I have just checked my landline bill, which I must admit I don't do very often and was a bit alarmed at mobile costs for a 2 or 3 second call - 15p each time - this is me just ringing (2 or 3 rings) my mobile to find it!!
So it costs me 15p to find my mob, phoned Talktalk and apparently every time you dial a number and it rings you are charged - when did this happen!! I always thought you only got charged if you got an answer?? News to me!!
