Beltone Achieve with Landline Phone

I’ve been wearing HA’s for 15 years, exclusively Phonak. I am now trialing a pair of Beltone Achieve aids. Unfortunately the Clarity XL7BT Bluetooth landline phone I have that worked well (most of the time) with Phonak doesn’t seem to work with the Beltone aids. Is anybody aware of a Bluetooth phone that does work?

Beltone is using LE Bluetooth and MFi, your Phonak were using classic bluetooth, not sure if you could use some kind of bluetooth adaptors?
