Bugs: ASTERISK-23106
    https://issues.asterisk.org/jira/browse/ASTERISK-23106


Repository: Asterisk


Description
-------

In NAT scenarios where a call is placed to a Grandstream phone, res_pjsip will sometimes send the ACK to a 200 OK to the private address of the device behind the NAT instead of the address of the NAT device. This corrects that behavior by rewriting the address in the Contact header in the incoming 200 OK and the dialog's target address if necessary (since it has already been rewritten to the incorrect private address).
