My daughter wants a new DCT phone and would like caller identification. Been
reading up and it appears that many types of calls do not display the
caller. Is this a fact?

Do they only display names where the number and name has been programmed in
(like with a mobile?) or do they display all numbers?

Is it reliable?

My cordless phones display all UK landline and mobile numbers unless they're
withheld. If a caller from foreignland is trying to scam me/get me to buy a
mobile phone it says "out of area".

You're lucky.

Most networks are incapable of telling the difference
between "customer withheld" and "lost somewhere
by the network".

We get an irregular alternation of "Out of area", "Withheld",
and "Unavailable" when the mother-in-law phones from Belgorod
(Russia-Ukraine border). Can't see any pattern to why it gives each
message.

The system allows for the use of 'presentation' numers
instead of the real number. A displayed 0845 number
will be the one that has been deliberately presented to
you, as no-one actually dials out from an 0845 number.

This system is used by corporates who want all of
their outgoing calls presented as coming from
the one number. This is so that people don't ring
back to the outgoing operator who just happens
to be sitting at the desk that your call came from

The only information sent by the phone company is the phone number or a code
to indicate the number is "unavailable", "withheld" etc. Your phone, will
then look through its own address book and try to match the incoming number
with a name. If it finds a match then it displays the name. If no match is
found then it displays the number. So they work just like a mobile phone
would.

With BT, when presented by the caller the telephone number is
displayed. If the number is withheld then 'Withheld' is displayed. Most
junk calls that I get now come from aboard and the display just shows
'International'.

My display unit can display names but this is a function of my own
equipment changing programmed numbers to names.

My BT phone shows "Private" rather than "witheld " but that might be down to my
Binatone cordless phone setup. .Otherwise either numbers are shown or the name
of the caller if it is my phone's Memory

For me that's quite useful. If I get an international call displayed on
the unit, I pick up the handset and *wait* until the other caller speaks
before making any sound.

If it is a genuine international call I will respond, if it is a
'congratulations, you have won blah..' tape i will drop, if it is
silence I will hold until they cut off (10 seconds or so off *their*
phone bill)

If you make a sound when you pick up the call, then the calling centre
routes the call to a human who you really don't want to talk to.

I let the answerphone respond to these 'international' calls.
Unfortunately these *******s have a habit of using an automated message
to fill up the message space in the answerphone. I've recently had six
calls in the space of half an hour all leaving a two minute repeating
message ' Congratulations you have won ..............just phone this
(premium rate?) number to claim your prize"

I don't say anything until the reciever is at my ear for all calls. If
there is no background noise, just silence, I don't say anything. What
happens next depends on the mood I'm in. Sometimes I wait the 10 seconds
or so until the call centers equipment finally finds a free operator and
connects me to them. I then only say "hello" a few seconds after each
time they have finished speaking. Other times I just place the reciever
next to me and carry on with what ever I was doing, ignoring the little
voice saying "hello? hello?". Can take quite a long time before they give
up, Iike this one as if the CCO is trying to talk to me they aren't
annoying someone else.

If you make a sound when you pick up the call, then the calling centre
routes the call to a human who you really don't want to talk to.

I don't think that happens. Silent calls are just the call centre kit
dialing calls before there is an operator free to take the call the
moment it is answered (if it is). Having a CCO not talking to someone
costs money.

I must be plagued with different operators than you ;-)

I get a few of these a month, and previously when I have said "hello" an
operator has either responded back, or the line drops immediately. Now I
say nothing and wait for someone to make the first move. They never do,
silence and the line drops ;-)

No,

A name is never transmitted to your phone.

Only a calling number or the withheld/unknown/etc code.

This is then converted to a name by your phone.

BT sends it in the name field of the callerid for international
calls, and also sets the unavailable flag. Other strings I've
seen turn up in there are PAYPHONE, WITHHELD (matches the
withheld flag), UNAVAILABLE (matches the unavailable flag,
except when international), OPERATOR.

The phone firmware - also for "unavailable" and "withheld" (which is
why different people see different words on different phones - it
depends what the manufacturer has put in so withheld may display as
"private". CLI is passed in the UK between the first a second ring
as a tone burst and comprises only numbers.

Does anyone know specifically why they don't do this, or don't at
least present the country of origin? I would like to ignore the
International ones as they are 99% marketing but I have relatives
abroad so I can't. BT surely knows the country of origin and probably
even the originating phone number in most instances these days.

If someone were to say that there is money in it for operators like BT
to ensure you do answer calls and they know all too well that if
presented with the country of origin perhaps 80% of those calls would
go unanswered from then on, I would not be at all surprised.

The message
from James Hawkins contains these words:

I would imagine that the originating country uses a different system to
ours and that the data isn't present or not in a form that BT can be
arsed to decode.

Not all "international" calls are really "international". I recently
had an "international" call from a company doing a survey, they claimed
to be in Lowestoft, I didn't ask them why they appeared to be calling
from overseas. On another occasion when I got one, it was from a mate
of mine in Cheshire. Knowing he gets about a bit, I asked him where he
was calling from, to which he replied "home". Turns out that he had
some cheap calls deal with Wanadoo, so they were probably being routed
via France.

The calls route through a number of countries and the routes change
by the minute depending upon bulk traffic costs. The originating
country isn't always easy to work out (as CLI information isn't
universal).

AIUI, it's pretty easy to forge the number that's typically sent in the
US, for example.

Yes, many calls using third party handlers such as 18866 or VOIP
originated calls will not show caller ID (and in some cases
misleading information like "overseas"!).

Some places which have a single incoming number, such as Doctors
surgeries, often withhold caller ID on outgoing calls from other
numbers. They could show something called a presentation number but
few do.

Some sales organisations show withheld or completely garbage numbers
(the latter invariably because of badly configured systems rather
than malign intent).

Do they only display names where the number and name has been programmed in
(like with a mobile?)

Yes.

or do they display all numbers?

Where number information is provided by the exchange.

Is it reliable?

What do you mean by reliable? For all practical purposes it cannot
be spoofed, so if 01442 123456 is displayed the call will be coming
from that number or that organisation (if it is a presentation
number). A normal caller cannot fool CLID (although VOIP originated
calls can appear to in some cases).

Will it display all numbers - no, as many calls don't include number
information.

Is what it says correct - no in that indirect calls and VOIP calls
may show as international when they are local (this isn't a fault -
the indirect carriers and VOIP suppliers find it cheaper to route
calls via overseas links at certain times of the day).

Be aware that if your phone service is provided by other than BT some
cable operators exchanges still use a different CLID system to the BT
one so make sure you get a phone which suits the system you have.

However, as it is free and as nearly all DECT phones incorporate it,
it is worth having. Don't forget you do have to ask for it to be
activated on the line.

They display all numbers of the person calling, unless that person has
deliberately withheld their number. I have had a lot of silent calls
to my office but not to my home which is ex-directory, they do indeed
display the number calling, this information is also logged, so that
information can be used later if these are malicious calls and are
admissable in litigation.
