You need to mention which RTPProxy set should be used for engage_rtp_proxy,
see below link,
http://www.opensips.org/html/docs/modules/1.7.x/rtpproxy.html#id292702
Also i noticed you are calling engage_rtp_proxy on a Re-INVITE, you should
do it only on the first INVITE of a call, e.g.
if (is_method("INVITE") && !has_totag()) {
engage_rtp_proxy();
}
Thank you.
