The article provides information on the Internet Protocol Private Branch Exchanges (IP-PBXs). IP telephony is rolling out at a rate of 25,000 to 30,000 IP endpoints per month as per the market researchers say. The article further compares five IP-PBXs namely OmniPCX Enterprise system by Alcatel SA, Avaya Inc.'s S8710 Media Server and the G650 Media Gateway products, Cisco System Inc.'s latest IP Communications System, featuring the MCS 7845H-based Call Manager, ShoreTel's ShoreTel5 system and Siemens AG's HiPath 4000. Notably absent from the high-end players this year was Nortel Networks Inc. Nortel was invited but respectfully declined, citing lack of resources. The new test plan by Miercom was built on hard, objective task accomplishment, reducing the potential for testers' subjective grading. Procedures were also adopted to ensure consistency in portions of the review involving management, architecture and features. While Avaya emerged the overall winner in the "Best in Test evaluation," Alcatel got the category award of "Best-Performing IP-PBX, Large Systems." INSET: Testing Large IP-PBXs.
