When someone calls your mobile and the caller ID says “unknown number,” does it mean that your mobile does not recognize that number?
Without a Caller ID Service Enabled:If you are not using a carrier provided Caller ID service (Verizon, or T-Mobile, etc.) and do not have any third-party apps running (mainly applicable to Android, for example TrueCaller) then it likely means one of two things:The caller has decided to use the *67 feature and your carrier’s switch interprets the privacy flag as ‘UNKNOWN’, rather than what you may expect to appear if someone blocked their number when dialing (‘PRIVATE CALLER’ or ‘BLOCKED’, I assume).The caller’s carrier has set the private flag to true in the SCP (CNAM storage level), thus accomplishing the same thing as *67.Less likely, but still possible: There could be instances where your carrier’s switch did not receive the CID (phone number) and thus displayed ‘UNKNOWN’ rather than the number.With a Caller ID Service Enabled:If you are using a carrier based Caller ID service (again, think VZ or T-Mobile) or this is a result provided by a Caller ID app (again, think TrueCaller, etc.), it likely means there is no value being stored for that number or that the app doesn’t have a value for that number. With that said, the same reasons I listed for occurrences without any Caller ID service enabled could also still be a possible reason, though.
Why are random people getting calls from my number even though I never make those calls and neither do they show in my call log? And how I do stop this?
This may be someone spoofing you, which is changing the caller ID their phone sends so that it's your number. The phone companies allow this; the legitimate use case is for a firm that owns a PBX (basically its own phone system) to set the caller ID to anything it wants, so e.g. returned calls all go to the same number.If the intent of the spoofing is to defraud whoever answers by pretending to be you, it's a crime. You can report it the FCC, see Spoofing and Caller ID .There is, or used to be, an odd attitude in the phone company (I know firsthand about AT&T) that the payer for a phone call gets to control the identifying information. So for caller ID, the person making the call pays, so they get to control the caller ID. ANI is a similar system that identifies the callers of 800 numbers (toll free numbers) to the companies they call. The callers cannot change their ANI information, the stated reason being it's the receiver who pays for the call.
I sometimes answer calls from unknown numbers but once I say "hello" they end the call. Am I being hacked?
Large telemarketing firms use computers that dial hundreds of numbers at a time. Most people don’t answer. However, on any call where they detect a human voice saying hello, they patch the call through to a waiting agent. If no agent is available in 5 to 10 seconds, they disconnect the call and put it on a list to try later. The game here is to employ as few agents as possible and keep them 100% utilized. If that means that people are disturbed by hangup calls, they don’t give a shit. They still make their money.This is why if you say “hello,” you will sometimes hear a delay of a few seconds before you hear the noise of the telemarketer “boiler room” and a startled agent (who did not call you or hear you say hello) launch into their script.If you want to amuse yourself, pick up the phone and DON’T say hello, and note how long the silence persists before the robodialer gives up.Or, better, say “hello” and then when the startled agent picks up after a few second pause, act like you called them. “How are you doing! I’m so glad you picked up! I’ve been calling for days and I can’t believe I finally got through!” Since they didn’t place the call, they will be very confused since it is POSSIBLE that someone called them, since that’s how they receive calls. Continue the insistent act like you called and they will assume there is a glitch in the system and chase you off the phone.
My caller ID says that the phone number is "Unassigned." What does this mean?
Is it happening to all the phone numbers or with any particular number , do you have the call display feature to display the numbers of the incoming and dialing calls? it could be a problem with your call display too. did you try fixing another phone on the same line to see if you still habe the problem , if you have then...... call your service provider and place in a report
What does it mean when a "private number" keeps calling me?
"Private Number" can be inserted into a caller ID field in place of the actual phone number. Since Caller ID is not required to enable calls these days, that field can be spoofed with anything. If you dont want calls from anonymous callers, you can set that with your provider to reject those calls and force the caller to enable or enter their caller ID.Most likely its a telemarketing call which is trying to reach random people, and if you answer it and hear some robodialer auto sales message, you might be able to sue them for $500 per call after you opt-out and then keep calling you. Its annoying but it wont stop unless you remove yourself from their dialers.
How can I get a fax machine to stop calling my home number?
Best approach: Call your local phone provider and ask if they provide "call block" service. Most phone providers do carry "call block" service. I have had this exact same problem and the best thing to do is to use this service. All you have to do is activate your call block service and it will automatically ask you if you want to block the most recent number that called you (you might not have Caller ID or be able to *69 to get the number). This way you don't have to even know the number, you can just activate the call block immediately upon receiving one of these annoying calls. Of course, if you DO have caller ID you can just access your "call block" feature and type in the number you want to block. Works like a charm!! The only downside to this service is usually you can only block a total of 6 numbers at a time, but that's usually not a problem. After blocking a number for awhile, the person will stop calling anyway and you can take their number off of the blocked numbers list and add another number to be blocked if you should desire. Hope this helps!! It's the best way to stop those annoying fax calls, trust me!
My friend keeps giving my phone number to some people I barely know?
Hey, you should be straight with your friend and tell him that you do not want ur number given out to random people you hardly know. I know it sounds mean but you have to tell him cause you dont wanna get anymore random numbers txting you. Also another thing what u can do to stop getting text messages from random people are, get your phone company to block there number that way they wont be able to bother you and they still waste there credit. Hope this helps :)
How can I find out who called me from an unknown "No Caller ID" private number?
Zahid Ullah Khan , Becca Owen, thanks for your A2A.You may try, by reporting it to your local authorities, in case you have suffered any sort of crime, by means of this unknown call (for example being stalked).This will probably trigger an investigation that will require your telecom operator to do some research.If your telecom operator finds the source of the call, you are lucky. If not, because the call was originated from another telecom operator, the investigation will go on and repeat the steps above with the new operator.Unfortunately this procedure may fail if the next telecom operator is located in a country where your court order has no power or where there is no data retention law forcing telco operators to store their logs for however long.If that happens you may not be able to ever find the source of the call, not even with a court order.You may decide to block all incoming calls without caller-id (it may or may not work because, if someone is stalking you, it is also possible to fake the caller-id), or you may decide to use secure phones, such us ours, where only people who you have explicitly authorized, can call you. Others simply cannot.
