5. When Voice Meets Video – How SIP and H.323 Can Coexist

When Voice Meets Video – How SIP and H.323 Can Coexist. Presented by Gernot Scheichl, Edgewater Networks.

As enterprises continue to embrace videoconferencing as an important business tool, h.323 remains the predominate protocol in use for these business-class room systems. At the same time, UC systems that integrate voice, video and collaboration features, such as instant messaging and desktop sharing are mainly SIP based. Similarly, the consumerization of on-demand video services using WebRTC, while not requiring a specific signaling standard, are also moving toward SIP so they can easily interconnect with VoIP service providers. The challenge is in developing an ecosystem where the legacy installed base of h.323 enterprise videoconferencing can seamlessly interoperate with the newer SIP based video offerings.

This presentation will review strategies for managing this interoperability, including developing a network that supports both protocols equally, and deploying the proper tools for interconnection between the two protocols. While operating two separate signaling networks has been effective and will likely continue, this session will focus on strategies to ensure protocol mediation, security and QoS without compromise for either protocol. It will review how single, integrated appliances possibly can support both networks while simplifying network operations and reducing costs.
