Lightning strike protection

[James Fidell <james@xxxxxxxxxxxx>]

Guess who has broken stuff to replace this morning? :)

We had a cheap phone die in the storms on Friday morning and somehow,
though I can't see how, the switch port that my adsl router is plugged
into stopped working with a loud "pop" last night.

So, before I move to asterisk and risk blowing up an entire PC, I could
really do with some sort of protection from lightning strikes on the
phone lines (they run over ground, over the tops of hills, for about
three miles to the exchange, so an easy target for lightning).

Any recommendations?  Preferably avoiding moving house...
