On: When in doubt: hang up, look up, and call back

> A favourite trick in the UK is for scammers to stay on the line when you hang up, and play simulated noises for a dial tone and connection, then pretend to be your bank when you call the number on your card.

Sure, but that only works for landlines. Is this still a common thing in the UK?

I haven't had one for 5 years but I think am in the minority. Many households need one for broadband as they can't get cable.

Most broadband "landlines" are not a real BT landline but instead one simulated by your broadband router (it's SIP on the other end). With SIP, once either you hang up or the other side hangs up the session is terminated and there is no way to recover it.

As far as I'm aware BT still have normal landlines to most areas - the phones are separate from the router, they don't go through it first and even support old pulse dial phones.

I would be extremely surprised if most UK “landlines” are actually SIP extensions. Do you have a source for this claim?
