             Summary: res_pjsip: Deadlock in T.38 framehook
                 Key: ASTERISK-26974
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26974
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip_t38
    Affects Versions: 13.15.0
            Reporter: Richard Mudgett


A deadlock can happen while T.38 is active and a re-INVITE happens.  The thread processing the re-INVITE is trying to update the channel's format capabilities while the channel thread is trying to send a frame.  The thread processing the re-INVITE has the session's media container lock and wants the channel lock and the channel thread has the channel lock and wants the session's media container lock.
