Sonus WebRTC Gateway (WRTC) is a new technology that enables web browsers to participate in audio, video, and data communications, without any kind of additional plug-ins or application downloads. Using a WRTC enabled browser, user can place a call, participate in multi-party video and audio conferencing, and engage in screen sharing collaboration. Sonus Web Service Solution bridges the web and SIP worlds to facilitate the integration of communications (voice, video, and data) in applications.
Sonus SBC is a component of Sonus Web Service Solution. Sonus SBC provides media service functionality when WRTC endpoints are behind a NAT.
