I've installed Kamailio on multi NIC server (192.168.1.0 &amp; 172.16.1.0), and I've configured rtpproxy in bridged mode in order to manage RTP but I've some trouble during call between endpoint placed on different network.<div><br></div><div>I've find an example regarding Kamailio+RTP in IPv4+IPv6..it's a good point to start but i can't use "af" function... I've tried to replace it with $si but only some call works.</div><div><br></div><div>How can i replace af correctly? Is there any example conf for my scenario?</div><div><br></div><div>Many thanks</div>
