Sorry, I confess my troubleshooting skills are thin.
I began using a different internet provider, and in the process of changing, reset the OBi200. Now, when I try to make a call I get the message: "the number you have dialed [xxxx] has not received a response from the service provider."
When I look at the OBi Dashboard, I see that the device SP1 says "Registration not required"
I'm not sure what to do with this. Suggestions?
