I was able to send the BYE to the call by adding a parameter in the dialog
module to timeout the dialog with a short time letting the announcement
play, and added the create_dialog with the flag of B to send BYE on dialog
timeout at the beginning of the route. Now that the transactions are
working correctly, I can use the same route for the calls with SDP as well
and tighten up the script. Thanks for helping out with some code examples,
and letting me update on my progress on this thread. Hopefully this can
help someone else out having a similar problem when trying to use Opensips
with RTPENGINE as an announcement server.
modparam("dialog", "default_timeout", 12)
route["RTPENGINE"]{
if (has_body("application/sdp")) {
create_dialog("B");
rtpengine_offer();
$json(reply) := $rtpquery;
$var(port)=$json_pretty(reply/tags/$ft/medias[0]/streams[0]/local
port);
$var(addr)=$json_pretty(reply/tags/$ft/medias[0]/streams[0]/local
address);
remove_body_part();
append_to_reply("Contact:<sip:$rU@
$socket_in(ip):$socket_in(port)>\r\n");
append_to_reply("Content-Type: application/sdp\r\n");
$var(body) = $(rb{re.subst,/(IP4.).*/\1$var(addr)/g});
$var(body) = $(var(body){re.subst,/(audio.)...../\1$var(port)/g});
t_reply_with_body(200, "OK", $var(body));
rtpengine_play_media("call-id=$ci from-tag=$ft
file=/etc/rtpengine/unk_num.wav");
exit;
} else {
create_dialog("B");
$var(newbody) = ("v=0\r\no=Opensips " + $Ts + " 0 IN IP4 " +
$socket_in(ip) + "\r\ns=-\r\nc=IN IP4 " + $socket_in(ip) + "\r\nt=0

PCMU/8000\r\na=rtpmap:101 telephone-event/8000\r\na=fmtp:101 0-15\r\n");
rtpengine_offer("from-tag=$ft replace-session-connection
trust-address replace-origin codec-strip-g729",,$var(body),$var(newbody));
$json(reply) := $rtpquery;
$var(port)=$json_pretty(reply/tags/$ft/medias[0]/streams[0]/local

$var(addr)=$json_pretty(reply/tags/$ft/medias[0]/streams[0]/local
address);
append_to_reply("Contact:<sip:$rU@

append_to_reply("Content-Type: application/sdp\r\n");
$var(body) = $(var(body){re.subst,/(audio.)...../\1$var(port)/g});
t_reply_with_body(200, "OK", $var(body));

exit;
}
}
Thank you.
