Hello,

if the 200ok is consumed by tm, it will destroy the transaction very soon. I am not sure this is a good path to go.

If you need to stop the retransmission, a 100 trying should be sent instead of 200ok. Can you reconfigure the next hop to do that? Or is it out of your control?

Cheers,
Daniel

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
