General Notes
- Prior to contacting Support and if applicable, please verify the light status on the ATA. The power icon represents the power status, the World (Globe) icon represents the Internet connection status, the phone handsets with a 1/2 represents the fax machine connection(s). These status lights should be solid. If one or more of these status lights are blinking, it indicates an issue with that specific service.
- Ensure the fax (analog) cable is plugged into the LINE port of the fax machine and the Phone 1 port of the UniVoxx ATA.
- Ensure nothing is plugged into the EXT port of the fax machine as this is known to cause issues with some fax machines.
