AudioCodes and Clarent Show MGCP Interoperability of High-Capacity Media Gateway and Remote Call Agent Companies Demonstrate Pure Implementation of IETF Standards at Networld+Interop (Yehud, Israel & Redwood City, CA) – May 6th, 1999 – AudioCodes, a leading provider of IP Telephony and voice-over-packet enabling technologies, and Clarent Corp., the worldwide leader in carrier-grade, phone-to-phone, IP telephony solutions, announced today that they will demonstrate the interoperability of the companies' products using the new IETF Media Gateway Control Protocol (MGCP). Clarent will be demonstrating this integration at the Networld Interop show in Las Vegas, at booth #5031. The first use of MGCP by the companies will be demonstrated by a media gateway containing an upgraded version of AudioCodes' award-winning TrunkPack/VoIP-200 60-channel communications board, controlled remotely over an IP link by Clarent call agent software. This is the first time that a digital trunking device is demonstrating the "gateway decomposition" principle, the ability to divide VoIP transmission functions between the audio streaming device and a separate control agent. The MGCP protocol is an evolving IETF standard designed for controlling telephony gateways by a call control element. Further information about the MGCP is available from the IETF (www.ietf.org) "The ability to separate the voice streaming and call agent functions allows us to create a much wider feature set for our customers," said Shmuel Bachinsky, director of VoIP board products for AudioCodes. "We believe that the development work done by Clarent and AudioCodes shows the industry's first pure implementation of carrier-grade MGCP technology," said Mike Vargo, Chief Technology Officer of Clarent Corporation. "Our work with AudioCodes clearly follows our vision of providing carrier-grade, interoperable IP telephony technology through a flexible, intelligent network architecture." About the TrunkPack-VoIP/200 The TrunkPack-VoIP/200 provides VoIP packet streaming for 60 ports in a single PCI slot. Standard TDM bus interfaces, such as MVIP or SCSA are available for integration with other CTI products. An on-board NIC interfaces the IP network based on a standard RTP/RTCP media streaming protocol. An optional dual E1/T1 interface can be used to connect to the PSTN, with on-board signaling support. Twelve AudioCodes VoIP DSP chips perform all voice band functions for 5 ports each. The VoIP DSP features include G.723.1, G.729A, proprietary NetCoder™ voice compression and G.168 compliant echo cancellation. The board supports G3 fax relay, silence suppression, DTMF detection and VoIP IA 1.0 relay.

Frank - Have you had time to read the article entitled "Routers For Real-Time Applications" in the May edition of SoundingBoard Mag at soundingboardmag.com I found it an interesting discussion of how older routers have become the bottleneck for VoIP and the different ways in which the equipment vendors are attempting to deal with voice packets and data packets on the same network. Nortel wants to strip off voice over IP traffic and dedicate a VPN or virtual circuit to it on the backbone. Parallel processors and small packet handling are discussed. Ken
