More to the point: don't give out such details to people who call you. Or email you, chat you, or use Apple's new iMind telepathic enabler.

Assume everyone asking for such things are scammers.

>Assume everyone asking for such things are scammers.

That's excellent advice, and everyone should follow it. Unfortunately some banks disagree and will cancel your credit cards when you fail one of their fraud check phone calls.

> And guess what, the only way to be sure that it’s your bank you’re talking to, is to call them yourself. Period. Some callers tell you details of your account as a way of identifying themselves.

There's a scam in the UK where they call you, and ask you to call them back. You hang up, then pick up the phone and dial the number. But because they initiated the first call the line doesn't clear until they hang-up, and they don't hang up while you're dialling the number. (And the sometimes play recorded ring tones before they "answer").

That seems like an odd way to run a phone system. Couldn't I keep someone from making any outgoing calls just by calling them once, and leaving my phone off the hook?

It varies a lot, or at least it used to. Keeping the phone line open and expecting a callback is a scam so classic it's even in the first edition of "Practical Unix (now "and Internet") Security" in the section on securing your modem pool.

It's very frustrating hearing someone walking around when they think they've disconnected but they haven't.

That sounds more like a hoax of a scam. I doubt the phone system works that way.

Here's a page from Oftel (the official UK regulator of telecoms).

(http://www.ofcom.org.uk/static/archive/oftel/consumer/advice...)

> When do you stop paying for a phone call?

> Call charging ends when the telecoms company disconnects the call. This is usually but not always when the caller hangs up and the call appears to end.

> Voice calls The caller originating the call must hang up for the call to end. The person receiving the call may hang up, but this will not end the call unless the originating caller also hangs up. Only when the originating caller hangs up then will call charging end. You should always check you've replaced the receiver correctly. If you have any concerns that your call has not ended, you should check that you have a dial tone - this indicates the previous call has ended.

Here's a story from the shitty Register about this method of scamming people:

Wow, thanks for the clarification. That's incredibly stupid, I can't see the upside in that, aside from the telecom being able to charge more minutes per call (which is likely why it still functions that way.)

It allows you to hang up the receiver in one room, walk to another extension and pick it up without disconnecting the call.

-----

illuminate 511 days ago | link

Sure, we just walk to the other extension and pick it up first. The minor amount of time saved sounds like a poor trade-off considering the potential for harassment.

-----

bonaldi 511 days ago | link

The potential for harassment is greatly ameliorated by the fact it's the caller who pays -- receivers don't pay anything in the UK, ever. And while you're harassing, you can't use your phone.

I don't think I've ever heard of anyone being harassed in this way. A few pranks, maybe.

I'm certain it has a lot more to do with the state of technology in the 1950s than with malice or incompetence.

The behavior certainly isn't replicated on mobile phones.

I remember setting up three-way calls like this when I was a kid (and had a landline... not sure it would work with a cell phone).

That's the problem with inventing everything - you end up with 'v1' of everything. And v1 is always awful. :p
