Does your 3xx message have a Contact, and does that Contact URI match the RURI in your
ACK?

Subject: [SR-Users] help on how to get ACK

Hello all, moving just a bit aside of the http and async_http.
After all the real useful and interesting thread on that topic what helped me, im facing a
problem i cant deal with and need a hint at least.
Scenario
INVITE -> Kamailio
on request_route
...
if(is_method("INVITE")){
t_newtran();
http_async_query("http://nuc:8080", "HTTP_REPLY");
}
…
Kamailio -> 100 - Trying
then
route[HTTP_REPLY] {
if ($http_ok) {
xlog("L_INFO", "route[HTTP_REPLY]: status $http_rs\n");
xlog("L_INFO", "route[HTTP_REPLY]: body $http_rb\n");
t_reply(302,"Redirect");
} else {
xlog("L_INFO", "route[HTTP_REPLY]: error $http_err)\n");
}
}
Kamailio -> 302 Redirect
ACK -> Kamailio
This last ACK, how can i read it and use it to terminate the transaction? because Kamailio
keeps transmitting the 302 message 3 more times until the transaction is finished by a
timer
42(44) DEBUG: tm [t_reply.c:1723]: t_retransmit_reply(): reply retransmitted.

42(44) DEBUG: tm [h_table.c:133]: free_cell_helper(): freeing transaction 0x7f4c3fcd35a0
from timer.c:651
in request_route i have
if(is_method("ACK")){
if(!t_check_trans()){
t_release();
}
exit;
}
