DO I NEED A LANDLINE FOR THIS SYSTEM.
Hello, i'm new to this. My parents have a landline and it's always giving them trouble. So they call their phone company to have someone fix it, dig up the yard and so on. My parents are elderly and their phones even have cords. This looks great ,but does one pay for a landline. Or do you find a plan with a local company. Could someone please explain this to me. Thank You very much.
