[comp.dcom.telecom] Call*Trace, Call*Block, Caller*ID

You can deal with nuisance calls effectively without revealing phone #'s.
I have Caller*ID (NJ Bell puts the cute asterisk in the name) here in
Morristown, but I can also get Call*Block, which prevents the last caller
from calling me again, and Call*Trace, which sends the last caller's phone
number to the local office.  Neither lets me know the phone number myself.
You don't need black boxes or prior arrangement, of course.

Call*Repeat and Call*Return are amusing: they retry either the last number
I dialed (repeat) or that dialed me (return).  With Caller*ID and a redial
button on the phone, neither of these seem to be any use.  But -- if the
other party is busy, it will keep trying the number for 1/2 hour until it
gets through (my phone's not tied up by this).  I get a distinctive ring
and if I answer it, it will ring the other number.

Because the service coverage is small (some exchanges in NJ, none inter-lata)
and uneven (even some exchanges in Morristown don't work), it's not as useful
as it could be, but I like it anyway.  Now I want to get a computer interface
for my unit and a voice synthesizer so that it will announce who's calling
instead of ringing.

I'm not sure, but I think that NJ Bell will be putting a funny mark in the
White Pages beside any phone number that has Caller*ID.
