ISG Navigator significantly shortens time-to-production for

enterprise and web solutions

ISG International Software Group, Ltd. (NASDAQ:SISG), a leading provider of B2B and e-Business integration solutions, today announces that Capital Telecommunications, Inc. (CTI) is using the ISG Navigator software as an infrastructure for integrating enterprise information.

Robert Smith, IS Manager at CTI commented: "The beauty of ISG Navigator is that it gives us an immediate way to bring diverse relational and nonrelational data from fragmented back-office applications together into a cohesive enterprise solution. Because we don't have to worry about integrating our enterprise systems, we can focus on our core business."

Using ISG Navigator, Smith's IT team has built a unified billing system and a web-based customer service application that both query, join and update relational and legacy sources with the same commands. The team leveraged those integration efforts to build a web-based system for independent sales agents, a project which required, "absolutely nothing on the data side," said Smith. "All we had to do was write the web pages."

Smith explained, "Given the current growth of our agents program and the average salary of our IS staff, The ISG Navigator-powered application will save us $200,000 that we previously budgeted for next year to support the new agents alone. We delivered the unified billing system in less than three months and the customer service application in less than five months. It would take years to achieve this level of integration without ISG Navigator."

Arie Gonen, chairman and CEO of ISG, concludes: "ISG Navigator enables telecommunications businesses like CTI to respond quickly and effectively to customer demands. We are very happy to be giving this industry leader a faster and more economical way to achieve a cohesive enterprise solution."
