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; } }

either it comes too late and invite transaction does not exist, or it has something wrong in the headers? Can you paste the invite-200ok-ack sip trace of such situation?
Cheers, Daniel
