Nationwide....

Good advice .. but not necessary if you're calling using a mobile phone - once you hang up the call is disconnected; it's only with a landline where that technique can be used. And I'm not sure if that still even works with the new digital network (i.e. calls via your Internet connection rather than the physical landline).

I wasn't sure if every mobile phone disconnects or if the new digital network behaves the same but I think you are right. Another advantage of ringing a friend first is that it gives you a bit of thinking time and someone to talk about the dubious phone call with.
