Yes, it looks like for some reason all of my messages got queued and flowed in late yesterday (looks like something to do with the use of reply all and having additional recipients?), so despite realizing the answer after sending, the messages hit hours later.

I think you are mistaken here. The Contact in the 300 should not be used.
Sent from mobile, apologies for brevity and errors.
ο»Ώ
This is the contact in your 300:
sip:service@10.20.0.3:5060?P-Asserted-Identity=%2216001%22%3Csip%3A16001%3Bverstat%3DTN-Validation-Passed%4010.20.0.2%3A5060%3E
This is the URI in your ACK:
sip:1@10.20.20.1:5060
It looks like you're using SIPp which is a pain this way. Rather than coding the URI into the ACK of your SIPp scenario, add
rss="true" to the recv line for your 300, and then use
[next_url] in the template for your ACK mesasge.

Hi !
I have the exact same issue as Alexis. This is my SIP flow (which I believe must be very similar, if not identical, to Alexis' ):

Does your 3xx message have a Contact, and does that Contact URI match the RURI in your 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");
}
β¦
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. buf=0x7f4c44f9d680: SIP/2.0 3..., shmem=0x7f4c3fce7900: SIP/2.0 3

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;
}
