WIT WebRTC Gateway

A bridge between WebRTC and Telecom

WebRTC Gateway

This product enables real-time communication between any browsers in the market without requiring any additional plugin installation.

The Gateway leverages the best use of WebRTC technology and provides the necessary conversion into Telecom protocols. It also enables real-time communications from the web browsers into smartphones, tablets, PC softphones, SIP phones and GSM/PSTN phones.

Message Plus

Works in All Browsers!

WIT WebRTC Gateway differentiates from other similar gateways in the market by trying to avoid the existing segmentation in the WebRTC market. The platform is built with a hybrid architecture, supporting the most recent WebRTC specification, as well as Adobe Flash media protocols to reach all the browsers in the market.

The Gateway provides support for:

  • WebRTC compliant browsers (Google Chrome, Mozilla Firefox, Opera) using Websockets and HTML5
  • Non-WebRTC browsers (Safari and Internet Explorer): the support is also based on HTML5, but makes use of Flash technology (RTMP protocol) for the transmission of audio and video.

WebRTC: Deployment Architecture

The Gateway can be deployed in an IMS infrastructure, used as a web front-end in front of the SBCs to conduct the necessary protocol conversions to the SIP world. To do the integration with RCS Apps, we recommend the installation of the WIT RCS Application Server as an AS in the IMS Core. With the necessary integration, it also allows the break-out of VoIP calls into CS calls and vice-versa.

Recommended System Requirements

  • CPU: 2 x CPU @ 2.66 GHz (6 cores, 12 threads)
  • Memory: 8GB of RAM
  • Ethernet Speed: 1000 mbps
  • OS: CentOS / Red Hat / Ubuntu Server (64bit)

Javascript SDK

We provide a Javascript SDK to create rich applications. It allows rapid application development, and provides several features to create innovative use cases.

This Javascript SDK abstracts the small differences in the WebRTC browser’s implementations. It also includes a Flash component to enable fall-back support for non-WebRTC browsers. To reach all browsers, we support WebSockets to establish bidirectional tunnels between browsers and the Gateway, for transport of the signalling protocol.

To know more technical details about our SDK, please check our developer’s portal.

What it is

Remote Assistant is a framework that helps Contact centers to provide premium assistance to the end-users who are using an app running on a smartphone, tablet or web-browser.

It provides a real-time communication channel between the end-user app and the agent’s front-end in the contact center.

The framework enables the agent to view the user’s screen, interact with the screen and make a video-call. With this tool the agent will be able to provide faster solutions to problems reported by the end-user.

How it works

The user can launch the Remote Assistant by pressing a button like the “MayDay” button from the Amazon Kindle. This action will place a call to the call center’s queue.

Once the Agent answers the call, a WebRTC session is established with the app from the end-user. From this point on, the user and the Agent can interact through an IP video call. If appropriate, the user may enable remote screen sharing with the Agent.

This way, the agent is able to remotely draw coach marks that will be displayed on the user’s screen to guide him through the app.

Features

  • Screen sharing
  • Video calling
  • Remote coach marks
  • End-user privacy with screen sharing opt-in/opt-out
  • Remote app control
  • Content sharing during the video call
  • IP chat
  • Real-time location sharing
  • Remote text highlighting
