I have a one-line Panasonic machine which I think has the same logic as your two-liner. It's model number is 1470. There is a switch, referred to in the instructions, which has to do with automatic detection of a hang-up by the caller. This hang-up produces a momentary voltage drop on the phone line, and unfortunately call waiting does the same thing. The answering machine detects this drop and disconnects. The purpose was to avoid getting about seven seconds worth of blank tape when your caller hangs up; you see, the answering machine will also disconnect after enough seconds of silence. The instruction book said that if you had call waiting, you should flip that switch on the answering machine and disable this rapid disconnect feature. You would then have to put up with these tape trailers after your caller stops talking and hangs up. Personally, I wouldn't have call waiting if they offered it to me for free.

Illinois Bell had a recent promotion in which they *did* it away free to new users who bought other custom calling features. PT]
