My mother in law bought Magic Jack to get rid of her phone but she doesn't have internet service. She's 85. I think it's going to cost her more in the long run to get internet, etc.
I recently got an idea about having a phone run through my PC.(to have my own line for myself) At the moment I've theorized that I could connect the phone to the jack on the computer, use my internet as service(Using a wifi dongle)
and getting a number for my PC or Phone? Do I need special software or some sort of adapter? I would like to keep this as cheap as possible, if not free.
