Published on

The presentation "Quality over WebRTC" was presented at the WebRTC conference in Paris, http://bit.ly/19E3w5o. The presentation looks at the quality challenges in WebRTC as communication over the open internet and how this is different from current VoIP communication.
Later the presentation reviews Tools that can help minimize these issues as well as a WebRTC network federation option managed by a cloud appliance that optimizes the communication for cost and/or quality.
