Trying to find phone solutions for my Phonak hearing aids

When it talks about the KS10. That is a rebranded P90 as well.

Phonak P90 landline phone connection

I am trialing Paradise P90. I think that they don’t “connect” to a simple landline phone and they need a bluetooth landline phone. Is that correct, or maybe my audi is missing some connectivity program ?
