Im thinking of purchasing a unifi switch and router and wondering if I will be able to still have my VoIP phones working if the original router supplied by optus is plugged into the unifi switch with its gateway set to the unifi router. I've seen similar posts on this forum but the optus router sits behind the byo router inbetween the NTU. I've made a very basic Visio diagram to try an make my idea clearer.

What you propose would work just fine, make sure you forward port 5060 at the IP assigned to the Optus router for your phone service to work correctly.
Optus doesn't supply the SIP details due to support boundaries, there is way too many ways to skin a cat when it comes to VoIP setups... and it's impossible to support every single outcome (especially for scripted support).
awesome. If you get a chance, can you tell me how you did that?
I've tried setting up a port forward rule via the unifi controller, but i must be doing it wrong.
Forward IP: 192.168.0.1 (optus router IP)
Forward Port: 5060
Yeah that rule is correct and the same as mine.
Make sure the IP of the Optus router is correct and that the it's connected to the switch via the WAN port on the back of the Optus router, usually a red colour not by one of the 4 yellow LAN ports
Excellent visio graph.
Do you set static ip on the LAN port or the WAN port of the Optus router?
Should port forwarding destination be the WAN port IP address or LAN port IP address of the Optus router. I guess it would be WAN port, since nothing except the phone is plugged into the Optus router?
Much appreciated if you can help me.
