Landlines are NOT disappearing, if you have the internet, which if you are posting on here you probably do, all that happens is that the phone(landline) is plugged into the back of the hub instead of the wall. You will not notice any difference. The only drawback is if there is a power cut, then you may be with out your land line and if your mobile is not fully charged you will have no means of communication EXCEPT that you will, because you will also be provided with a back up battery for the hub and phone. I have just had mine done two weeks ago, landline is plugged into the hub, it’s now called digital voice. Do not notice any difference. So, just saying, in case some people are fearing that they will be without a landline, you won’t be.
