4G Americas, a wireless industry trade association representing the 3GPP family of technologies, including LTE and LTE-Advanced, has published the white paper, VoLTE and RCS Technology Evolution & Ecosystem, which describes in detail the recommendations and best practices for Voice over LTE (VoLTE) and Rich Communications Service (RCS) implementations and offerings. VoLTE supports higher quality calls and faster call connections, and in combination with RCS, provides new features in three major service areas: telephony, messaging and contact management.

4G America said that VoLTE is a business solution that provides operators with a complete solution to evolve their voice business towards an all-IP communications network. This is achieved by evolving the installed base circuit switched core network towards an IP Multimedia Subsystem (IMS) core network, which supports communication services like High Definition (HD) voice, video calling, Wi-Fi calling and RCS services, added 4G Americas.
