Summary

This chapter talked all about the evolving technology standards in the telecom domain and their usage in the context of WebRTC. We provided insight into RCS and its feature implementation in the WebRTC web client, such as enriched call experience, converged phonebook, unified messaging, and service discovery, among others. We also discussed the RCS-enabled SIP Server for the WebRTC client.

In addition to this, we briefed on JOYN, which is a standard to embed RCS features in an end user device. We also shed some light on VOLTE, which is an access-layer technology for faster speed in the IMS environment.

In the upcoming chapter, the compatibility of various browsers, SIP softphone, and mobile applications to WebRTC standards will be gauged. We will also discuss the methods to bridge the gaps in enabling communication between WebRTC browsers and SIP devices.
