Telecom operators face numerous challenges in their core communications business. We are past the point of "peak telephony" while VoLTE deployment is slow and patchy. End-users are fragmenting their use of voice and video, as "best of breed" applications emerge, while other software and websites embed new forms of communications with WebRTC. Telecom and cable operators have a large role to play here - they too can extend, build or resell WebRTC services, sometimes standalone, and sometimes linked to their existing network infrastructure and IMS platforms. Yet WebRTC highlights the organisational challenges for operators - reconciling different business units & service domains, and changing their culture to embrace developers, design-led mentality & more acceptance of risk. But with 6bn+ WebRTC devices expected to be in the market by 2019, telcos have a huge addressable market.
