Guys my comment was all about the bugginess of their software. Nothing to do with design and it was 2 years ago. Alot changes overtime.
Secondly I feel it would be wrong of me to comment on something now since we have our own phones so my impressions are going to be bias.
As far as our phone looking like yealink the Sangoma Phones have NOTHING to do with Yealink except they are also manufactured in China like almost everyone else now days and their are only a handful of quality contract manufactures of phones. In the end what makes the phone is the software which is what sets our Sangoma Phones apart as long as quality parts are used for the audio portion such as Mic, Speaker.
