> When my ITSP tries to send a (SIP SIMPLE) MESSAGE event to my Asterisk machine, Asterisk responds with {{SIP/2.0 481 Call/Transaction Does Not Exist}} which doesn't really make any sense to me for a single/one-off event like a MESSAGE event.  MESSAGE events don't seem to involve "transactions" which must exist.
