Not at my school but I heard this at school
The school I went to was pretty boring with regards to school stories. This fact was constantly bleated out by one of the girls I went to school with.

Anyway, she used to go to a boarding-school in Ireland. Often, she and her friends would try and sneak out and buy cigarettes at the local shops. The shops and the school had an arrangement where if the shopkeeper spotted someone attempting to buy/steal cigarettes, they'd notify the school by telephone.

So anyway, the pupils had found a way round this - they managed to climb up a telephone pole and somehow tamper with the telecommunications wires and insert a phone of their own. By some miracle, they were able to intercept phonecalls to the school and when the shop called, they'd do their best secretary-impersonation and get away scot free.

Nowadays, one of my friends is a telecomms engineer, and I've never asked him how feasible it is for a bunch of naughty schoolgirls to have enough knowledge of telecommunications to intercept a phonecall. Bear in mind that this was the mid 80's.
