    I have my HTC desire a couple of weeks now and I have some weird problem.
    At random times I get a call by an 'Unknown' number. When I answer the call there's no one there and the other side hangs up.
    The problem started when I got my new phone so I don't think it's my provider. Also it can't be a prank caller. If it was I should've at least heard something on the other end of the line.

    Does anyone know what causes this problem? A bug perhaps?

    Thanks in advance,

    I'm going to move this over to the Desire forum for you. Maybe one of the members there will have an answer for you.

    I get unknown calls all the time from random people asking me if I want loans amongst other things.Wouldn't worry about it.

    Edit: Although if there's no one on the other end it's probably just a prank.

    But there's not even a sound on the other end of the line, no noise or something. Also I can't think of anyone I know who would do such a thing.

    I have heard of people making phone calls because their pocket is dialing, but this is weird. Try calling your phone provider to see if they can confirm your being called. If you manage to answer and it doesn't say missed, the carrier should have record of the call being completed i would think.

    I can't think of anything to do with the phone that would cause that. Does it log the number? If so I'd find a way to get it blocked. If not, as suggested above, ring up the network provider and see if they can tell you who's calling, and if they can give you a number, block it.

    it doesn't show a number just 'Unknown'. Also it doesn't show up in the call history.

    I have the same problem.

    I get called 2 times per hour (but not accurate on the minute), and the other side Seems to hang up. After the first time I immedietly got suspicious and never picked it up again. It answers my voicemail, and in there I have a few dozen recordings of the the-other-guy-just-hung-up tone -> weird.

    When the other person hangs up, the tone isn't recorded (or mostly for 2 seconds, not 10).

    So I'm thinking the other side Never hung up, I suspect it's a scam of some sort and possibly related to one of your/our/my Android apps.




    I think we should both follow Phenomenological's advice and call our ISP. Keep a record of the times you where called so there can be no mistake. ​

    We see this type of behaviour a lot on phone systems.
    Usually it's an automated dialler that calls numbers in bulk validating that they exist.

    I've started getting more 'sales' calls to my mobile, so it could be related to that.

    You can register your mobile with the Telephone Preference Service (TPS)

    TPS Registration

    As an a side... for you PSTN Land Line.
    BT offer inbound Caller ID which they charge at a fee per quarter.
    or for FREE you can get BT Privacy at Home.

    Which give Caller ID & TPS registration, for free as long as you make 2 chargeable calls in one month.

    After 2 weeks of them calling with no one on the line when I answered, I finally got someone. She said that she was with TSYS and wanted "Doris". They are a particularly "scummy" bank / merchant services / collections company. Here is their contact info:

    TSYS Corporate Communications
    P.O. Box 2567
    Columbus, GA
    31902-2567
    +1. 706.649.4266 fax
    +1.706.644.3110 phone
    +1.706.442.2321 mobile

    If you keep getting calls from "Unknown Number", give them a call and tell them to stop.

    Best,
    Joe B.
