Hi,
There is another option:
Having 1 OBi device in the US and 1 OBi in China. From China-OBi device, call direct to the OBi-US (dialing **9 + OBi's 9 digit numbers) to get the Auto-Attendance. Both OBi devices must be added under the same login email profile at
www.obitalk.com portal for this setup.
Auto-Attendance will prompt for "Continue this call..." or "Make a new call".
This setup will not use Google Voice Service.
Best Regards,

This is basically what I was suggesting, but without the Auto Attendant. You can easily route calls over the OBiTalk network without the Auto Attendant with just a few configuration changes. I should have been more specific with my above post.
