The answer depends on what type of connection comes to your place. You should be able to keep your existing phone number when moving to the NBN, but do check with your ISP.
- Existing fixed wireless or satellite connections: you shouldn’t need to upgrade your equipment for the NBN. If you’re getting a new fixed wireless or satellite connection, check with the ISP about what equipment you may need.
- Fibre to the premises (FTTP), where you’re getting fibre direct to your house: you’ll need a new router, but you shouldn’t need a new phone. Your existing phone should plug into the NBN connection box in your house.
- Fibre to the node (FTTN): you’ll need a new gateway (modem/router) from your ISP, but you should be able to plug your existing phone into the gateway. If you don’t want the internet and just require a phone service, you’ll still need the ISP gateway to connect to your existing phone to use the VoIP phone service over the NBN.
