[OpenSIPS-Users] RTPProxy + OpenSIPS 1.7 Integration

[Nick Khamis]

Hello Everyone,

I am having trouble getting the RTPProxy 1.2.0 to work with OpenISP 1.7.

Starting the proxy using:
./rtpproxy -s udp:127.0.0.1:12221 -l public/private -p
/var/run/rtpproxy.pid -u root root -F -d INFO LOG_LOCAL0

opensips.cf relevant pieces

modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:12221")
modparam("rtpproxy", "rtpproxy_autobridge", 1)
modparam("rtpproxy", "rtpproxy_timeout", "0.5")
modparam("rtpproxy", "rtpproxy_retr", 3)

if (has_totag() && is_method("INVITE")) {
		engage_rtp_proxy("ie");
}
if (is_method("ACK") && has_body("application/sdp")) {
	rtpproxy_answer();
}

route[1] {
	xlog("Enter route 1");

	if (has_body("application/sdp")) rtpproxy_answer();

	if (is_method("INVITE")) {
		xlog("New Call for route [ fu=$fu/ tu=$tu /ru=$ru/ ci=$ci]");

		if (rtpproxy_offer()) {
		        t_on_reply("1");
		}
		else {
		    t_on_reply("2");
		}

	
		t_on_branch("2");
		t_on_failure("1");
	}

	if (!t_relay()) {
		sl_reply_error();
	}		

	exit;
}

onreply_route[1] {
	xlog("incoming reply\n");
	if (has_body("application/sdp")) rtpproxy_answer();
	exit;
}

onreply_route[2] {
	xlog("incoming reply\n");
	if (has_body("application/sdp")) rtpproxy_offer();
	exit;
}

When starting OpenSIPS everything looks fine:

Making a call howver, yields the following error (watch it work now ;):

ERROR:rtpproxy:force_rtp_proxy_body: no available proxies
