Could you tell us more about how you set up your 840av as an answerphone, and how you make it work on the network? I had thought that the audio recorded by Apple Telecom software would be incompatible with OSX....

One of the retrochallenge projects from a year or two ago involved Apple Telecom and Applescript doing something similar, as I recall, but the details have seemingly disappeared from the web. (Speaking for myself, I'd dearly love a copy of those scripts, should the scripter ever read this post!)
