WiFi Calling - I need to prioritize this traffic

[georgeberz]

I'm lost how do I prioritize Wi-Fi calling on my phone? (android)

I work form home and cellular service does not work in my home OR place of business, we live on an island cell reception is sporadic at best and must use Wi-Fi calling.

Can someone show me how to set this up so my cell phone has 1st priority for wifi calling?

What protocols is it using?

If we do not know what ports to prioritize, then perhaps by IP address?

I gave my phone a static IP on the network.

Please help, I just downloaded the current version or OPNsense 24.1

Thank you

George

AFAIK it uses an IPSsc VPN. Check UDP ports 500 and 4500.

My family (4) we all use VPN's (PIA) on our personal computers, will those two ports do it and not interfere, I do not want their VPN traffic to get priority over wifi phone calls.
