As I recall it I simply (in ignorance) connected into the spider
ridden
old BT box with the incoming pair and it worked with a normal modern
phone. The old BT phone had been fitted with a new lead and a
modern jack
plug, and this worked on another extension that I had nothing to do
with,
but when this was used in the extension I wired up did not ring.
There you have it in all its horrible detail if I've remembered
correctly!
In that case, the easiest thing to do is fit an ADSL filter as
suggested
earlier
Many thanks Graham...will try that
Cheers

Thinking about it you may still have a problem, depending upon line
length.
Older (70's) type phones would have a bell load that corresponds to a
modern REN of 4 or more - the BT stated maximum you can have on a line.
If the line from the exchange is long (and especially if it is old)
there may be too much line resistance for the other phones to ring when
the 70's phone is plugged in. My experience is that most lines will take
an equivalent REN of at least 6 before they start to play up, but be
warned.
