Entry phone door release - PAL WinTec

[PeterD <stillcentre@xxxxxxxxxxxxxx>]

Pal WinTec offer a neat entry phone system.  It introduces a ring
tone, from a visitor pressing a button on the door panel, to all
ordinary phones in the house including cordless ones.  You can then
answer it and talk to the visitor, and activate the door lock release
if you want to let them in.  It can work with more than one door eg
front door and back door, using their PAL 102 system.

At least, that's what they claim.  But their documentation is poor
(the only detail is in Hebrew, not English!) and the system expects
telephone wires to be only a single pair, ie 2 wires, and does not
provide a standard plug to take the incoming phone or to output to the
cordless box.  Here in England, all the phone lines end with 4 wires,
and don't seem to work with the WinTec 2-wire assumption
- any advice on how to connect them would be very welcome!
