While holding the promise of HD quality, enriched services, and the benefits of a common packet switched access infrastructure, the adoption of infrastructure-based voice over LTE (VoLTE), along with rich communications such as video and real-time messaging, has stalled over the last few years with concerns around quality, security, and cost. During that time, the value of the phone number as a globally significant user ID and key services such as SMS and MMS have been relegated by phone manufacturers, over the top (OTT) services, and even the subscribers themselves as “technologies of last resort.”
Finally, the proliferation of 4G, together with the emergence of network functions virtualization (NFV), powered by Intel, Hewlett Packard Enterprise* (HPE), and Metaswitch*, is allowing network operators to take charge of the consumer’s communications experience, once more.
