Cellular Phone Forum / Providers / ATT Wireless / February 2008Will we see Inbound caller ID name?
Is there a reason almost none (well, ok none that I'm aware of) of the cellular carriers show a name with the inbound caller ID? On my home phone, I see the name of the person calling on my caller ID. A cell phone just shows the number. Is there a reason? Any cell phone carriers looking into adding this?

They don't make any money or use up that airtime so they can sell you more if you DON'T click SEND to find out who's number that is. It's to no advantage to any carrier for you to have data that's sent right to his terminal. >The carriers don't want you to know who is calling you.

You're right. That's gotta be it. It's then certainly a mistake they give you the number on caller ID too. SignatureTo reply via e-mail, remove The Obvious from my e-mail address. > It's then certainly a mistake they give you the number on caller ID > too. > - Nope. If you see a number you don't recognize, you'll have a tendency to find out who it is. Good psychology on their part. The number also lets the phone recognize the people on your contact list so the phone can display your contacts calling with the appropriate special ringtones if you have it set up right. NOT sending you the number would render these features inoperative. >Nope. If you see a number you don't recognize, you'll have a tendency to >find out who it is. Good psychology on their part.

A cell phone just shows the number. The name shows on my cell phone. If I have the name in my address book on my cell phone. Names are shown on landline phones caller ID without being programmed in?

Obviously, the name will show on your cell phone if it's in your phonebook. But yes, the billing name shows on a landline caller ID.

But yes, the billing name shows on a landline caller ID. Interesting that the billing name shows up. I did not know that. Is that really that useful unless the call is from a cell? What I mean is that calls from landline phones are often used by more than one person. So you would more often only have the billing name which might be anyone in a household or company while a cell phone is usually personal.

Okay. I guess I have gotten used to only taking personal calls on my cell phone and giving out that number. The landline does not get many incoming calls.

On a landline with caller ID, you can dial *77 (at least in my territory (California, PacBell/SBC/ATT/WhateverThey'reCallingThemselvesThisWeek)) and it will set a flag of some kind where calls that do not reveal their caller ID information are prevented from ringing your phone before it reaches you. Before the call reaches you, the call is diverted to a recording that tells you that this person does not accept anonymous calls, please dial *whatver to unblock your number this time only, or use a payphone first. They call it anonymous call rejection. It's great. But I pay monthly for caller ID on my landline also. >> Yep. Obviously, the name will show on your cell phone if it's in your >> phonebook.

Yes, it's useful -- Especially when the call comes from a company that you do (or don't) have business with. It's nearly as useful with cell phones (I am lucky enough to be on a carrier that offers name display, both inbound and outbound for mobiles) > Names are shown on landline phones caller ID without > being programmed in? Yes. The local phone company has access to directory information, so (for a price) they'll add the name. > Yes.

What shows on the landline caller ID if your number is unlisted or unpublished? Or if the call is from a cell phone? SignatureCharles > > Yes.

No doubt. > What shows on the landline caller ID if your number is unlisted or > unpublished? Or if the call is from a cell phone? Let's see, unlisted/unpublished still shows the number--not sure about the name. Blocked call shows a variety of things, none of which are any identifying information. Anonymous, blocked, whatever the cell carrier wishes to show when the "blocked" flag is set for the sending call. (Do note that the number itself is carried along with the call; those who block merely have a "block" bit going along with it, and the entire system counts on receiving equipment to honor that blocking bit. As you can see, a blocked outgoing caller ID doesn't mean diddly to people who want to know and are in the position to have such receiving equipment.) Cell phone might show "cell phone" or anything else as the name. > Let's see, unlisted/unpublished still shows the number--not sure about > the name. Qwest, my landline carrier, sends the number with "Unknown Name" as a name. > Blocked call shows a variety of things, none of which are any > identifying information. Anonymous, blocked, whatever the cell carrier [quoted text clipped - 4 lines] > can see, a blocked outgoing caller ID doesn't mean diddly to people who > want to know and are in the position to have such receiving equipment.) You're giving way too much credit to the receiving equipment. Caller ID is just a string of text sent by the phone company, and the CID display boxes are dumb displays. The phone company sends what your display sees. A blocked number just isn't sent- there's nothing for your box to "honor," and my guess is the choice of text comes from the originating phone company- I've seen "Private," "Anonymous Caller," etc. Having said that, calling 800#s gives out your information on the premise that someone paying for the call has the right to know who's calling them even if you block caller ID. That's not CID, however, but a different (older) service called ANI. > Cell phone might show "cell phone" or anything else as the name. Depends on your carrier, perhaps- if I call you from my T-Mo phone, you'll see my name. Sometimes I see the caller's name, "Wireless Caller" or even the carrier name. >You're giving way too much credit to the receiving equipment.

