I guess no option to know if this setting is being used as well,
right??
Hmmm, I’m not sure I understand this. Are you referring to the second part of your original question:
I am also interested to know if we can find a way to know if Wi-Fi
Calling is being used in a call.
Is that right?
If so, I believe that the answer is “No.” There’s certainly nothing in Core Telephony that returns this info. AFAIK CallKit doesn’t return info about other calls but I’m not going to offer a definitive answer because CallKit isn’t really my bailiwick (a different engineer in DTS supports that API).
Share and Enjoy
