Notification of implicit bridge teardowns

 

The January 19th, 2007 CCXML Working Draft is not very clear on how
implicit bridge teardowns resulting from a <join> should be handled.
Section 10.4.1 shows all of the possible outcomes of a <join> tag.  Some
of these examples require a full or partial teardown of an existing
bridge.  The spec does not state if a 'conference.unjoined' event should
be generated when this occurs.  It does state in section 10.6.14 that if
a connection is dropped (as in a merge, disconnect, etc.), then the
appropriate 'conference.unjoined' event(s) should be sent.  It may be an
easy assumption that ANY implicit bridge teardowns should result in a
'conference.unjoined' event, but what about partial teardowns?  It
starts to get a little more complicated there.  Is it enough to just
update the connection state variables when bridges change as a result of
a <join>?
