Extended home , Do I need a landline for the extend home to work
Welcome to the Community!
You do not need to pay for a landline for the Extend Home Adapter to work.
You use it to extend one of the numbers on your Republic account. While you do pay for the adapter up front, there is no monthly charge for using the adapter.
In addition to what @johnny5 provided, RW has a help section with additional documents on the Extend Home.
There are other articles listed on the right side of the page. Hope these can answer other questions you might have.
We love our Extend Home!
