Digital voice adapters compatible with Vodafone

Hello.  I have just switched from BT to Vodafone FTTP with Digital Voice.  Does anyone know how to make BT Digital Voice Adapters ( connect to a Vodafone router?  I am just seeking a means to connect the various wired telephones that I have around my home to the router so that I can still use them, as I did when I was with BT.  I have one telephone hardwired to the router but that just leaves me with one functioning telephone in the whole house.  Quite what the benefits of this Digital Voice system are, I do not know!  It is just a real pain in the backside!  Thanks in advance for your advice.


If you still have the original phone wiring in place, that is the wiring used before you went to full fibre (FTTP), you should just need to run an RJ11 to BT cable between one of the TEL ports and a BT socket. (Something like this 3m RJ11 to BT Modem Cable Lead Telephone Phone Plug BT Socket 2 PIN Crossover 5060457589539 | eBay)

Or use the "internet" cable that came with the router and something like this RJ11 to BT Plug Adaptor - Connect ADSL DSL Cable to BT Telephone Phone Socket 5060457589744 | eBay

It might be prudent to disconnect the incoming feed from the master socket, just in case it is still connected back to the exchange.

I have to say I haven't tried this, as I don't have FTTP (and not likely to for at least 2 years) but can't see why it won't work.

I got back to Vodafone - they told me that you can only plug a VOIP phone into the router. 

Now that is definitely wrong.

You can not connect a VoIP phone to the TEL sockets on the router, I don't understand why they tell people that.

The TEL sockets connect to an ATA (Analog telephone adapter) built into the router.

Rather than have the cost of adapters for different phones in different rooms you should invest in a set of cordless DECT phones.  They connect wirelessly to a Base Station which has the only wired connection to the router.  We have used a quad set of Gigaset DECT phones for many years, chose anyone brand and handset that you like.   Our main phones are connected to a special 4G router as calls are cheape for usr that way.  If you later go to a different Voip supplier the phone base will plug into the VoIP device
