In most cases you will be able to plug a compatible existing phone handset or cordless base station directly into the NBN™ connection box (NTD) “UNI-V” phone port or an Analogue Telephone Adaptor provided by your phone service provider. Ask your preferred phone service provider which port to plug your devices into. Your phone may need a converter or a new cable if it has an old connector plug and your service provider will be able to confirm this. When the service provider technician has completed the installation, and reconnected your phones to the connection box, check that you telephone service is working correctly before he leaves your home.
