In “Voice over LTE” scenario, voice calls will be typically provisioned over a 4G LTE data network and not on the circuit-switched 2G or 3G networks that are normally used.

The VoLTE technology allows the voice to become another app that uses LTE data network. LTE, which is also known as Long-term evolution is the technology standard for delivering high-speed broadband services, that are commonly known as 4G.

VoLTE depends on the IP Multimedia Subsystem (IMS) network. 

Benefits of VoLTE
