[Martin writes how phone notification systems should work.](http://www.telepocalypse.net/archives/000835.html) About how taxi companies notify him by a "callback", and how he wants to pick what phones ring when. Good stuff. We can only say that Skype is not done yet and these are definitely the kinds of "new frontiers" we are going to explore.

> Wanted to call my wife when I got to my parents’ house. Checked first to see if she’s on Skype. No deal, so I call. She’s out. The problem is, I’m afraid to call in case I wake up sleeping babies. We only have one landline phone sat in the study where the littlest madam sleeps in the day. But even if I had a second one plugged in and, say, in the kitchen, I can’t selectively ring just that one. So no point. Yes I could hack up all sorts of schemes to get around it, but there’s no out-of-the-box solution whereby the caller can select the nature of the ring/interruption (“sotto sotto”, please).
