Of course, this is a great feature, but it only works on the IOS platform and is not available to Android users. It is much easier for me to use a Business VoIP phone for a stable broadband connection. These phones offer many advantages over Wi-Fi callings. Since the Wi-Fi network is not always stable, there are some connection problems and the connection is not always of high quality. While using VoIP phones, I have never had connection problems and delays during a conversation. I agree that this function of the iPhone is well adapted for some users, however, it requires some changes and I am sure they will definitely be.
