Extend Range on digital voice phones?

[ImGoingSpace]

So we are in a pretty non standard setup with our new install and need a digital phone in a room that is currently too far from the hub location.

The hub cannot be moved closer and there are no existing copper lines to use with older handsets, which is a common answer i see when searching here.
Is there a range extender that can be used with the BT Digital phones? i understand that they are not standard Wifi so those extenders/mesh systems dont work.

(effectively the property is two buildings, hub is in one and need phones in the other building, at the far end of it.)

Unfortunately not. The phones are DECT rather than WiFi and standard DECT repeaters appear not to work with BT's implementation.

A workaround would be to use a Digital Voice adapter in a location nearer to the hub and then plug a a normal DECT base station into it and use a standard DECT handset.

sorry for my ignorance on the topic, i know nothing of phone tech!

i bought a set of BT DV phones, i can connect those to the adapter (wirelessly, DECT?) and then the adapter to the hub? if so, thats exactly what i'm after, the adapter acting as a range extender.

No, the DV adapter is basically just a portable analogue phone socket, it connects to the hub via DECT but not to DV handsets. You can't use it as a repeater hence by bodge suggestion.

Alternatively, just run a simple 2 wire phone cable to the remote location with an extension socket at each end and connect it to the green socket at the rear of the hub.

The DECT standard is typically 50m range without obstacles. But there are long range phones you can buy such as the BT Elements 1K. Or you could buy a set of phones that do support a repeater, try the DVA that @licquorice suggested & then have the repeater to fall back on if that doesn't work.

Probably best to speak to a specialist phone supplier like PMC Telecom, Ligo or OneDirect.
