I am waiting for my ISP to provide a Digital Voice service together with FTTP.

I understand that there are four ways of connecting to the service:
[1] plug a 'phone into a router port; or
[2] connect a DECT 'phone to the router wirelessly; or
[3] connect a VOIP 'phone to the router wirelessly; or
[4] download an Android app and connect using that.

The ISP does not provide telephone instruments.

Would there be a voice quality difference between [2] and [3]?

What wireless protocol does a VOIP phone use to connect to a router?

Can old DECT phones connect to routers, not aware of that facility.

You are missing option 2.5 which is an adapter for a DECT phone as never heard of option 2

1-4 all should have the same quality. We use VOIPFone and have done for years and there is no notable difference between 2-4 (sub apple for android). As not provided for by our ISP option 1 isnt open but 2-4 are equal, if not better to option 0 of using a landline.

The router data includes the following: "The FRITZ!Box 7530 also includes a telephone system for modern IP-based connections. The DECT standard allows you to create a telephone system with up to six cordless phones. There are also ports for connecting your analog telephone or fax machine. Plus, you have multiple answering machines, online telephone books and various convenience features at your disposal."

Thank you. That is exactly what I wanted to know. Number [2] then looks like the best option for me. 

Please, do you know whether each of my three DECT handsets need to be separately connected or does one DECT 'phone still act as a base station for the others?

The Fritzbox 7530 has an inbuilt DECT base station. Each handset is registered separately and you can register up to six handsets.

That is a very clear answer. Thank you for your help.
