2 Overview Level-Set Similarities Technical Differences Architecture Differences Principle Differences Shifts in RTC

3 Voice Over Internet Protocol VoIP a Broad term Grown to encompass multimedia, not just voice Diverse protocols some well defined standards, some de-facto, some proprietary Used in a variety of networks IPv4, IPv6, Public Internet, Private LANs, etc. SIP

4 The VoIP Universe UC Business VoIP Fixed Line Consumer VoIP Mobile VoIP IMS

5 Web Real Time Communications Plugin-less RTC Media engine in the Browser Purpose built for the World Wide Web Collaborative W3C and IETF standardization RTC as a feature, not necessarily the service or application

6 WebRTC Universe 1B devices Supported in 1Q14

7 User Experience Legacy 100 Years of Telco 20 Years of Web Reliable, Secure, Resilient Rich, Dynamic, Innovative
