We had a phone system with a page port but have since got rid of the phone system and now have a VOIP system with an ATA. I purchased a PI-1A but it doesn’t seem to work with my ATA. Any help? : Viking Electronics, Inc. Online Support

The PI-1A is ONLY compatible with a Page Port or a vacant Trunk Port. (FXO)

ATA's come in a variety of configurations. If you are able to provision a FXO port on your unit, then you are good-to-go.

If the ATA is only capable of supplying a dial tone (FXS port), our RAD-1A or FXI-1A product would be required.

To make sure you purchase the correct product, contact our help line at (715) 386-8861 and they can assist you.
