[SR-Users] Making media packets associated with calls appear unidirectional using rtpproxy and kamailio

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
