WebRTC – Voice, Video, Screenshare

WebRTC – Voice, Video, Screenshare

Standalone  / Cisco Unified Contact Center Express (UCCX), Enterprise (UCCE or PCCE)

Expertflow's WebRTC implementation allows agents and customers to securely share voice, video and screen content. It doesn't require the customer or your agents to install any software - all that is required is a WebRTC-compatible browser.

Integrated into your website, mobile app, kiosk or digital signage device, WebRTC allows customers to establish an HD video session with an agent featuring, screen sharing, WWW activities and chat. A video session can also be initiated as part of a chat session  or a voice call. Agents use a Finesse Gadget to initiate a session.

Customers can be identified automatically using a cookie/ token on your website. 

Embed any Expertflow widget such as WebRTC, Callback or Chat with a single line of code, as a Wordpress Plugin, or Google Tag.

WebRTC to SIP gateway

Customers use the WebRTC capabilities of their webbrowser and webcam to interact with agents. Metadata (customer name, email,...) is captured from their browser via a tag management solution. On the agent side, voice and video is transcoded to SIP and forwarded to the agent's Voice/ Videophone. The screensharing element is available as a Finesse Gadget.

Available features:

  • Browser or SIP phone based voice and video
  • Browser based screen-sharing

Features with additional licenses

  • Hybrid Chat
  • file sharing
  • recording

WebRTC doesn't allow for

  • mouse or keyboard control
  • screen annotation, field masking, pointer

The customer identifies himself to the browser to the client's website. This browser in turn is associated to a customer profile in CIM using a cookie that will be stored in the customer's browser. The customer identity is transmitted through a tag manager data layer  on the website.

Transfer of customer data from website to callcenter

With Expertflow CIM, it is possible to capture customer data from a website before a WebRTC call, and transfer the same to a Cisco Callcenter as call attached data alongside the call.
Information is captured on the on the website using tag management , transferred to the WebRTC switch using RTCDataChannel, transferred to CIM , from where it can be read by CVP or Finesse and written as Call Attached data/ Peripheral Variables/ Expanded Call Context (ECC). Implementing this solution usually requires professional services of Expertflow.


This solution includes a ICE (Interactive Connectivity Establishment) server that can be located on the client's premises or using a public server for network address translation (ICE, STUN, TURN).

Agents can use a normal Cisco SIP phone (such as Jabber), or Expertflow's WebRTC client.
