We seem to have encountered a race condition between a CANCEL and a 200 OK. The result of this
is a call stuck in sipxBridge causing phantom calls every two hours (session timeout). In the attached trace.xml, port 5560 is our application. It cancels the outgoing call a few milliseconds before the called party answers the call and the sipxProxy receives the 200 OK. But despite sipxProxy receiving and acknowledging the CANCEL, it continues to process the 200 OK. But no ACK is sent back to the SIP trunk, The SIP trunk repeats the 200 OK several times. Eventually sipxBridge is stuck in a re-INIVITE every session timeout state. Anyone seen this. Any solutions?
