I have been trying to get VoWifi working through my GT-AX6000 (with VoLTE already enabled). The router is pretty much standard Asuswrt Merlin, with latest firmware (3004.388.7), NordVPN and a DuckDDNS script. I know that VoWifi works on my phone because I can use VoWifi on another router at another location. On the Asus router, when I make a call with VoWifi enabled on the phone, the call gets through and runs for about 21 seconds before being cut off. I suspect the timing is when VoLTE attempts to hand over to VoWifi.
My phone is on the Telstra network (Australia) and according the page referenced below, I need to disable NAT acceleration. IPSec passthrough is already enabled on the router.. I have also tried with SIP passthrough enabled and also disabled with no success

My question is whether there is an easy way to disable NAT acceleration and whether there are any suggestions for me to try to get VoWifi
