[02:51] 	<fezzae>	2004/11/10 02:51 PST [-] dropcall in state 'SENT_RINGING'
[02:52] 	<fezzae>	but the other side still says 180: Ringing
[02:58] 	<fezzae>	the 'SENT_RINGING' state isn't handled
[02:58] 	*	fezzae adds it to the 'SENT_INVITE' tuple and sees
[02:58] 	<`anthony>	not sure whether you're meant to send back a BYE or a CANCEL in that state.
[03:00] 	<fezzae>	ah.
