Powered by new wireless and IP technology, we live in an increasingly connected world. Now we expect to be able to access services anytime and anywhere and seamlessly move between locations. Oh, and the quality needs to be great—everywhere! With the advent of Voice over Wi-Fi (VoWiFi) and Voice over LTE (VoLTE) and a range of supporting technologies including the Enhanced Voice Services (EVS) codec, Internet Multimedia Subsystem (IMS) and new “carrier-grade” Wi-Fi standards, providers are now able to deliver next-generation voice services with unprecedented quality and accessibility.
Over the past few years, Spirent has worked closely with the industry’s first round of providers rolling out next-generation voice services. Based on this experience, Spirent has developed best practices for assuring the successful launch of next-generation voice services with a focus on VoLTE, VoWiFi and EVS-enabled voice services.
This whitepaper details the key challenges providers face as they launch these services and shares Spirent’s recommended best practices and lessons learned. The whitepaper also illustrates key principles with test results of next-gen voice services from actual operational networks.
