RE: Reversing phone line polarity, was Re: windows caller id and answermachine solution

["Keith Doxey" <ukha.diyha@xxxxxxx>]

Cant see why it would work unless the CallerID unit was polarity sensitive
which is bad design as telephone lines often get reversed when cables are
worked on.

If you do try reversing the line, you need to do it at the main incoming
point.

REVERSING THE LINE BETWEEN SOCKETS WILL CAUSE BELLS TO RING PERMANENTLY.

Sorry, had to shout incase the bells were making too much noise :-)
