We've been advised that the phone line will be transferred to the hub next month and have received an adpater to plug for connection into the hub. We have 3 extension sockets which need to be kept live.
I've seen from other posts that a 4 Wire Plug to RJ11 Crossover Telephone Cable could be used to back feed the extension sockets from the master socket. What's the signifcance of crossover? I have retained a cable from a disused phone which has a RJ11 plug at one end and a normal telephone plug at teh other; can I use this?
Welcome to our Community Forums! Thank you for your post and for your query. We're here to help you understand our new Home Phone Switchover process.
Once the landline has been switched over to our new 21CV (twenty-first century voice) system, all phone sockets will no longer work.
If you're needed to have other landlines across your home connected, we'll be more than happy to arrange for a technician appointment so a technician can come out and re-wire the connections to ensure that you're still connected. However, this connection will be solely through our broadband Hubs.
We do have a Home Phone Switchover FAQ page where you can read through this to familiarise yourself with this new system.
Please let us know if there's anything else I can help you with.

The information in the link is very general and doesn't help me.
I'd be grateful for a response to the specific points in my post.
A RJ11 to BT plug lead can be wired 'Straight Through' (at each end pin numbers correspond 1-1, 2-2, 3-3 etc.) the 'Crossover Arrangement' is as below
3 * 5
4 * 2
* Line pair
Useful info here on connectors and pin numbering
Picture of an adapter lead VM have used in the past is here at message #9
The inclusion of a ringing capacitor somewhere in the wiring is required if you want to use old phones (early-ish 2000's and before) which may require this.
Various other 'how to' guides are on the forum if you want to DIY rather than get VM to do it for you FOC.
Perhaps too techy!
For those interested...
Our phones are plugged into extension sockets; nothing plugged into the master socket which is next to the router . The standard advice from VM isn't of use. I've disconnected the incoming phone wire from the master socket and used a telephone connecting wire with an RJ11 plug [into the router] at one end and a standard 4 wire BT type plug at the other end [into the master socket]. This connects the router phone signal back to our extension sockets. Didn't need to use the adapter provided by VM.
I done the same as Geoff and mines is now working as expected. Only difference with mine was that the master socket is downstairs and the hub is upstairs but next to an extension socket. I connected the hub to the extension socket via a normal phone cable and disconnected the feed cable from the street at the master socket in the living room so that there was no back feed into the street. All of my 4 existing sockets now work as they did before. Pretty easy to do yourself and no need to waste an engineer's time.
