Yes you could do this with sequential local calls.ExSp33db1rd wrote: ↑Fri May 15, 2020 9:46 amNot really a scam, but .... I once learned that one started a number with a - I think ? - a 3 digit "area" number that was dedicated to one's local exchange, so that if one started a number with one's own "area" number then it was only a local call, but anything else became a Toll call, don't press me, can't remember the detail now, but I stopped at every town and village from Heathrow to my then Dorset home, and noted the number to call the "next" place as a local call, then when I got home I rang them all in sequence, having by then something like a 24 digit number that would allow me to call Heathrow as a local call, instead of having to make what was then an expensive toll call ! Seemed to work until I ended up having to add the Heathrow number I needed, which started with a O, and that broke the chain. Foiled again. But it sounded like a good idea at the time !
The let down was lack of amplifiers, the signal got weaker the further you travelled.
