My DSL has got a bit slower recently and keeps disconnecting.

There is some kind of fault on the line. It seems to be connected to someone else's telephone line in some way. When I pick the telephone up, my dial tone starts, and I can hear some old lady's call. They can obviously hear my dial tone as they keep moaning about it when I pick the phone up.

When I dial 1471 I get both my last call and their last call simultaneously.

Judging by listening to their calls, they thought this 'dial tone' issue was down to a fault with their telephone set . I suppose I shouldn't be listening in, but I'm too nosy .

The line was really noisy a week or so ago, so I wonder if they may have connected something up wrong at the exchange.
