Your Ethernet ports on your modem tell me you likely have a 4 port built-in router.

VOIPo sends you an Analog Telephone Adapter (ATA)


  • The VOIPo ATA plugs into one of these four RJ45 ports (ATA WAN port)
    (A bit bigger than a phone jack port.)
  • The phone can plug into either phone jack on the ATA
    (If you have two phones they can each use a port so you can have two separate outgoing calls at the same time.)

You can talk after the ATA has booted and successfully been provided an Internet address from your modem/router.

EDIT: It is mostly plug and play if you ISP is typical.

VOIPo support via chat or phone could likely walk you through the hook-up.
