[comp.dcom.telecom] Proposal: An Answering Machine I'd Love to Have

coleman@twinsun.com (Mike Coleman) (03/03/90)

Here is a proposal for the "Answering Machine I'd Love to Have":

Motivation

Over half the phone calls I get are "junk".  They're from people I
don't want to talk to: sales droids, wrong numbers, "you've just
won...", etc.  Unfortunately, in our modern world, a phone is a
necessity, so I can't just have mine disconnected.  Like many other
people, I sometimes "rudely" use my answering machine to screen my
calls, but I feel that this is an annoyance put upon me and People I
Wish To Talk To by People I Don't Wish To Talk To.

Solution

My proposed answering machine would work like this: 

1)  Caller rings.

2)  Answering machine picks up.  Plays user message: "You have the
Froboz household.  Please enter your password now.  If you don't have
one and you really need to talk to us, you may stay on the line for 90
seconds, after which you may leave a message with your number and we
will call back as soon as possible."

3)  If caller enters a password (i.e., a touch-tone string), answering
machine takes a user-specified action dependent on the password:

	a) For good password, goto 5 or 6.
	b) For bad password, goto 4, 6, or 7.

4)  If caller doesn't enter a password, play elevator music (or
whatever) for 90 seconds (or some user-specified interval).  Then,
goto step 6.

5)  Ring the users phone in some manner.  This might just be the normal
bell, or it might include a preprogrammed announcement corresponding
to the password (e.g., "It's your Mother.").  Delay 5 (or some
user-specified interval) seconds here.

6)  Take a message.  Depending upon the password entered (or not
entered) the message may be "screened" (i.e., played through a
speaker) allowing user to pick up.  Hang up when done.

7)  Possibly play another message ("Let me tell you how I feel about
obscene callers/telemarketers/child molesters/etc....").  Then hang
up.

This allows people I give passwords to to reach me quickly, and I know
who they are when they call.  Recognition is based on who they are (or
at least, what they know) rather than the specific phone number they
are calling from (if your wife is calling from the airport, for
instance).

People who(m) I may want to talk to, but who don't have passwords,
such as the police, or my bank, may get through to me if they really
have the need (or at least if they are willing to wait 90 seconds to
leave a message).

Obscene callers will probably not wait 90 seconds, and if they do
habitually, this gives me a good head start on a trace.

Sales droids are quite unlikely to wait, and I'm willing to put up
with an occasional message skip on playback.  I can give out my phone
number to banks, etc., without worrying what torrent of sales calls
that might unleash.

Those F!@#$ing autodialers are completely defeated, I think.  Perhaps
I should require the caller to dial 1 at the beginning to indicate
that they are a real person?  (Sound familiar?)

As long as the system has reasonably long passwords and doesn't allow
remote playback or programming, it's pretty secure.

The machine belongs to and is operated by me, rather than the phone
company.  We all know that centralized authority is the root of all
evil.  :-)

I suppose this device would be about as complicated and expensive to
build (and about as easy to use :-( ) as a typical (programmable) VCR.
Still, I'd buy one in a minute.

Any comments?  Does something like this already exist?  Could I
home-brew one with a PC and some magic card?  Is there anything
illegal about this?

[Sidebar: In one of Heinlein's novels, there is a character with a
very interesting "doorbell".  Essentially, it's something like "Insert
$20 into the bill changer to talk to me.  If I decide your visit is
worthwhile, I'll return your money."  In this spirit, would it be
possible (or reasonable) to get a 976 number as a home phone number?

To the person who wishes not to be disturbed, may I recommend the
voice-mail system with a beeper. True, you will be beeped every time
someone calls, but they can't directly bother you because you have to
call everyone back, no matter what. The beeper gives you access to
your messages anytime they get left.

It's not exactly what you want, but it is available in most areas now
for a cheap price.

