[comp.dcom.telecom] Criticism of Call Forwarding

Miguel_Cruz@ub.cc.umich.edu (09/27/89)

Two things about call forwarding:

A) Why on earth does it do that thing where the first time you try
forwarding, it actually places the call to the number, and if it's
busy or no answer, you have to do the whole forwarding sequence again?
Is there a single person on the planet for whom that's helpful or
convenient?

B) How difficult would it be to modify the system so that when one
placed a call to a forwarded number, they would first hear a short
tone signifying that the call was being bumped?  Unlike A), that would
actually be informative and helpful.

Miguel_Cruz@ub.cc.umich.edu

[Moderator's Note: Regards (A), if you actually reach the party to whom
you are forwarding, you are assured of dialing correctly. If you get a
busy or no answer, it might be because you dialed a wrong number. By doing
it a second time, telco is assured that your instructions match your
intentions. Without this repeat-dialing verification, you might accidentally
have forwarded to the wrong place. Regards (B), many people do not want
you to know they are not at home/office, etc. They'd prefer that you assume
they are wherever you dialed them at. And for residences, do you want to
let a burglar know you are not home, due a 'forwarding tone' which tells
him there is no one there to receive a call (or unauthorized visit)?  At
present, if you listen *closely* when dialing a centrex number with call
forwarding on no answer, after the third ring you will hear a slightly out
of synch ring the fourth time. PT]

Here's another criticism:

If I don't have call forwarding, is there any way for me to turn OFF the
call forwarding that someone else has directed to my number? As the
recipient of such forwarded calls, I should have the right to reject
the "honor" of receiving them.

Is there a way to prevent my number from ever being specified as the
recipient of call-forwarded calls? (Something like the UNIX "mesg n"
command but in the telco universe... :-)

And, as a side question: I seem to recall this being asked during the
"Caller*ID" debate, but don't recall it being answered. Maybe somebody
out there with Caller*ID can now tell us: If a call is call-forwarded to
a phone with "Caller*ID", is the number displayed that of the forwarding
phone or the originating one?

If the number displayed is that of the originating phone, is there any
heirarchy of displays -- that is, if the originating phone is out of the
area and the number isn't available, but the number of the forwarding
phone IS available, will the forwarding-phone's number be displayed in
that case?

Regards, Will

The problem with call-forwarding is that SOMEONE should know the
call has been call-forwarded; otherwise the conversation can be
very awkward.  I agree with the moderator that letting the caller
know that the call has been forwarded will defeat one of the selling
points of that feature, but if the receipients aren't aware that
the call they're getting is forwarded, they may accidentally give
away that information through their fumbling.  If the receipients
got a coded ring, then they would be forewarned (e.g., if the person
who set up call forwarding was in their home, that person could
answer the phone; if your relative or friend forwarded to you while
you were on vacation, you would know when you answered where you were
supposed to pretend you're at).

In an office, this would be even more useful.  Before desktop
terminals became the standard, and terminal rooms were the norm,
people who would be working at terminals for several hours would
often call-forward to the terminal room.  When they forgot to
remove call-forwarding, the person who picked up the phone in the
terminal room would often just say that so&so wasn't there, or
that this wasn't that person's phone (the latter would also
happen if calls were left forwarded to someone else's desk, because
you knew you would be in their office for a long time).  At
least with a coded ring, there would be no puzzlement to receipients
as to why callers apparently got a wrong number.

Huh.  I always thought it was a slimebag method to get more revenue.  To
set up call-forwarding, you need to make (and, if applicable, pay for)
a call, like it or not.  (Well, an alternative is to place two calls,
hanging up before either is answered, not exactly to the delight of whomever
you're forwarding the calls to.)  Patrick's remarks are valid (I appreciate
that it would be a drag to be the recipient of erroneously forwarded calls),
but we endure several inconveniences the way things are.  There are times
when you'd like to be able to set up call-forwarding without ringing the
recipient's phone (3 A.M., for example).

P.S.  I once wanted to forward my phone to a 976 service as a joke, but
      the switch wouldn't let me.  It did, however, let me forward to an
      identical 976 service in an adjacent area code (at a greater cost
      to me for each call forwarded, of course).

	With all this talk about non-ergonomic rings, I thought I would
bring up another mis-feature.  Our ATT System-25 at work doesn't have call
forwarding, it has what we've come to refer to as call following.  To
trnasfer your calls to another phone, you have to go to that phone (known
in the S25 manual as a "voice terminal") and do some magic there.  To
cancel the feature, you have to also do some magic at the remote phone.  It
works, but it's the reverse of the way people have been trained to think.
I can't figure out why ATT decided to do it this way.

The originating one.

No.  You always get the originating phone.  Thus, if the originator is
out of area, but the forwarder is in area, caller*id shows "out of area".

More Caller*ID tidbits: It is possible for the little Caller*ID unit
to not even notice that a call came in if you pick up the phone very
shortly after the first ring.  This is because the Caller*ID info gets
transmitted between rings, and it is possible to pick up before any
info gets sent.  This is pretty annoying.

Also, not all exchanges in the same town will be in area.  We have
seven phone lines in my house on five different exchanges, all in the
same town.  (It's a long story, but it sure is fun having a 25-pair
block in the basement installed by NJ Bell).  Calls from two of the
exchanges show up as "out of area", even though they are from the next
room.  Bleah!

I don't know if this is true everywhere, but in New Jersey, the
Caller*Id-equipped recipient of a forwarded call gets the caller's
number, not the forwarder's number.  If the caller is "Out of Area"
then that is displayed; even if the forwarder is not.

I tried to take advantage of this a few weeks ago.  Our modems kept
getting calls from somone/something that would disconnect after
listening to our answer tone for several seconds.  These calls
always arrived two at a time, followed by two more about 30 minutes
later.  I waited until the first of a series of two arrived, and
then forwarded the modem line to our Caller*Id-equipped voice line.
But alas, when the second call arrived, the display showed "Out of
Area" (even though the forwarding was intra-office) so I still
couldn't identify the caller.  But it didn't sound like a person or
an open mic when I answered the voice line.

System-25 does it that way because Horizon(tm) did it that way.
That, in fact, explains most of the System-25 feature set.

No, I don't know exactly why Horizon did it that way, but it may be
related to their "floating phone number" feature.  You can have
phone numbers in your Horizon or System 25 which do not correspond
to real telephone sets (or voice terminals, for that matter!).  If
you are a fast-mover around your office, you may be without a
physical set, but you can have a floating extension (called a PDC or
personal dial code, in System-25 speak).  You can then "log in" your
floating PDC at the nearest real telephone set, and receive your
calls there, until you log out or log in at some other voice
terminal.   Call-following is just a special case of logging in a
PDC (but in this case, not a floating PDC) on a voice terminal.

[I keep my floating PDC logged into the phone on the boat!]

Boy, would I love to have this feature here at work (CENTREX) and home.
I don't know how many times I ended up in someone's office or home without
expecting to be there and wished my calls were forwarded to me.  Also,
if it is going to take a substantial amount of time to get there, I would
rather my machine take calls till I get where I'm going.   I can also go
office to office and forward my calls as I move.

Of course, I still would want the ability to do both Call Forward from my
office/home phone in addition to Call Follow from any phone.
