I have an OBI 110 and 110 which for several months now have used google voice for dialing out via the Simonics Gateway. Now suddenly the OBI 110 stopped registering with the error message: "Register Failed: No Response From Server" error. The OBI 100 with the same password and settings (except for x1 extension) stays registered. I have tried removing and re-adding it to no avail. The strange thing is that I have not changed anything on my router or OBI110 when it stopped working all by itself. Any suggestions?
