In Egypt, the Obi110 DOES register with GV, says "Connected" on the ObiTalk dashboard, but I get no incoming calls.
When I use Gmail via a web browser, I get no "Call Phones" function in the chat panel.
If I do the same thing using a US IP address via a VPN service, I DO get the "Call Phones" function.
On the same gmail account, if I go back and forth between US IP and Egypt IP, the "Call Phones" function appears and disappears.
My incoming SIP calls work fine, and outgoing GV calls work, but incoming calls don't (Google Voice number ringing Google Chat) which makes me think that Google is doing geolocation blocking... which sucks.
