Solutions for Mobile Operators

Mobile service providers are constantly evolving their networks to enable High definition (HD) voice and video communication services such as VoLTE, ViLTE (video over LTE), VoWiFi (voice over WiFi) and RCS (Rich Communication Services). As the demand for IP multimedia communications services grows, the desire to have high quality and secure real-time multimedia communication experience increases. While HD Voice implementation on mobile networks was a huge step towards that goal, the next generation IP communication infrastructure is transitioning to support full HD Enhanced Voice Services (EVS). EVS promises to revolutionize the voice communication experience with unrivaled quality, reduce cost of service, and open up doors for new service opportunities to mobile operators.
