Does anyone have it working with google voice in canada? Is this possible?
Google Voice is a USA-only service; there are no Canadian Google Voice phone numbers.
There are plenty of other good, low-cost options for using an OBi device in Canada. Check out voip.ms, which is a Canadian-based SIP VoIP service provider. Callcentric is another good choice.
I do.
You can't sign up from Canada, so I signed up when I visited the USA. (You could also use a proxy/VPN/SSH tunnel.) Once you sign up, the service works from Canada.
