Usually, when you call somebody's cell phone and hear a beep after each ring, it means they are on the phone with somebody else. Are there any other ring indicators like that? [more inside]

I'm sure there used to be a code one could dial on UK telephones which would cause the line to ring - thereby achieving intercom functionality? This number was something like *173, but either my memory fails me or it no longer works. Any ideas on the specifics?
