I am in the UK. EE is now my provider for the internet and my digital phone.

The "EE Smart Hub Plus" they provided does not supply IPV6 connectivity (my old BT hub did). I know, it's 2025.

So I bought this VX1800v. The internet is working fine (not tested IPV6 yet, but it should be OK, I think)

The problem is my digital phone, which is plugged into the phone socket of the tp-link.

I have dial tone, but it doesn't work.

I need help setting up the "Telephone numbers" Page.  

EE have not been able to help me except to tell me that the "Registrar address" is probably EEi

I have entered my phone number.

The status is reported as X which I read as 'failed'.

I think I now need entries for

Registrar port

SIP Proxy

Any suggestions will be gratefully received.
