I use a commercial Asterisk-based SIP provider for my business. I'm going through the process of acquiring hearing aids, and it may be smartest for me to steam telephone audio from my provider directly to my aids via bluetooth and a softphone (I spent a lot of time on the phone). I could conceivably use my Android handset, but it seems k,ind of clunky. I used to use X-Lite under Windows, but the Linux version is very rough comparatively. I've also tried Xoiper, but find the interface pretty rough. I want something that's close to a phone dialing and usage wise.
Counterpath makes Bria and Eyebeam, which are more contemporary then X-Lite, but there is apparently no way to try them out (I would be open to buying one if that made sense).
Any recommendations are appreciated.
