Phone sockets to patch panel
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.
