Hi I am planning on getting two obi202 to make free calls to a family member that will be deployed to Japan for 3 years. I know I can make free calls from device to device but my family member also wants cancel her Sprint cell phone contract and port her number to google voice to use with the obi202. She had a business that will be closed but she is still expecting a few phone calls from her former clients to the sprint cell number at least initially.
What configuration do I need to apply, if any, so that calls made in the US from a land line or cell phone to the google voice number ring on the obitalk device in Japan?
Will both devices need to be configured or just the unit that she will take to Japan?
