I stand by my analogy, whether or not your or Fargus understand it. Good luck, I doubt your interpretation has much relevance in a court of law, in the admittedly unlikely circumstance that it comes to that. You should just read the Wikipedia article on this. It talks about the UK as well, my comments were more specific to U.S. (You didn't indicate before that you were talking about the UK.) It does appear in the UK you can record a call without notification purely for your own purposes, although you can't share this recording with any third party. If you're placing an international call though, the applicable laws may be very different.
