Hi
You said that only thing changed is the Provider chanded their end.
Have you compared the previous signaling to the current ?
Previous I mean before provider change their switch.
Could there be some difference and that causes this error.

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 ???
J.
