In SIP, 200-299 are considered the codes for which a recipient accepts the request. Any particular reason for the client to send 493?
Anyhow, the patch to msilo should not big -- change inside function m_tm_callback() from modules/msilo/msilo.c for which code to set the MS_MSG_DONE flag. The SIP response cannot forwarded to initial sending entity, because it lacks appropriate Via headers, but more important it will not have a request generated by that entity. You can have a NOTIFY request generated by kamailio sent to the entity to inform that its message was delivered.
