Inter-Tel Introduces Enterprise(TM) Conferencing and Enterprise(TM) Instant Messaging Solutions

SIP-Based Collaboration Tools are Robust, Cost Efficient and Designed to Allow Businesses to Enhance Communication, Improve Workgroup Performance and Increase Profitability

TEMPE, Ariz., Oct. 21, 2003 -- Inter-Tel Incorporated (Nasdaq: INTL) today announced the release of both its Enterprise(TM) Conferencing and Enterprise(TM) Instant Messaging solutions, two SIP-based collaboration tools that are engineered to improve communication and productivity between geographically-dispersed colleagues, customers, partners and suppliers.

"The introduction of both the Enterprise Conferencing and Enterprise Messaging applications is just one example of Inter-Tel's commitment to leverage IP communications to develop applications that enable businesses to improve their processes," explained Craig W. Rauchle, chief operating officer of Inter-Tel. "As designed, these solutions may expand an enterprise's communication capabilities, to allow them to become more efficient and more productive."

A SIP-based solution developed for converged communications environments, the Enterprise Conferencing application provides both audio conferencing and web conferencing components. Requiring no changes to an enterprise's infrastructure or firewall, it provides a low-cost, secure method to share sensitive information with colleagues, clients, customers and other partners. It allows team members to collaborate on documents and other materials, record presentations for future use, and quickly respond to urgent needs by creating "on-the-fly" conferences and training sessions. In addition, the Enterprise Conferencing tool integrates with the calendar functions in Microsoft(R) Outlook, and features a browser-based user interface.

Inter-Tel's Enterprise Instant Messaging tool is a browser-based solution that combines instant messaging with the ability to make telephone and conference calls. As a result, organizations have the ability to communicate immediately with mission-critical parties. Requiring no additional client desktop software, the Enterprise Instant Messaging client enables users to create contact lists, send e-mails and instant messages, and convert instant messages into phone calls when needed. In addition, the Enterprise Instant Messaging delivers enhanced security through its embedded encryption capability, and provides users with a resource to track and audit communications.

"The introduction of the Enterprise Conferencing and Enterprise Instant Messaging platforms is a perfect example of how Inter-Tel uses new technologies to develop advanced, practical solutions that address business needs," said Jeffrey T. Ford, chief technology officer for Inter-Tel. "We are committed to building on Inter-Tel's leading SIP capabilities with applications such as Enterprise Conferencing and Enterprise Instant Messaging designed to help our customers be more productive."
