P.s. that reminds me, you need to keep an eye on the REN load on the phone
line.

BT phone lines can support a REN of 4.

Simply add up all the individual REN numbers of your telephony devices. If
t comes to 4 or more, you will need to fit a REN amplifier between the BT
master socket and your telephony patch panel.

REN stands for ringer equivalent number.

Not convinced that that matters anymore with modern electronic phones.

And it makes a lot more sense to use cordless phones
now than fart around with lots of non cordless phones.