Sure does. It's called a Watson (I'm beginning to feel like a Watson
shill, but it really is a useful device). Using one of these in
conjunction with either a PBX such as a Panasonic or home Centrex such
as Commstar II, you can have any combination of message taking, call
screening, code-access, or whatever you desire. The limitations are
your imagination. If there's anything illegal about it, I have been
breaking the law for years.

I've worked out a way to have a Watson take major credit cards. You
could have someone enter his Visa or Mastercard number and collect the
twenty dollars that way. Actually, for giving me such a great idea, I
might share with you MY scheme :-) I will definately consider putting
something on mine as a gag if nothing else.

I have a similar problem, which I plan on solving in the near future
with an AT&T Voice Power card in a 3B1 computer.

I currently use the Voice Power board and computer as my answering
machine-- I wrote a software program which effectively simulates a
Phone Mate answering machine, with a few extra features.  I'm
considering updating the software to handle calls using the following
scenario:

1.  Phone rings

2.  Message is played, "You have reached the Widget residence.  If you
are calling from a touch tone telephone, press the '1' key now."

3.  If '1' is pressed now or during step 4, go to step # 7

4.  "We do not accept any calls from solicitors or sales people of any
kind.  If you are one of these individuals, please hang up now.  If
you are not a solicitor and still wish to contact me, please say 'YES'
now."

5.  If 'YES' is detected by voice recognition software within 10 seconds,
go to step # 10

6.  Hang up on caller (no valid response)

7.  "We do not accept any calls from solicitors or sales people of any
kind.  If you are one of these individuals, please hang up now.  If
you are not a solicitor and still wish to contact me enter your code
number or press the '9' key on your phone now"

8.  If the '9' key is pressed within 10 seconds, go to step # 10
    If a password is entered, handle it as a special case of '9', or
    with some kind of voice mail.

9.  Hang up on caller (no response)

10. If 'at home' flag is set on the computer system, signal a 'ring' in
    some undetermined way (note- the 3B1 has no means of providing ring
    voltage, so something will have to be hacked-up to do this)

11. If 'at home' flag is not set, take a standard answering machine message
in the usual way.

If a solicitor or salesperson does complete the call, you may take
down information about the person or yell obscenities at him/her for
being stupid or inconsiderate.

This is only a preliminary dialogue, by the way .. it seems a bit on
the cumbersome side to me, and I'll probably trim it down, but this
one gets the general idea across.

If I do make the software, I will post the program in unix-pc.general.
Those interested in the 'plain 'ole answering machine' program should
note that I'm planning to post the source in unix-pc.general in the
next week or so.

I just purchased an Panasonic Answering Machine that works similar to
what was suggested it is called privacy ring.  There is a password (up
to 3 numeric didgets) that you program.  You then inform your friends,
ect. what the password is.  When they call and get your outgoing
message (OGM) they enter the password and the answering machine will
ring for 30 seconds to give you a chance to answer (You now know it is
someone that you gave the code to).  If you do not answer in 30
seconds it will then give the OGM again they can then leave a message
or enter to password again and continue to ring the answering machine.

It also has many other great features. Includes speaker phone and
conventional phone, speed-dial of 24 numbers, date and time stamp each
message, digital stored OGM, memo message, automatic transfer (calls
another number or beeper with your messages), compact in size, full
voice menu beeper-less control with separate password. Toll saver
(answers after 4 rings first call 2 rings all other calls, when you
call remotely and it doesn't answer after 2 rings you know you have no
messages and hang up thus saving the toll charge).  Memo phone number
(as you are receiving a phone number from information or other party
you may key it in with out you or the other party hearing the tones
and then dial the number with single key stoke after you hang up).
Re-dial last number dialed, flash hook button, combination tone and
pulse dialing.  Wall mountable.  

Callers can skip OGM by pressing * and start recording their message
for you.  As you monitor incoming calls you don't hear your OGM just
their message to you.  Auto answer (you can tell it to automatically
activate speaker phone when phone ring.  You can also remotely turn on
speaker phone (great if your family never answers the phone but you
want your own calls to be answered, they have no choice).  Voice
activated (VOX).  Remote turn-on/turn-off.

