                According to the RFC, in RR header can be IP or FQDN
                (any kind of SIP URI). Even more, the best practice is
                to actually use IPs in RR to be 100% sure that the
                following requests to hit exactly the same box (if using
                FQDN, subject to DNS resolving, a different IP may be
                lookup up later).<br>
                <br>
                If you really want to put an IP there, use the
                record_route_preset() function:<br>
