I'm using ser 0.10.x ( CVS version). About rtpproxy traffic balancing, I don't know where I have to put rtpproxy IP address and where I have to set $node variable value. How does SER obtain rtpproxy IP address ? What the relation between rtpproxy IP address and N0, N1.....etc ? What parameters have I to put in force_rtp_proxy() function? Only rtpproxy IP address? In my framework happens : when SER receives INVITE Request and 200 OK it rewrites the body of SIP message (SDP). The problem is that it doesn't put in connection information (c) rtpproxy IP address; it puts its IP address. So clients send their RTP packet to SER instead to rtpproxy. How I can force SER to rewrite correctly SDP so that clients receive rtpproxy IP address in INVITE and 200 OK SIP message?
