             Summary: PJSIP will occasional crash asterisk
                 Key: ASTERISK-27887
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27887
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 13.18.5
         Environment: Ubuntu 16.04.4 LTS
Linux 4.4.0-119-generic

            Reporter: art


I save outgoing sipcallid of PJSIP channel with following dialplan:

exten => _+X.,n,Dial(PJSIP/1000@$1.2.3.4,,b(set-callidpvt^s^1))

[set-callidpvt]
exten => s,1,NoOp(Set callidpvt)
same => n,Set(MASTER_CHANNEL(CDR(sipcallidpvt))=${CHANNEL(pjsip,call-id)})
same => n,Return()

This crashes asterisk about once in a week in system with 45000 calls per day. Backtrace shows:

My guess is that outgoing pjsip channel is closed/destroyed by some reason before channel sipcallid is read.
