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

             Summary: Segfault in ast_senddigit_end using PJSIP
                 Key: ASTERISK-28086
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-28086
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 13.19.0
         Environment: Gentoo (physical), Debian (AWS)
            Reporter: Jeremiah Gadd


It appears there may be a race condition in which PJSIP attempts to end the sending of a DTMF tone after a bridge is destroyed, causing PJSIP to try to send to a non-existent channel.

I'm happy to post as much of the core dumps as needed, I could not find a way to attach them to this report.
