                <div>Imagine simplest proxy setup - OpenSIPS just

                  replies and so on.</div>

                <div>If I'm doing a 'fix_nated_contact()' before sending
                  this packet I'm expecting Contact: field to be
                  replaced with a source IP:port as per manual. And this
                  works if the Contact is in simple form like '<a href="http://sip:7777777@192.168.29.106:65033" target="_blank">sip:7777777@192.168.29.106:65033</a>'.</div>
                <div><br>

                <div>But if following Contact comes in OpenSIPS doesn't
                  change it leaving private IP in the contact:</div>
