RVSN Raketnye Voiska Strategicheskogo Naznacheniya (Russian strategic rocket forces) ) has announced SIP functionality in its popular viaIP MCU (1) (MicroController Unit) A computer on a single chip. See microcontroller.
(2) (Multipoint Control Unit) A device that is used to moderate a videoconference of three or more end points (users at computers or groups of users (Multipoint Conferencing Same as teleconferencing. This is a rather redundant phrase, because conferencing implies three or more participants, rather than point-to-point between two people. Unit).
This new SIP functionality enables point-to-point and multipoint voice and video conference between SIP-based video communications devices and legacy IP (H.323 signaling protocol) and ISDN ISDN
in full Integrated Services Digital Network
Digital telecommunications network that operates over standard copper telephone wires or other media. (H.320 signaling protocol) end points.
The SIP functionality of RADVISION's viaIP MCU was publicly demonstrated at this week's VON (Voice On Net) in San Jose, CA in the Microsoft Developers Pavilion, supporting videoconferencing between Microsoft Windows Messenger SIP-based video end-points (laptops). The RADVISION SIP MCU will be generally available worldwide in Q2, 2003. Additionally, because it is a software upgrade, this functionality will also be available at the same time to RADVISION's existing installed base of MCUs for an additional fee.
The RADVISION viaIP MCU, now with SIP functionality, is a key component in a videoconferencing infrastructure solution, enabling enterprises to both move beyond point-to-point conferencing and multimedia collaboration to include multiple parties in a single session and also act as a bridging and conferencing device to enable SIP-based end-points (such as Microsoft's messenger) and H.323/H.320 entities (such as video room systems) to communicate.
Leveraging RADVISION's advanced architecture, every port in the RADVISION SIP MCU can be dynamically used to support either an H.323 or SIP call, thereby avoiding the high cost of purchasing and provisioning additional, protocol specific, ports or an additional protocol-specific MCU.
"RADVISION was the first in the industry to demonstrate SIP-H.323 interworking (standard) interworking - Systems or components, possibly from different origins, working together to perform some task. Interworking depends crucially on standards to define the interfaces between the components. , at Spring VON 2001, as an emerging application for providing seamless, end-to-end connectivity in multi-protocol IP/ISDN communication networks," said Avinoam Barak, General Manager of RADVISION's Networking Business Unit. "For enterprises and carriers that plan to deploy voice and video over SIP, H.323, and ISDN, the interconnection of these disparate networks into a unified environment will be a necessary feature of any MCU being installed in the future. Our announcement of a market-ready SIP MCU is significant for the industry and fulfills this need."
SIP is an Internet Engineering Task Force (c/o Corporation for National Research Initiatives (CNRI), Reston, VA, www.ietf.org) Founded in 1986, the IETF is a non-membership, open, voluntary standards organization dedicated to identifying problems and opportunities in IP data networks and proposing technical solutions to the (IETF See Internet Engineering Task Force.
IETF - Internet Engineering Task Force ) protocol that has been gaining momentum in multimedia communications, as evidenced in Microsoft standardization on SIP for the video and voice in its Windows XP-based Windows Messenger application. RADVISION worked closely with Microsoft and other companies to define specific media control extensions to the SIP protocol, enabling enhanced visual communications functionality, both in the end point and the MCU. Additionally, the 3GPP GPP Government Performance Project

GPP Generic Packetized Protocol has defined SIP as the standard for supporting 3G wireless end points. With the emergence of 3G video phones, the RADVISION video telephony MCU, with SIP functionality, will address this growing market.
"Equipped with unique voice and video features, the viaIP MCU, now with SIP functionality, enables enterprises and service providers to build a powerful visual communications architecture for today's network and be assured of future operability Operability is the ability to keep a system in a functioning and operating condition. In a computing systems environment with multiple systems this includes the ability of products, systems and business processes to work together to accomplish a common task such as finding and with new, emerging protocols and end points for video telephony," Barak continues. "The support of SIP is a further step in RADVISION's vision of enabling videoconferencing and multimedia collaboration to any user, over any network, using any device, whether IP, ISDN or 3G wireless."
viaIP MCUs are built on the strong foundation of RADVISION's market-leading H.323 embedded software, ensuring full H.323 compliance and unmatched interoperability with ISDN, PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S. , cellular and IP networks, and with existing and emerging communications protocols, such as H.323, SIP, MEGACO See MGCP/MEGACO. , 3G-324M. With a viaIP MCU at its core, rich media networks deliver consistent and reliable performance with any device or protocol.
Conference sessions can be managed and configured on-the-fly with an intuitive, Web-based interface that offers easy, high-level conference control and administrative flexibility.
RADVISION's viaIP MCUs ensure exceptionally low latency and delay, for the most reliable, robust multipoint conferencing performance in the industry, driven by powerful algorithms that ensure unmatched video processing and quality. Relying on packet-based communication between system components, viaIP MCUs deliver maximum network uptime and reliable, stable performance.
The SIP MCU is scheduled for availability in June of 2003.
