Of course, these days if you ring an invalid number from BT (I don't know about other providers) the NU tone has been replaced by a woman who repeats over and over again (for about a minute) "The number you have called has not been recognised." Also the engaged/busy tone now has a message superimposed upon the tone saying that the number is busy and encouraging you to use the ring back service (for which there is normally a charge), though this message isn't repeated, continuing with just the tone until it times out.
