    I realize this is somewhat removed from the topic of the newsgroup, but
    I searched for another group and found none specific to my question
    type. Since this group is filled with knowledgeable people in
    electronics, I thought I might find an answer.

    I have several cordless phones in my home hooked to my single phone
    line. They are both different models by the same manufacturer (AT&T and
    GE), and of course different brands. My question is why does the data
    listed for Caller ID differ from phone to phone? One will list the name
    of the person while another might only list the town along with the
    phone number. I thought the data was supplied by the originating phone
    company and therefore would be the same for each phone.

    Just curious. Thanks.

    I don't have caller ID, but always assumed that the phone would only
    display a name if you have that person's name programmed into the
    phone's speed dial system. Isn't that the same as a cell phone?

    No, but I believe that some of the info is generated from within the
    phone. Mostly, it's related to lack of info, like unlisted and blocked
    ID's, that varies from phone to phone.

    Cells vary as well, as to the degree that they display ID info, I believe.

  4. That's correct -- it is and it should be.

    Presumably different manufacturers select different CID items to display.
    Check the user manuals -- it might be possible to change what's displayed.

    This appears to be the case, but I see no mention in the user manuals
    as to how to select what is displayed. It is a little bizarre that
    phones made by the same manufacturer display different data when a call
    comes in. Of course they are probably "Contract made" rather than made
    by the name of the company on the phone.

    Smitty Two seems to be somewhat correct in that at least one of the
    phones puts the name for caller ID as it resides in the directory (i.e.
    Johnny) in the phone. Others appear to use the listing as it appears in
    their phone company customer records (i.e. John Smith).

    Because you can't... The dsigner made that decision for you.
    Which means nothing. Possibly designed by different branches of the
    same company. Though I am confused since you said one was a GE and the
    other was an ATT...
    Good guess, that is what i'd think too.
    Caller ID information varies by provider, country and other factors...

    Just to clarify this point. I have two AT&T phones and two GE cordless
    phones, each different models.

    I always keep my Bell south (at&t) land line phone Unplugged, except for
    when I want to use it.
    Nobody here but little doggy and
    I.We have some stormy weather going on here right now.That LOUD clap of
    thunder scared the pants off of her.

    Caller ID in the UK appears to supply only the caller's number and world
    location if appropriate ie nothing on that score if the call comes from
    within the UK or "International" if not. If the caller has their number
    restricted with the phone company, it comes up "witheld". The only phone
    that puts up a name, is the big multifunctional one in the workshop, and
    that one only if the caller's name details are programmed into the dial
    memory, so that it recognises them. It's high time that legislation was
    changed to force cold sales calls to be identified in caller ID, as some of
    the companies are getting pretty clever at 'disguising' the number that they
    are calling from, so you pick the phone up to take what you think is a
    customer call, only to get " Hello sir, my name's Mandy-Lou, and I'm calling
    to let you know that your address has been picked to receive a free .... "
    at which point the phone goes gently (!) back down.

  11. The word withheld seems to come from the phone. One phone I have
    displays it, the other does not.

    Pennsylvania allows customers to select "anonymous call reject"
    if you pay the extra money for caller ID. I don't know if any
    other place has it, but I sure miss it.

    Y'all might think about outlawing telemarketing altogether, as we did a
    number of years back. Quite a relief.

    Well, yes. I'm pretty sure that is the case, and that the phone does it as a
    result of reading some flag bit in the data stream that's been set by the
    phone company to tell the phone that it's not going to be supplied with
    number data.

    You can opt for this feature also in the UK. The trouble is, many of the
    shops that I deal with withhold their number legitimately, because they
    don't want customers to get hold of that particular number, so by opting to
    reject all 'withhelds', you can also end up rejecting calls that you really
    do need to take. Some institutions like the police, for instance, also
    withhold their number, for obvious reasons. I don't know about where you
    are, but here in the UK, cold sales calling has now become such a nuisance,
    that sometimes, you can receive 10 or more calls in a day, often carrying on
    until 9 or 10 at night. This is presumably after some company that you have
    had legitimate dealings with, has sold off your details to an Indian call
    centre company. That's why I think that it's high time that people's privacy
    was restored, by making cold callers electronically identify themselves, so
    that a rejection filter can be set up for them alone, or at least, your
    caller ID can identify them, giving you the choice of whether or not you
    wish to pick up on the call.

    Where? That would be great.

    We have the do not call list here, but it doesn't apply to political calls
    or charities so while it's not quite useless, it leaves much to be desired.

    There is a married Irish woman in Bognor Regis,England, married to that
    Irish guy.She has phoned me quite a few times before.I don't know if she
    has caller ID though.I am not going to ask her about that.She works at
    her home (via an IBM laptop computer WSCC gave her to use) for West
    Sussex County Council.

    Was talking about the U.S. of A. The charities are a pittance compared
    to what the telemarketing used to be, and any of them will take you off
    their list if you ask.
