VoIP (Voice over Internet Protocol) services convert the audio signals of a phone call into digital data that travels over the internet. VoIP lets you call any landline or mobile number, but you will be using your internet connection to do so.

Once you have switched to the NBN, your old copper phone line will be disconnected. You'll then need to use VoIP if you want a landline phone service. Homes connecting to the NBN via Fixed Wireless or Satellite will continue to use the old copper phone lines for home phone lines for the foreseeable future.
