There is a 100% bug somewhere in current firmware. The Obi device was up for ~ 2 months at least. My Obi110 paired with GVoice. I used it as my home phone.
Yesterday all incoming calls started going crazy.
1. For me: after picking up phone I don't hear anything;
2. For callers: they still hear calling tones (as nobody picked the phone up).
Did experiments tens of times - from cell and landlines. The same problem.
After power cycling Obi110 is started working normal.
Clearly this is a signaling error.
