jio Wi-Fi calling

Wi-Fi calling feature.

Some users have out of the box enabled Wi-Fi calls, others are struggling to activate this feature.
I have also activated in Samsung A 50.
It was claimed by enabling Wi-Fi calls IUC charges will vanish. (Truth is it has nothing to do with IUC charges, It will remain the same as regular calls).

Enabling this feature call recording will not work as far as Samsung A 50 is concerned.
