Xchange Telecom Purchases Suite of Equinox Software to Support Nortel Switch Network & VOIP Infrastructure

Nashville, TN — October 3, 2006 - Nashville-based Equinox Information Systems today announced that Xchange Telecom, Corp., a New York facilities-based CLEC and broadband provider, has licensed a suite of Equinox software applications: TeleLink, Manager, and TeleScope.

Xchange Telecom selected the TeleLink mediation system to automate its call detail record (CDR) transmission process by filtering and converting call data for use by operational support systems (OSS). Manager monitors network performance and activity in detail by analyzing traditional switch as well as VoIP usage data, and TeleScope analyzes traffic from both a network and financial perspective.

"Equinox Information Systems offered Xchange Telecom the most compelling solution to address our operational support challenges" said Bob Charish, chief operating officer at Xchange Telecom. "By integrating the mediation and billing processes over both a traditional and VoIP network, Equinox software provides access to a real-time dashboard that gives us visibility into the quality and profitability of our domestic and international call traffic."

"This software purchase represents an important step in initiating a long-term customer relationship with Xchange Telecom / Sipmedia" stated David West, Executive Vice President for Equinox. "We have a great track record with companies like Xchange Telecom because our software systems interface seamlessly with Nortel switches and a VoIP infrastructure."
