Hi, If you are using dispatcher module or similar, then the bottle-neck is not Kamailio, but Freeswitch. I guess, Kamailio simply doesn't get any answer from the AS and thus replies with an error as no AS is available. Kamailio by default/minimal configuration won't send any errors, it depends on your configuration.
