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 :
 

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
