straight away I can think of a scenario that would cause a problem. If
I supply toll free numbers that need to be billed for incoming calls
and that can be forwarded out to billable destinations then I want a
CDR for both ends of the bridge.

In your first blind transfer example what if the initial incoming call
to A is billable? I can't see any easy way to get the duration of that
call leg.
