Is the Green Square button suppose to call your own OBi ? It has a default speed dial setup and even when I enter the number manually **9123456789 (fake 9 digit obi#) and click "Call", it changes message to "Starting Call" and button changes to "End Call", but no ringing, and nothing changes in call dialog window. Thank you.
You should be able to call your own OBi. But it is unreliable. Some days it works, some days it does not. I've tried it several times just prior to typing this. Each time my OBiPHONE eventually rang but I could not get audio in either direction.
You need a browser that supports WebRTC. Reasonably recent versions of Chrome and Firefox do. I don't use any of the Microsoft or Apple browsers so can't say about them.
