Is CAT 6 cable okay as a telephone line?

Battery backed up VOIP boxes are supposed to be available for people who rely on the land line phone.  But customers may have to specifically ask for one.

Most people have a mobile phone these days and would use that if the land line goes down.

HI Andy, I think the link I posted had both options, the "master" and "vanilla" via two order codes? But yes.

Of course that assumes the power cut does not affect the base station the mobile connects to.  - given the short range of mobile phones, after all the average transmitter power is only a fraction of a watt, you are likely to lose the mobile connection and mains and fibre pretty much all at the same time, certainly for an HV side fault or a rota power cut.

The final solution using bits out of my stock of cables and connectors was a secondary phone socket on both ends of the CAT 6 cable then a BT plug to BT Plug patch lead into the back of the Sky WiFi router, so the lift has an emergency landline phone connection that won't work during a power outage.

These lifts are built within the UK, the Chinese simply build a mobile phone into the control panel of their lifts, which is a simple solution so long as someone puts a SIM card into the phone and arranges payment for it, as well as changing the language on the phone to English.

One lady got stuck in her lift after her tea trolley wedged under it and the mobile phone display was in Chinese.

Wow Sparking, all this sounds a tadd concerning

The customers take on it is that they don’t actually use a landline phone anymore, they have unused phone extensions in the flat that are disconnected and a cordless phone that was turned off at the electric socket, they also always take their mobile phone when they go out so as well as using them at home, so will have them when they are in the lift.

I do wonder if I have run a fifty metre long phone line which may not actually be used or particularly fit for purpose.

It is probably also why it’s the first full landline phone extension I have installed in seven years, hence the moment when I had to stop and think about what I needed to do.

I did actually try connecting directly to the BT socket, but it only has an internet connection.
