I have two Obi200s that I use with two google voice accounts. They had been working fine since August, but starting last week I had intermittent trouble making and receiving calls on both of my Obi200s. When making a call I receive the error message "...has not received a response from the service provider." Following the troubleshooting guide, I put one in the DMZ, but that did not help. I have no trouble making and receiving calls directly from my computer. Sometimes one Obi device works but the other does not. The echo test **9 222 222 222 works. Tech support told me to transfer my number to a new google account and then transfer it back. I have not done that yet. What will that do? What could cause this?
