I've never heard of it working like that back when they had to manually connect each call maybe but not today.
Its worked like that for years in the UK
In fact not that long ago there was a scam where the scammers would call house lines and claim to be debt recovery department of BT, they were telling the customer that they owed £X amount to BT and if they didn't pay via card over the phone to them right there and then, that they would cut them off
They continued by saying if you need proof, hang up, wait 5 seconds, then try to make a call, you will be disconnected
So some people were hanging up, then lifting the receiver and hearing no dial tone, hanging up again and waiting for the scammers to call back
All they were doing was hitting 'Mute' when they heard the customer hang up, the customer obviously can't make a call as they are still connected to the scammer, and they can't hear the scammers end of the call because they have it muted
So some people waited for the call back and gave their card details to some guys in a flat scamming thousands of people out of their money
Try it, call someone, tell them to hang up and then pick back up, you`ll still be connected (Only works on landlines)
I used it about 15 years ago to seek revenge on a cheating girlfriend, she had given me her charge card number so I could call her house free, when I found out she cheated I walked to a pay phone in the middle of nowhere, called her with that card number then left the phone on top of the box
