That sounds like a bad install. It's always unfortunate that a line which clearly has issues according to the DSLChecker is further impacted by a poor install.

My expectation of an "engineer-install" would be for a perfect install so that the line runs as fast as possible, but this is almost certainly not the case here.

It is possible the original install was good, but a previous resident retro fitted some extra extensions

If they were to fix it because of the phone line, would that even change the speed?

Fixing the voice issue may help improve the VDSL speeds

Test socket tests are key to determining where fault may lie

Hi,

So I unscrewed the socket and plugged this phone into the test socket and rang it.
It didn't ring, but was able to pick it up and hear the other end just fine, but wasn't able to hang up on the DSL's end, only my mobile.

A receiver never has been able to terminate a call, only the initiator can do that.

Try dialling the mobile from your house phone, then you should be able to hang up.

Point is, plugging it into the test socket made no difference.

You need a ring-signal on pin 3 then. Does it ring with the master socket fully assembled?

No it does not. We have one port in one bedroom, another in another bedroom, one in the hallway and one behind the TV (Master Socket).

The one in the hallway doesn't appear to functional at all, there's no noise / indicator on the phone that it's actually on.

As for the rest though, noise is heard through the phone if you pick it up but simply doesn't ring.

You unscrewed the small bottom half and did you also remove the VDSL faceplate to expose the real test socket?

If any of the other sockets in the house had a dial tone then your wiring is wrong
