We use a CISCO IP phone series 7912 at work. I have a hearing problem and am using Phonak hearing aids. Are there any Bluetooth "gadgets" that can connect my phone to my hearing aids? Many thanks.
Since there are wide variation in hearing aids, and types of hearing loss, there is no guarantee that any specific phone make or model will provide perfect sound quality or will be compatible. but you can refer the below link once, it lists the compatible headsets to work with Cisco phones.
