             Summary: PJSIP: re-INVITE after answering results in wrong stream direction of first call leg
                 Key: ASTERISK-30184
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30184
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Applications/app_dial, Channels/chan_pjsip, Resources/res_pjsip
    Affects Versions: 18.13.0
            Reporter: Maximilian Fridrich


Using the Dial application, when the outgoing call leg receives a 200 from the callee answering the call, and then immediately after receives a re-INVITE from the callee updating a media stream direction, Asterisk does not correctly update the media stream of the first call leg (to the caller). Asterisk does send multiple re-INVITES to the first call leg but the last one does not contain the correct stream directions from the re-INVITE.

When sending the re-INVITE with some delay (e.g. 500ms), Asterisk correctly updates the stream direction of the first call leg (see attached traces).
