Is it possible to pair their Phonak Paradise 90 hearing aids to a Snom D725

From what we have researched, we have found a Bluetooth dongle that could possibly support Bluetooth connectivity, however that would use up the sole USB slot in the phone, so they would be unable to make calls.

We are still trying to find a possible way for the user to have all eh needs, so he can hear a phone call straight into his ear with the aid.

Is this possible? Are there any avenues that we are missing? Can you advise?
