Hi @Raymondwwchen, we currently supply TP Link VR1600v modem for our NBN services, except for NBN FTTP, which we currently supply TP Link C1200 router only.
The VoIP service that comes with the NBN internet bundle is only configured on the TPG supplied modem, thus, we advise our customers to use the TPG supplied modem if they want to take advantage of the VoIP service.
However, customers have an option to use their own modem if they are not going to use the VoIP service, provided that it is NBN compatible modem.
We don't have any recommended make and model of modems.
For the modem configuration part, you just need to make sure that the VLAN is enabled and the VLAN ID should be set to "2".
