About two days ago, I have been getting the error message "We could not complete your call. Please try again" whenever I make an outgoing call. And I can't get any incoming calls either. On the dashboard of my Obi account, it shows that sp1 is connected with my Google voice account. I didn't make any changes in my Google voice account recently to trick this. Rebooting the Obi 110 device (with firmware 'naf') a few times didn't help. Googling seems to indicate that this is a Google voice problem, but I have no clue to get this fixed.
Any suggestions? Factory reset?
