   This is sometimes called block blocking. It allows callers and callees
   (rather than the phone company) to decide for themselves,
   case-by-case, what information will be exchanged.

This is possible today using a special Caller ID unit.  Here's something I
snipped from comp.dcom.telecom for when I have more money to spend.  It's not
a real high priority, since I have yet to get a Blocked call (what are the
CID blocking rules in NJ?)

	You want to differentiate incoming blocked calls and also want
to block all of yours automatically when you dial out.  What are you
going to do ... reject incoming blocked calls when all of yours are
blocked?  Maybe I'm reading to much into that request but it sounds
pretty lame.  That's one reason why I block ALL blocked calls and
NEVER block my outgoing calls.

	I've got a "Caller ID * 370" by Colonial Data Technologies.
Sears sells them.  Stores up to 94 numbers and can "block" blocked
numbers.  When a blocked call comes through, it plays back a message
saying this number doesn't accept blocked calls (optional, controlled
from front panel).  Will store/display names and/or numbers.  Has
English and Spanish displays.  Tracks whether the call was answered or
not.  Will dial a displayed number back.  Three line display gives
name (if available) number, date, time, status (new, repeat, answered,
etc...), and sequence number in memory.  Front panel buttons scroll up
and down through memory, switch privacy-block, remove numbers, and
dial numbers.  The dial button supports local vs long distance,
including an added 1 in front of selected calls within your area code.

	Only bitch I've got about it, is when the number doesn't come
in clean.  All it says is "Error".  Most of the time there is enough
information good that you can still tell who it is.  This thing won't
display it though.  Earlier displays and my ClassMate 10's give me
whatever they were able to receive.  Most of the time I can still
figure it out at a glance.  On this box, the "error" display was
STUPID, and was the WORST POSSIBLE MISTAKE they could possibly make.
But I still enjoy playing with it.

	Now what we need is a box that will allow you to program in
numbers to individually block.  Let's see, CLID service then has the
same capacity as "Call Trace", "Return Dial", and "Call Blocking.
Plus you still get to see what's been going on!  Lovely ... in most
places, CLID is the most expensive CLASS feature available.  Till you
look at what it does and what it replaces!

	Disclaimer ... I've no interest in this thing other than
having one and feeling it's a great techie toy!  :-) :-)

	What gets displayed depends on what is sent by the telco.  My
ClassMate 10's are pretty DUMB devices (simple 1200 baud RX only
chips).  I see what the telco sends on the line, and that's generally
what the displays put up.  Blocked calls come in "PRIVATE call" and
calls from switches not supporting CLID come in "OUT OF AREA".
