VoLTE or VoIP over LTE?

VoIP has been in existence for more than a decade now. While it delivers toll- voice quality as expected in certain areas, it lags far behind in meeting user expectations elsewhere such as dynamically changing wireless environments. Over-The-Top clients have been delivering V.VoIP functionality over Wired DSL/cable since mid-90s and then over wireless WiFi/3G data networks since mid-2000s; they now also support VoIP over 4G/LTE mobile broadband networks. While mobile operators use circuit-switched for voice, with 4G LTE they have taken the VoLTE plunge, thus challenging OTT clients to deliver superior real-time video and voice. But who is the ultimate winner?
