Hello!
In the configuration below Kamailio Proxy creates a transaction for the SIP PUBLISH to get info from the HTTP server in async mode.
But before creating a transaction, a synthetic 200 OK is sent, so that I need somehow to drop the real 200 OK from the upstream Presence Server.
If drop 200 OK in reply_route, tm module starts to retransmit.
Those it is necessary that the 200 OK be consumed by the tm module, but does not go further.
if ( !is_method("PUBLISH") ) {
sl_send_reply("200", "Ok");
t_newtran();
$http_req(suspend) = 1;
http_async_query("$var(url)", "CALLBACK");
}
route[CALLBACK] {
<some header manipulation>
t_on_reply("PUBLISH_REPLY");
route(RELAY);
exit;
}
onreply_route[PUBLISH_REPLY] {
if ( t_check_status("200") ) {
drop; # Does not work!!!
}
}
Any advice is appreciated
