Hi,

What might be the cause that t_check_trans() function fails and ACK message is not being routed?
This is a simple SIP to SIP call.



         if ( is_method("ACK") )
         {
            if ( t_check_trans() )
            {
               # non loose-route, but stateful ACK; must be an ACK after a 487 or e.g. 404 from upstream server
               t_relay();
               exit;
            }
            else
            {
               # ACK without matching transaction ... ignore and discard.\n");
               exit;
            }
         }
