Hi Team,
We are facing issues about VOIP call for some users in USA who used the Wi-Fi network of some service provider. They are not receiving the calls on Wi-Fi but able to receive the call when connected to SIM/Data Connection. We implemented the VOIP services of apple and VOIP notification received and call kit UI displayed. Its working fine on public network mostly but not working on some Wi-Fi network in USA.
iPhone 12
Latest iOS version
VOIP notification not received
Call kit not display
App Name=> Owwll
