There's ringing signal on PIN 3 even in the master socket in a normal BT POTS setup that's what the capacitor is for wink

But this is a thread about a Hyperoptic installation, nothing to do with a normal 'BT POTS' set up ????

CPE should be sending something otherwise the phone wouldn't ring.

Maybe it can't supply enough current.

Edit:

The other one I've sometimes seen is a non standard Pin-out at the phone end requiring you to pretty much use the cable that comes with the phone

As I said before, perhaps there's no ring signal on pin 3, or as you say maybe there is but not enough current.
