Do I have to have my computer switched on to make calls?

No, your computer does not need to be switched on to make calls.

IP phones plug directly into your broadband router giving them direct access to your Internet connection.

This means you do not have to turn your computer on to make and receive calls and you can use VoIP like a traditional phone line.

If you are using a softphone you will need to have your computer switched on as the software that is used to dial and receive calls is installed on your computer’s hard drive.
