More bullshit, I guess you never "pinned" a phone call.
All you had to do before the current crop of electronic pay phones was
short the tip to ground to open the originating register on a pay
phone line. It was done be sticking a pin in the cord and shorting it
to the frame of the phone. That was why they started using armored
cords. Then people stuck the pin in the mike or earpiece holes. Ma
Bell started using an armored element there too.
The caps are typically glued on.

I had a regular phone connected to a pay phone line at a pool I worked
at. (the fools had the Dmark in the lifeguard office) We shorted the
line with our whistle and got out fine.

Technically, yes, if you got caught. There might be
operational problems too since the UK uses different
ringing frequencies and patterns than we do here. Ring
detection is always the biggest problem manufacturer's
have in their designs. The phone may or may not ring
if it had an electronic ringer, espeically if it were
not designed to allow for multi-country patterns, etc..
It's kind of a long subject, but technically,
depending on where you were in the UK, it -might- work.
Since it's a pay phone, if any of the coin sensors
are still working inside it it's going to have a hefty
REN (Ringer Equivalence Number) also. It's possible
but not necessarily likely it might set off an alarm in
the central office as the phone tries to switch to the
coin ckts. They would definitely have to be disabled.
The brits are more strict with their phone
regulations than we are here in North America. They're
stricter with lots of things. Like over $1,000 to get
a driver's license, a tax called a license, to own a TV
set, which you must be able to produce upon demand,
etc.. The TV thing came about in the war when they
were being turned into transmitters with their parts
and the laws were just never changed - so now it's
actually a tax but the law is still there about the
license, so ... ya get one when you buy a TV.
Lotsa interesting stuff 'cross the pond as they call
it. \

HTH,

Pop

PS Henslee's got a neat set of responses, eh? Guess he
figued to cover both bases; no way he can be wrong with
two conflicting responses.
