I read about this in a magazine a while ago.  After pondering the
question of receiving calls for a few days I came up with the
following possible solution:

Each phone comprises telephone AND pager, with an LCD display.  An
incoming call is handled by paging the phone with the number of the
caller.  This can be automated by Caller-ID.  The owner of the CT2
phone then finds a Phonepoint and tells the phone to call the number
which the pager function received.  OR, the pager displays an
'incoming call' message, possibly with ID, and the user moves to a
Phonepoint to accept the call.  Callers would have to be warned that
it may take a couple of minutes before the call is answered.  If the
Phonepoint density were high enough, however, it would be workable.
This really boils down to a cellular network with very small cells
which do not overlap at all.

How many channels can the CT2 phone operate on?  This determines the
number of lines available at a given phonepoint, I guess.

Even if the above is not implemented, a combination pager/CT2phone
might interest manufacturers / purchasers of these phones.
