Hi @Ajm47 . If you use the TPG VOIP phone function, you have to use the router provided by them. If you don't use the phone, you could buy your own router.
If you have FTTP, the phone connects to the FTTP box, so there is no restriction on using any router.
If you have FTTB or FTTN connection, you need a router with RJ11 DSL port to connect to telephone wall socket.