And I am still discovering features!  If you want more features then
what this machine offers now you are dreaming!  I do not have the
model number with me but will provide it if anyone is interested.
Cost?  (not cheap I paid $179.97)

Two quibbles : Why should it be illegal? I think it's perfectly valid
to see if you have messages. Why be charged for discovering you have
no messages - when you *do* have them and want to access them, *then*
the telco makes its money. You could extend the same logic to the
practice described by some guys on this list who use exchange callback
to allow internal calls. I guess you'd disapprove of that, too.  

But your other point strikes me as intriguing - you want external
callers to be able to hang up if they figure there's a machine on the
line?  Isn't that the same idea, that the caller gets information
from the number of rings to answering ? Why allow one and not the
other?

I may not be the only person to point this out, but nevertheless here
goes:

In Denmark you are indeed charged for "picking up the phone". The
counter (on which your charges are based) first "clicks" when you lift
the receiver (or more strictly: when you get the dialling tone).

Danish pay-phones have no return slot. Whatever money you put in stays
there.  The argument for all this is that the costly part for the CO
is in the *setting up* of the call; *not* in maintaining it. Even the
fact that the callee does not answer his phone contains information to
the caller.

Needless to say, repeating auto-diallers are not a big sell on the
Danish market  :-)

How about the following scenario.  You decide to go see a friend who
lives some distance away.  You get in your car, drive to a toll road,
get on, and pay when you get off.  You get to your friend's house,
ring the bell, and there is no answer.  You get back in your car,
drive back over the toll road, and ask for the tolls back, since your
friend wasn't home, and you did not get to talk to him.  The toll
collector looks at you, and says: "Are you kidding?  You used my
road!."  Then you go to the gas station, and ask for a fillup, with
the same rationale.  The answer is probably not fit for usenet. Etc.
etc.

While I am certainly not advocating being charged for call attempts,
there definitely is a good rationale for them.  Actually, I believe
that in Denmark there is such a charge.  Some things are free, which
could reasonably have charges.  When buying something in a store, they
will usually let you return it for any reason.  Some businesses will
charge a restocking fee.

Also remember that one COCOT operator recently got caught placing
calls first over AT&T to see if the card number was good, hanging up,
and then placing the call over their own lines.  The court deemed this
illegal.

There was also some serious discussion in CCITT whether there should
be charges for call attempts in ISDN, which the US strongly opposed.

Rich Zellich <zellich@stl-07sima.army.mil> (03/14/90)

Remember also though, that the "toll saver" feature is there for
another purpose as well.  Allowing more rings on the first pickup
gives you, the owner, time to get to the phone to pick it up before
the machine grabs the incoming call.  After the machine gets the first
one, however, it makes the assumption that you aren't home and answers
more quickly on subsequent calls so the caller doesn't have to wait
listening to rings any longer than necessary - theoretically keeping
some people from hanging up too soon.

The above, of course, so you can leave the machine on all the time and
not have to worry about remembering to turn it on every time you
leave.

Hey, the fact that a payphone is not in use (and thus available to the
caller) conveys information.

I think we should charge 'em for looking.  :-)

(Actually, this is a classic case of monopoly despotism.  In a free
market, the issue would be decided by consumer choice.  If company A
charges for every off-hook, then company B can try to knock their
socks off in the marketplace by charging only for completed calls.  I
suspect that in the US, at least, it'd be a winning strategy.)

In the New York City area, there are two cellular telephone service
providers.  When the first system (known to cellular telephone users
as service B) went on the air a few years ago, they charged for every
call attempt, whether or not anyone answered.  The competition
(service A) which became active almost a year later charged only for
completed calls.  Apparently, Tom Neff is correct.  Today, both
companies charge only for completed calls.
