Voxeo Labs' Phono WebRTC Gateway Gets DTLS Support

With WebRTC still being so young, new advancements are made nearly every day. For example, a number of WebRTC gateways were recently announced from the likes of Huawei and Mavenir while, more recently, Voxeo Labs effectively made its Phono jQuery plug-in the first WebRTC gateway with support for Datagram Transport Layer Security (DTLS).

"Phono makes it easy for developers to create cross-platform communications applications. Having DTLS support is crucial for interoperability between different browsers and devices. Server gateways must support DTLS to enable integration into existing communications networks," said Jose de Castro, CTO of Voxeo Labs. "The Phono Gateway brings Web-based real-time communications to carrier's IMS and legacy networks in a secure, easy-to-implement way."

Phono allows developers to create real-time communication in Web browsers and on mobile devices via WebRTC, Flash, Java, iOS and Android. Meanwhile, the Phono Gateway allows differing endpoints to communicate with each other, while also acting as a bridge to SIP, mobile and the public phone network.

Phono is the first WebRTC gateway to support the DTLS standard, which was recently mandated as a required transport layer for WebRTC audio and video. With this support, telecom operators can integrate WebRTC into their networks, while also enabling developers to write applications that interoperate between WebRTC and other platforms.

Furthermore, by enabling Phono to support audio and video encryption through the DTLS standard, Voxeo has contributed the DTLS implementation to Bouncy Castle, the leading library for cryptography in Java or C# applications. Voxeo Labs collaborated with Bouncy Castle's developers to add DTLS APIs into the standard libraries, allowing developers to build client and server applications that interact with WebRTC.

In other words, Voxeo has provided developers of WebRTC products a well-tested and secure implementation of DTLS.

"Security is hard to get right and the impact of getting it wrong is enormous. Inclusion in Bouncy Castle means developers can be confident utilizing DTLS in their products," said Bouncy Castle developer David Hook.
