WiFi calling requirements (Optus) Australia

[Vexira]

Which routers support this and how can I check to see if it's enabled
IP-SEC pass-through
Certificate Fragmentation support

I'm just curious.

Here In Turkey, I'm a Vodafone TR user and using iPhone x.

Here are my settings;

uPNP is also enabled but I don't think Wi-Fi calling is related any of these.

It's all related with your phone and operator. I can use wi-fi calling via android phone tethering over another operator which uses CGNAT. So depending on my experiences; you don't need any tricks to be done on your Asus Router.

Besides; mum has Xiaomi A1 which also supports Wi-Fi calling as far as I know but Vodafone TR does not support Wi-Fi calling for this model so mum can't use Wi-Fi calling.

I know that Telstra here volte works for all I know not could be working but Optus is a pain making it universal on supported phones.
