Connect a landline phone to Livebox 5

Hello,

The "Sagemcom HD" is a television decoder... not a phone... So, you should provide the brand of this phone and its model so we can find our way...

There is one, the D49 https://boutiquepro.orange.fr/telephonie-multi-lignes-telephone-hd-d49-pour-livebox-pro-v3.html
Which is a VOIP phone (over the internet) compatible with Live Box 3 and Play and 4 but there's no information on the LB5,

You may need to activate the function.... who wouldn't it be..??

Otherwise, the vast majority of cordless phones operate around a "BASE" that must be connected behind the LiveBox, to the "Telephone" socket

That's it, but to be relevant, you need to know the exact model of this phone.

Ah yes..! Well, here’s what was missing, a simple explanation... Our reader must not have gone through the manual..?

Hi,
otherwise, we can still connect the base to the box via cable, after all ...
that makes two options, which is a lot for someone who is struggling.
Actually, is this phone Wi-Fi not DECT?
oh well, it's DECT ...
we really like incompatibility at Orange, not reassuring ...
The connection method looks like a Wi-Fi connection (WPS)