A >blocked number just isn't sent- there's nothing for your box to "honor," >and my guess is the choice of text comes from the originating phone company- > I've seen "Private," "Anonymous Caller," etc. That really depends on the type of service you subscribe to. On an analog loop, you're correct. However, for digital services (VoIP, ISDN, T1 and up, etc) all bets are off. The telco easily can supply the phone number and other information, along with a "Private number" tag. > Blocked call shows a variety of things, none of which are any > identifying information. Anonymous, blocked, whatever the cell carrier [quoted text clipped - 4 lines] > can see, a blocked outgoing caller ID doesn't mean diddly to people who > want to know and are in the position to have such receiving equipment.) Myth. I questioned that so I Googled for more info on the format of the CID data stream (sent between the 1st and 2nd ring). There is NO "block flag" or anything like it. When a call is blocked the standard calls for replacing the entire NPANXXNNNN phone number with the single letter capital-P; i.e. the calling number is NOT sent. If it was there'd be a whole market of non-blockable callerid boxes. This idea probably grew out of someone's confusing caller id with the ANI (Automatic Number Identification) service available (for a fee) to 800 number customers. That's sent on a seperate circuit and cannot be blocked. Not all 800 customers pay for real time ANI since they get the calling number shown on their bill without it. SignatureJud Dallas TX USA > That's sent on a seperate circuit and cannot be > blocked. Not all 800 customers pay for real time ANI since they get the > calling number shown on their bill without it. One of the biggest benefits of calling 800 numbers with Skype Out is their total inability to extract your telephone number from ANI. Skype always sends 0001234567 as the caller ID number when you make a Skype Out phone call on POTS.....a real feature, I think. This, I'm sure, is one of the reasons I've never gotten a spammer calling my Skype In phone number. The other reason is my phone number, here in Charleston in the states, is in the same number block as AOL uses for dialup modems, and is probably locked out of all autodialers at the boiler rooms across the planet. I'm not sure about my London Skype In number. The only unsolicited calls I get on it are wrong numbers looking for hubby at a pub. My number is one number off theirs and is easily dialed, it seems, in the heat of anger when he doesn't show up at home when he's suppoed to. Those calls are hilarious and I wouldn't change them for anything!.....(c; I've taken to answering my Skype In calls with the pub's name....(c; NOBODY gets my Skype phone number when I call them....not even the Mossad. > One of the biggest benefits of calling 800 numbers with Skype Out is their > total inability to extract your telephone number from ANI. Of course, the foil hat you're wearing doesn't hurt. Right, Larry? >> That's sent on a seperate circuit and cannot be >> blocked.

The ANI number isn't that fake number, however, it is a real number which belongs to the company which terminates Skype's PSTN calls, Level 3. I know this because when I once used Skype to call my bank's 800 number from overseas, instead of the menu system I expected the call was instead routed directly to the bank's security department. Apparently the ANI number was on their suspicious list, so they wanted to talk to me about that. Skype caller ID works works fine with SkypeIn numbers if you tell it to do that, by the way, with the only catch being that it won't let you use a US number for the caller ID. Your UK number would show up fine on calls to US cell phones if you wanted that, though overseas caller ID numbers aren't usually delivered to landlines.

It is true that a blocked number is not delivered to a subscriber's line. I think it is the case, however, that the calling number (along with all the numbers from which the call was forwarded) is carried in the SS7 signaling all the way to the telephone switch serving the called party, and it is this last switch which is responsible for deciding whether to deliver the number to the subscriber or not. So, while a normal subscriber isn't going to see blocked caller IDs, they are probably available to someone with more intimate access to the phone switch. Dennis Ferguson |
