Using a phone with a Digital Voice Adapter

[redders22]

I've just had full fibre (FTTP) installed with Digita Voice. I wanted to use my existing phones (geemarc amplidect 595) as they are designed for the hard of hearing. I connected them up to the green phone port on the smarthub2 and all works fine (no problems). However my problem is, along with the geemarc phones I had a "normal"/corded phone in one of the bedrooms. I tried to connect this corded phone up to the Digital Voice via a DV Adapter. When I rang my number all the geemarc phones rang but the normal (corded) phone didn't. Although it didn't ring, I can answer an incoming call using it and also dial out using it (if I pick it up I do get dial tone).

Any thoughts on this/can anybody help?

Welcome to this user forum for BT Retail phone and broadband customers.

The DV adapter only presents a two wire connection, and some phones need the additional "bell" wire to ring, i.e. three wires.

The missing third wire can be emulated by plugging a microfilter into the socket of the DV adapter, and then plugging the phone into the "phone" socket on the microfilter.

The microfilter has an internal capacitor which extends a third wire from the existing two wire connection.

@Keith_Beddoe    Thanks for the reply/suggestion. Just tried it and it works perfectly. Once again, thanks for your help.

Its probably why BT say that some older phones will not work. But as you can see, its an easy fix.
