I just tested and works fine. Try with master branch and default config file.
To test I modified a bit the default kamailio.cfg and I have in route[RELAY]:
xlog("=======* request $rm before relay\n");
if (!t_relay()) {
xlog("=======x request $rm not relayed\n");
sl_reply_error();
}
xlog("=======> request $rm relayed\n");I get the ACK routed and in logs I get:
{1 2 ACK 1473723014@127.0.0.1} 2(20129) ERROR: <script>: =======* request ACK before relay
{1 2 ACK 1473723014@127.0.0.1} 2(20129) ERROR: <script>: =======> request ACK relayedCheers,

Many thanks for your help.I've applied the patch, recompiled and I see no difference unfortunately. The ACK is not forwarded, and execution after t_relay stops.
I've set the debug level to 4 and captured the traces - I believe the section dealing with the ACK is there: https://pastebin.com/TG03YQWC

Hello,
can you give a try with latest master branch or by using the patch from next link?
- https://github.com/kamailio/ka
mailio/commit/52111974b4571e05 62e8e731df80f48dbc504915 Apparently the t_realy() stopped script execution (by returning 0) when e2e ACK forwarding was successful. The patch should change that to return true.
If all works fine while testing, then I will backport.
Cheers,
Daniel

Hello
I've tried mhomed = 1 with no luck - not so sure what you mean by default route, I've added listen = udp:myadsress:5060
I also have auto_aliases=no and alias=myaddress
However, what bugs me is that execution seems to stop INSIDE t_relay and the info message after the t_relay is not displayed.
I hate to say this, but could this be a bug ?

Check that your installation have one NIC with only one default route on host.If not check that "mhomed=1" is enabled.

HelloI am using kamailio 5.0.2, on a debian 9 system.
Everything was running fine, until one of our voip provider changed his switch. Our kamailio is relaying between several voip providers and several asterisk (only the signalisation, no rtp).
When we get an invite from this new switch, we select an asterisk and relay it correctly to this box. However, the OK is relayed back. But when the voip providers sends an ACK for this OK, the t_relay function does not return at all, it just dies with no action and no error.
Here is the snippet from route(relay)
xlog("L_INFO","route(relay) @@ $rm - Source: $si:$sp, fu:$fu, tu:$tu\n" );$var(restrelay)=t_relay();xlog("L_INFO","route(relay) @@ $rm - t_relay result: $var(restrelay)" );if (!$var(restrelay)) {
When processing the initial invite, I do get both INFO messages. When the ACK is processed, I only get one INFO message, and no ACK is relayed - so it seems execution dies in the t_relay
What could be wrong ???
J.
Details of the ACK:
ACK sip:dialednumber@kamailioIP:5060 SIP/2.0
