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; } } ------------------------------------------------------------------------ Windows Live™ Hotmail®: Chat.
