             Summary: res_pjsip can't handle endpoints behind NAT
                 Key: ASTERISK-22941
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22941
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip
    Affects Versions: 12.0.0
            Reporter: Leif Madsen


Trying to use res_pjsip today on Asterisk 12 (public interface) with devices behind NAT. First issue was lack of documentation for devices behind NAT. Once we got that far, we ran into an issue where the ACK response that Asterisk was sending for the received 200 OK after an INVITE was going to the private IP of the device, rather than the address listed in the AOR list.

Configuration:
