Landline had been removed

[User110920]

It's come to my attention that Vodafone have decided to remove my landline and replace it with VOIP. Apparently, I just have to plug in my analogue phone to my router but the problem is I live in a four-story house. How am I supposed to connect all my phones to a single router? I'd like Vodafone to put back my analogue line. This behaviour is unacceptable. Now I have no phone line and was not told in advance. Thank you, Vodafone.

I see these Grandstream devices sell for anywhere between £50-£150 each. So I can just buy a few Grandstream VoIP phones and set them up with my original number? Is there any specific model that I need to buy. Or can I just port my landline number to another service provider? I need my original number.

I would combine it with @Jayach's suggestion and run all your phone wiring from a single ATA. It's beyond a medium skilled user to  share a single port (5065 in this case) amongst several ATAs.

The wiring would be exactly the same as using the vf router, just a different device.

I'm not familiar with VOIP terminology as I have never really used a VOIP phone or installed one. When you say, "ATA", this is like a box that converts all your analogue phones to run on the VOIP system?

Like the ones in this link?: https://www.lifewire.com/top-phone-adapters-3426340

So I can just buy an ATA, connect the master socket to the ATA and connect the ATA to my Netgear broadband router?

And do the setup of course, as discussed in the other thread. 

At the moment we can only support the Grandstream HT801 or HT812. Anything other than those two have so far not connected successfully. 

[User110920]

So if I buy the HT801, I just connect it to the master socket and the router and simply follow the installation instructions in the thread above? I'll be able to connect the three phones located on old analogue lines around the house?

[Ripshod]

Correct.

Thank you.

I just realized, I also have an alarm system that uses the phone line. If the internet or electricity goes down, the alarm will not be able to dial out. It's an expensive alarm so I don't want to replace it with a new one. Is there some kind of GSM converter to convert the line from the alarm to work over a GSM mobile network?

[Ripshod]

As that's a major concern look into getting a ups for just the router and ata.

How often does the electricity go out though? I haven't experienced any outages in over ten years.

Look for accessories for your system, there may be a GSM auto-dialler available. Or a portable 4g/5g modem/router.

My system is from around 2005. There are no accessories available. The other problem is internet outages which does happen occasionally. I don't want to rely on Vodafone broadband for the alarm to work.
