<p>Apparently the t_realy() stopped script execution (by
returning 0) when e2e ACK forwarding was successful. The
patch should change that to return true.</p>
<p>If all works fine while testing, then I will backport.</p>

Hello
<div>I've tried mhomed = 1 with no luck - not so
sure what you mean by default route, I've added
listen = udp:myadsress:5060<br>
<div>I also have auto_aliases=no and
alias=myaddress</div>
<div><br>
</div>
<div>However, what bugs me is that execution
seems to stop INSIDE t_relay and the info

<div>Hello</div>
<div>I am using kamailio 5.0.2, on a
debian 9 system.</div>
<div><br>
</div>
<div>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).</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Here is the snippet from
route(relay)</div>
<div><br>
</div>
<div>
<div>
xlog("L_INFO","route(relay) @@ $rm
- Source: $si:$sp, fu:$fu, tu:$tu\n"
);</div>
<div>
$var(restrelay)=t_relay();</div>
<div>
xlog("L_INFO","route(relay) @@ $rm
- t_relay result: $var(restrelay)"
);</div>
<div> if (!$var(restrelay)) {</div>
</div>
<div><br>
</div>
<div>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</div>
