Making media packets associated with calls appear unidirectional using rtpproxy and kamailio - sr-users

31 Dec 2014

Hi,

I'm trying use two instances of rtpproxy listening to two different public
IPs, to handle incoming and outgoing legs.

That means i want to implement this network topology:

SipClient--------->media from client to proxy--->rtpproxy1
Sipclient<----------media from proxy to client<---rtpproxy2

Where rtpproxy1 listening to IP1
and rtpproxy2 listening to IP2

in kamailio cfg :
 modparam("rtpproxy", "rtpproxy_sock", " udp:127.0.0.1:22222
udp:
127.0.0.1:22223")

if (is_request()) {
                if (!has_totag()) {
                        add_rr_param(";nat=yes");
                }
                rtpproxy_offer("IP1");
        }
        if (is_reply()) {
                if(isbflagset(FLB_NATB)) {
                        fix_nated_contact();
                }
                rtpproxy_answer("IP2");
        }

But its not working.

Thanks in advance
