Dgital Voice in a power cut

[Starlored]

I'm considering getting full fibre with phone, i'm planning on using my own cordless phones with the Digital voice service.

By what ive read these obviously will not work in the event of a power cut, I noticed in the process of making the order BT offer a Battery Backup wich keeps the Digital voice powered for an hour, it also states that it come with a digital voice phone is this a solution  to make a call in a power outage.

As long as your hub and ONT are powered you will be able to make calls.

Whether they are powered by BTs expensive units or by a third party UPS system is irrelevant.

I thought that was the case, the only problem is my current cordless phones don't work without power.

Could you not pair your cordless phones directly to the SmartHub2 rather than their current base station?

That way, you will still be able to make calls for as long as the batteries in the handsets last - assuming you also have backup power for the SH2 (and ONT if applicable). You may lose some features of the phones though.

The Answer is probally, Ive had a search around the Internet and am confident of a soloution to make calls in the event of a power cut.

The simplest answer is to use a corded phone plugged into the green socket at the rear of the hub during a power cut with the hub and ONT powered by a UPS. Alternatively use the UPS to power the cordless base station as well as the hub and ONT.

The fact you using a cordless DECT phone currently, that you say you want to keep using should you move to DV and or FTTP , you presumably obviously are fairly relaxed about power outages or you would have a corded phone and not a cordless one ( obvious your DECT phone won’t work without mains ) so why does the prospect of FTTP/ DV cause you any extra angst ? , not having telephony during a power outages presumably is normal for you , irrespective of how likely a power outage is , so why do you need any extra precautions just because of FTTP/DV ?

No Angst I just want to get things worked out.

In the event of Putin pushing the button I want to know if I'm still able to call home.
