Questions about FRITZ! Fon C6

Hello, picked up today and small charging cradle (as seen in pictures) with power plug included :-)

Does the Wingo router recognise the AVM FritzFon C6? Thanks for the answer.

I have a UBC provider, which Fritzbox do I need to use the phone?

I am looking for a landline phone (wireless) that I can operate on the Swisscom box via WiFi. And above all, I can synchronise my addresses with Outlook. Unfortunately, Swisscom has eliminated the Home App and has no replacement for it. So I can throw my HD Davos down the drain. Can't enter all the addresses all the addresses by hand. You'll go gaga...

Does the Fritz phone C6 have a retaining clip on the back so that I can attach it to my trouser pocket?

Can I connect this phone directly to the analogue connection of the UPC Connect Box or do I need a base station in between?

Hello, Does this offer also include a charger (charging cradle and mains plug)?
