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

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.

Hello
I 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 ???
