No WiFI calling here... I mean, I have not even heard of that capability.
WiFi is available on many phones here. It uses the same protocol as VoLTE (Voice over LTE), but connects via WiFi. If the phone also has VoLTE enabled, it can transition seamlessly between WiFi and the cell network. VoLTE is essentially VoIP customized for the cell network and encrypted with IPSec. It is IPSec, encapsulated in UDP, that enables the seamless transition. https://en.wikipedia.org/wiki/Generic_Access_Network https://en.wikipedia.org/wiki/Voice_over_LTE -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
