fix_nated_contact() function. OpenSer is supposed to change Contact header, but
it only changes it in the INVITE message, but not in the OK response. As a
consequence, ACK messages contain sip:test@192.168.1.1:5060 and not the public
ip. OpenSer doesn’t know how to handle that ACK and forward it to
192.168.1.1:5060.<o:p></o:p></span></font></p>
