Thats known as a loop. Lots of them out there but most are muted so you
can't talk on them. Other prefix exchanges worked too.
The other fun thing is to find a bridge which is a bunch of numbers toed
together so several people could be on at once.
I used to be a phone phreak in my younger days back when the blue box (for
free long distance called) used to work.
The coin sounds in a payphone is called a red box. Doesn't work on COCOT
(customer owned) payphones because the dialtone you hear is not from Ma
Bell's line but generated by the phone.
