Much has been written about media servers and their benefits.  In this two-part blog, I’d like to talk about this cool infographic we developed to discuss the roles of media servers for both operator and enterprise applications.  All sources cited in this blog are noted on the infographic.

For more on media servers, check out a great article titled Media Servers Will Play an Increasingly Important Role for Telco Apps recently published in Internet Telephony magazine by colleague Jim Machi.  The article discusses the critical role of media servers today.  Additionally, there are numerous posts in the Dialogic blog about media servers.

Media servers power modern real time communications – plain and simple.  They are the foundation for applications built on video, WebRTC, interactive voice response, prompts/playback recording conferencing and speech recognition.  All of us interact with these technologies every day, whether through our mobile devices or land line phones.  The purpose of this infographic is to show how critical media servers are across the communications spectrum.

Let’s take each of the sections one by one.

Mobile 4G Networks with VoLTE and VoWiFi

Mobile operators use media servers to deliver critical and profitable applications to subscribers.  Operators are moving to Voice over LTE and Voice over WiFi to deploy enhanced applications to drive increase revenue, and contain costs.  Today there are more than 50 million subscribers running on VoLTE and that number is expected to grow to over 1.2 billion subscribers in the next five years. 

Operators are looking to offer differentiated serves based on VoLTE and VoWiFi.  Each of those ways to deliver voice and video services is based on 3GPP’s IP multimedia subsystems (IMS) architecture.  It’s in that specification that the media server is defined as an MRF (media resource function) to deliver voice and video.

MRFs provide HD audio interworking, automated announcements and prompts, touchtone (DTMF), recording and playback for voicemail, and advanced video features.

Mobile and Web Apps with WebRTC

WebRTC is the new web and internet standard that is defining a new age of app-based communications for web and native mobile environments.  See my earlier blog on a WebRTC conference in May.

We all know it’s all about mobile.  But did you know that there are expected to be over 6 billion mobile devices which will support WebRTC by 2019? Today, there are more than 600 companies using WebRTC for a wide range of services including customer service, support, education and finance.  Additionally, there are more than 4000 open source contributors to WebRTC making this a widely adopted and solid platform to deliver advanced real time communication services.

Media servers provide multi-party conferencing for audio and video; recording with real-time playback; and interworking with existing telephone networks.

Enterprise Unified Communications

Today’s enterprise workers are increasingly mobile, and so are there communications systems. And these communications systems are increasingly cloud-based. More than 63% of large enterprises have at least one unified communication application in the cloud.  This drives the growth of a $12 billion hosted VoIP and UC market by 2019.

Media servers provide voice mail servers, speech processing, multi-party conferencing and audio and video, recording and real-time playback, interactive voice response services, and WebRTC interworking with existing networks. 

In my next blog we’ll focus on media servers in video conferring, contact center and next generation 911 services.
