Pre-integrated solution gives Vonexus customers a cost-effective, reliable, and complete IP telephony solution BOSTON, INDIANAPOLIS and LOD, Israel, Sept. 19 /PRNewswire-FirstCall/ -- Fall VON 2005 Conference & Expo -- Vonexus Inc., a wholly-owned subsidiary of Interactive Intelligence Inc. (NASDAQ:ININ), has combined its 100 percent Microsoft-based IP PBX with AudioCodes (NASDAQ:AUDC) voice over IP media gateways for a cost-effective, reliable, and complete IP telephony solution. (Logo: http://www.newscom.com/cgi-bin/prnh/20041025/VONEXUSLOGO ) The Vonexus IP PBX, Enterprise Interaction Center(R) (EIC), helps customers leverage and protect their technology investments by providing an end-to-end IP telephony solution that lets them keep dial tone providers and existing phone numbers, while taking advantage of sophisticated computer telephony software applications running on an open, session initiation protocol (SIP)-based server with the widest available range of pre-integrated Microsoft back office and desktop applications. Combined with the AudioCodes gateways, which provide the required network elements that enable connectivity for external calls to the PSTN, Vonexus customers get the added flexibility and cost saving benefits that come as a result of running these applications from their corporate infrastructure to branch offices without deploying additional telephony equipment. Under the terms of the agreement, EIC can be purchased with AudioCodes analog MediaPack(TM) gateway products, and its digital Mediant(TM) gateway products. "This partnership enables Vonexus customers to install the AudioCodes gateway directly into the IP PBX server, thus eliminating costly additional equipment and easing overall system administration," said Lior Aldema, vice president of marketing for AudioCodes. "We chose AudioCodes VoIP media gateways for their superior voice quality, competitive price points, and reliability," said Jerry Fleming, president of Vonexus. "AudioCodes extensive product line has enabled us to offer complete flexibility to meet our customers' requirements, while providing a tightly integrated, highly-tested, and mature IP telephony solution." Vonexus completed certification of the AudioCodes media gateways this month, and the integrated solution is currently available through the Vonexus global channel of IP telephony value-added resellers and master distributors.
