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

             Summary: SIP/OK response to a SIP/BYE request is sent to the wrong port
                 Key: ASTERISK-23182
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-23182
             Project: Asterisk
          Issue Type: Information Request
      Security Level: None
          Components: Resources/res_pjsip
    Affects Versions: 12.0.0
            Reporter: Marko Seidenglanz
            Severity: Trivial

When a SIP/BYE request is sent to Asterisk it sends it's SIP/OK to the NAT-Port it has received the message from. The problem is, that this message never arrives at the destination:

<--- Received SIP request (414 bytes) from UDP:23.251.129.236:51723 --->

On the other hand when Asterisk responds to a SIP/OK with an SIP/ACK it sends the message to the correct port:
