Techopedia Explains Voice Over Long-Term Evolution

VoLTE primarily works on IP-based networks and only supports packet switching. The data received from a circuit-switched cellular network such as the Global System for Mobile Communications (GSM) or a Code Division Multiple Access (CDMA) network will be converted into network packets before being broadcast. VoLTE uses IP multimedia subsystem (IMS) based networks to offer these services. It will not work on networks that are not compatible with or that have not integrated IMS within their core architecture. The services that can be provisioned using VoLTE include video calling, voice calling, and multimedia streaming and sharing services.
