Exetel offers a FREE VoIP DID with every Residential VoIP plan that is purchased.
A DID means direct inward dial. This is your phone number. You can have more than one VoIP connection using the same phone number, at the same time.
What this means, is if you have two phone handsets connected, you are able to be on a phone call, and still able to make and receive phone calls on a second line.... with the same number.
You can opt for the higher value VoIP plans with cheaper call costs at the time of order, or at any other time during your service period with Exetel.
As the old copper lines are disconnected 18 months after NBN is connected in your area, you will need to choose a provider for the new system. You can stay with your existing provider if they have VoIP as an option, which most will do, or take a look at the savings to be made by changing to Exetel.
You will be able to retain your existing phone number and continue to use your existing phone. Nothing will change in your daily use of telecommunications equipment.
