[Kamailio-Users] Having problems using RTPProxy to bridge internal/external networks

[Örn Arnarson]

I got it working by using Klaus's flags;

    if ($ruri =~ "10\.252\.*") {
        force_send_socket("10.252.1.8");
        force_rtp_proxy("ocfaie");

The SDP is correctly re-written and rtpproxy bridges the stream.

Regards,
Örn
