Oh, yes. When I read Chris' message I thought -- "good thing he's still
got some PSTN lines." I would never, ever suggest that anybody go all
VoIP. The reliability is a long way from being where it needs to be. As
an adjunct, it's great, but I'd never replace PSTN service across the board.

Obviously I can't speak for BT and the UK circumstance, but once the
card a TDM400P card is tuned properly (which, I admit, can take some
effort), the call quality is excellent. The biggest hurdle, of course,
is echo, and SIP calls aren't (normally) afflicted with that because the
echo cancellation is present along the entire path.
