VoIP Home Phone Service uses the internet for calling instead of using physical phone line infrastructure.
As shown below, the typical setup is your adapter attached to your router or modem, then your home phone device attaches to your adapter.

Alternative Setups

WiFi Extender

If your internet modem or router is not located in the same place you want your home phone device or base station, you can connect a WiFi extender to your WiFi network, which you can plug into any power outlet in your home. The WiFi extender will provide you with an ethernet connection for your HT-801 adapter.

Everyone’s internet speed, signal strength, and WiFi extender will be different, so we cannot support this setup. Attempt this setup at your own risk, we are simply letting you know it is possible.

Master Phone Jack

Plugging the VoIP adapter into your home’s master phone jack will allow all the phone jacks in the house to be connected to your Fongo Home Phone service. Your home’s master phone jack is usually found in the basement.

Anywhere you have an active ethernet connection, you can take your HT-801 adapter with you and use your home phone service there. With Fongo, your home phone number is not tied to your address, it’s tied to your adapter.
