Today, service providers have the need to transcode and interwork a multitude of voice codecs in their network. Whether it is to deliver Over The Top (OTT), modern fixed or mobile services, they are constantly evolving their voice networks to offer better and seamless user experiences for their customers. Selecting the right media transcoding and interworking strategy will not only benefit service providers with an increased bottom line, but also deliver ultra-HD quality audio to their customers while using less bandwidth and network capacity.

WEBINAR: Is your Network Ultra-HD Voice Ready?
VoLTE, EVS, and HD Voice
We have some very interesting topics to share with you today, starting with some quick market updates and overview. For instance, information on EVS transcoding which is offering ultra HD voice quality for your network. Why GPU-based transcoding? What are the business cases for enabling EVS in your network and what are the business cases to use GPU in your network? Also some interesting performance details on GPU based transcoding. We will share some details on the virtualized software-based transcoding at the core and wrap this up with the deployment scenarios and information or our proof-of-concept (POC) program.
So let me start off with the current telecom landscape, fundamentally, we all know that the telecom landscape is changing. In fact, the connected devices or the endpoint markets are growing rapidly. It's not just the devices market which is growing but invariably the pressure it puts on your network when new services, like VoLTE, and in future 5G services, which are going to be rolled out to your subscribers. So we definitely have more devices, more subscribers, and more real-time communication applications in the Service Provider Network. Obviously, with the growing number of users, the evolving network, the devices, there is a constant pressure for the operator,s such as yourself, to innovate and offer new next-generation services. A few things to consider, for example, how do you reduce the customer churn and bring in additional revenue per user? So we all understand you know your network is complex considering we have so many different services offered, whether it's fixed, TDM calls, mobile services like 2G or 3G, or all the way to VoLTE services. There are millions of such subscribers who are still subscribed to these services within your network. Most of the operators here are interworking between various services like Over-the-top (OTT), Unified Communications, VoLTE, and all the way to your fixed-line services all either within your network or between different network providers. With the current 5G initiative VoLTE deployment there is a case for operators more than ever to converge these different networks and experience and become flexible in offering or enabling new services for the future.
So what's common in these services offering? Like I pointed out earlier there are many of these services that you offer from your network directly to your subscribers. In most cases, you interwork all these services and also have challenges making sure you interwork between different operators without compromising on the call quality. Whether in the home network, a visiting network, or an operator we all know that the most common service here that ties all of these together is voice. So subscribers want or expect voice quality as a default expectation regardless of the endpoints or devices they are using. With 5G services introduction, the expectation of a clear ultra-high definition quality voice is definitely going to grow multifold. As a service provider, we have a few points that I would like to highlight. One is to offer Ultra HD quality voice service for the subscriber and their endpoints and second is making sure there is a clean interworking and media pass through without any limitation (things like call drops for your users). Last, but not least, a robust transcoding solution that lets you provide a seamless voice experience to your customer.
Why now you? What's the important importance of HD voice? Let's stop and understand the current VoLTE adoption rate and as well as the HD voice deployments across the world. According to GSMA, we have about 158 operators who have launched VoLTE as of October of 2018 and in over 78 countries. If you look at the LTE market, there are about 695 operators and 212 countries who have launched LTE services and HD Voice has been enabled in more than 164 operators across 88 countries. Given that the operators have invested a lot of time and money in the VoLTE networks and deployments, we all know services and handsets enabled with VoLTE infrastructure will be there for a very long time. There are two surveys that GSMA conducted with their HD voice subscribers recently, one is showing more than 70% of the customers choosing HD voice as the loyalty factor and the other one is saying that improve voice quality is greatly appreciated by most of these subscribers.
