTP description.

  • run pjsua with: 
    --null-audio --local-port 0 --use-srtp 2 --srtp-secure 0
  • run SIPp as UAS with the attached scenario
