Wi‑Fi calling

[FCM]

Hello,

I've switched to 380.62_2 from stock firmware and I'm also missing WIFI calling on on iPhone SE and Orange. Will go to 62_1 and report on that.

You are not helping, bigcid10 ).

So, I was about to downgrade to 380.68_1 when I decided to play around with the settings in the "NAT Passthrough" tab.

It seems that at least in my case, it was about the "IPSec Passthrough" setting. As soon as it is off, Wifi calling is no longer available.

The other settings don't seem to affect the iPhone at all, but I decided to activate both H.323 and SIP Passthrough, just to be sure.

Problem solved, at least for me.

Just let you know;

WiFi calling uses UCP 4500 which is same with "IPSec Passthrough"

on your router's connections page you can see;

udp x.x.x.x:4500 x.x.x.x:4500 ASSURED

which stands for WiFi calling.

Excellent, problem solved then! Thanks.
