Query: Hiss? You'll find a pattern.

I have a problem with constant hiss as well, but on my HS-8270. I'm in the market for a new 2.4 GHz phone with speaker, CID/CWID, and an answering machine. I was down to this one and the Vtech 2461. I've given up on finding a good one with a base keypad (forget the Panasonic or the Uniden!).Looks like this background hiss may be pervasive in AT&T's line. Looks like I'm going Vtech.
