Is it safe to assume that this is a brand new, factory-sealed unit you purchased from an authorized seller, or is it used? If it's used, it's possible that it is still assigned to the OBiTALK account of some other user.
This is going to sound nuts, but sometimes the OBiTALK system has problems over the weekends. Given that your device can call the 222 222 222 echo test number, it's probably fine. I'd suggest enjoying the rest of your weekend, then power-cycle everything on Monday and try again.
