BYE notification in CAFE

Hi all,

I have a question about what happens when a communication, let's say a simple two-party call, is ended by caller/callee. If I understand correctly, the corresponding BYE message is sent directly from caller to callee, i.e. not via a central server, unless this has been specified as routing information in the SIP header upon invitation. Is there a way in CAFE to make sure that the BYE message does travel via the central server? I need this in order to enable the server to do some bookkeeping after each call. The ParticipantEvent.Type.LEFT seems to be no help, as methods triggering on this event type are not executed with me in case of a two-party call.

Thanks,
Ralf
