WebRTC Gateway for Enterprise

Kandy Link, Ribbon's WebRTC Gateway (formerly known as SPiDR), provides an intelligent bridge between Voice over Internet Protocol (VoIP) networks and the open ecosystem of the Internet. WebRTC services enable enterprises to deliver communication services to employees and customers inside of existing applications or via a simple web-browser. As an example, Kandy Link provides a compelling way to web-enable contact center access, eliminating the need for customers to dial a separate toll-free number and reducing the need to traverse menu trees. Kandy Link performs a number of federation services to transform SIP communications to WebRTC or vice versa, so organizations can retain their SIP-based call control (PBX, contact center, etc.) and offer tools that embed real-time communications into business applications, websites, processes and workflows.

Scale and Resiliency

Kandy Link is built on a software base that serves carriers around the globe. That means it's designed for five 9s reliability, with redundancy and serviceability as part of the core architecture. This is in stark contrast to many of the open source projects in the market focused on niche deployments. Kandy Link is built to be a critical element in the call flow, ready to perform 24 X 7.


The Kandy Link gateway sits at the edge of the network and provides open, web-centric APIs that allow application developers to gain access to the enterprise's Unified Communications (UC) services – including voice, video, presence, shared address book, call history, instant messaging, and collaboration. Instead of having to write software to interface to every element, Kandy Link seamlessly and intelligently interworks both the signaling and media planes so developers only see a simple and secure set of web-centric APIs. Kandy Link takes the complexity out of accessing communication services.

Enabling WebRTC based clients

Kandy Link introduces Web Real-Time Communications capabilities into Ribbon's cloud-ready Application Server solution and offers WebRTC soft-clients that simplify the deployment of unified communications and collaboration. These clients include:

  • Smart Office - Ribbon's next-generation UC clients that deliver a stylish and intuitive UI that is dramatically less expensive to deploy and manage
  • Ribbon Real-Time Communications Client for Skype for Business™ - An innovative solution that allows enterprises to use Skype for Business for instant message (IM), presence and contacts, but still keep their voice, video and multimedia services on their Enterprise UC platform and provide contextual information (emails, calendar events, attachments, etc.) for incoming and outgoing calls.

Kandy Link facilitates the deployment of universal applications, drastically reducing both the CapEx and OpEx costs related to VoIP services for consumers and businesses. Designed using HTML5, CSS3 and Javascript, and leveraging Kandy Link's REST APIs, our clients provide a multimedia user experience that allows end users to easily access their services from any web-capable device using a web browser or deeply integrated with the operating system via Ribbon's patent-pending Omni Client Technology.

Vertical Market Solutions

Kandy Link allows enterprises of diverse market verticals to exploit the capabilities of their communications networks via simple, RESTful APIs. By partnering with other market-leading organizations and vertical market experts, Ribbon is delivering breakthrough custom solutions that allow its customers to increase productivity, contain costs, maximize revenue opportunities and win the battle for customer loyalty by delivering a superior customer service experience.

Enabling the Kandy Hybrid Cloud Solution

Kandy Link becomes a local extension of the Kandy CPaaS solution providing WebRTC gateway functionality and media broker capabilities and, in combination with the Kandy CPaaS, enables enterprises to deploy additional services in the network as micro-services (Mobile Push Notifications, for example).

Kandy Link goes beyond basic WebRTC gateway functionality delivering value-added capabilities that accelerate the deployment of new services keeping compliance with user data privacy/sovereignty and contribute to enhance the user experience and optimize the total cost of ownership.
