Sansay recently announced a next-generation session border controller (SBC) and developer program designed to help service providers create enterprise- and carrier-grade WebRTC applications and services. In their announcement, Sansay pointed out that, according to Google, more than 1 billion PCs, smartphones, tablets and other endpoints now support WebRTC and by 2016, Disruptive Analysis predicts the installed base will hit 3.9 billion.
Sansay's WebSBC architecture is designed to deliver a carrier-class Media Engine and scalable WebRTC-SIP interconnect. WebSBC is an evolution of the VSXi SBC, a platform already being used by over 350 service providers worldwide, according to the company.
When we followed up on the announcement with Jerry Ryner, CTO and co-founder at Sansay he said that the evolution is a natural progression for his company which already delivers an SBC capable of managing 20,000 queries a second. He described the WebSBC as a “border element between the app and a SIP network.” (Note: SIP can be used by WebRTC as a session control protocol). He noted that the device is already undergoing interoperability trials to show how WebRTC’s browser-based calls can interoperate with other SIP-controlled calls in service provider networks.
Since WebRTC enables browser—to-browser calls can bypass the PSTN, we asked Ryner whether carriers consider WebRTC as a threat or an opportunity. He said “WebRTC has everyone’s interest, and [service providers] are strategizing to find out how they can adopt [WebRTC].” He believes that the best approach for service providers will be to offer enhanced reliability and advanced features, and that enterprise users will take advantage of WebRTC, even if it means they have to switch web browsers to do so. (Note: Microsoft and Apple do not yet support WebRTC, Firefox and Chrome do).
Ryner envisions more feature-rich “wow” apps coming out with support from WebRTC, and believes that SIP and IMS may be too cumbersome to support some of the emerging apps. And he intends for Sansay “to play a big role in making that happen.”
