Using a Google Voice number with OBiTALK may cause the OBi200 to display an OBiTalk token error. This is due to a problem with the GV on OBi. This error is caused by a software issue, and is usually solved by updating the device to the latest firmware. The OBi200 must be running version 3.2.2 of the OBiTALK software before it can display the OBiTALK token errors.
