Ah, I have heard about these Obihai phones that support OPUS, but have not
tried them. How do the compare to a Polycom VVX phones?
The Polycom VVX 500 and 600 now support OPUS, but you must disable video. I
find that kind of silly as one of the main reasons to buy a VVX 500 or VVX
600 is the support of video.
What other phones and hardware devices today support OPUS?
