Voice-Net Chooses Combined Priority/Centigram Solution; One Number Application Provides Enhanced Services to Voice-Net Subscribers and Creates a Virtual Office for Mobile Workers.

DALLAS--(BUSINESS WIRE)--March 26, 1996--Priority Call Management, a leading provider of intelligent telephony systems, today announced the selection of its one number communications platform by Voice-Net / Voice One, one of the largest privately held voice/fax messaging service bureaus in the Midwest. This announcement, made at CTIA Wireless '96 marks the first implementation of one number solutions for Voice-Net's expanding wireless market.

Priority has joined forces with Centigram Communications Corp. (NASDAQ: CGRM), to offer the MobileManager wireless application, leveraging the combined capabilities of Priority's ORYX platform and Centigram's proven AIP technology. (Note to editors: see related Centigram announcement.)

With MobileManager, Voice-Net provides the Personal Number solution which bundles voice, fax, and "follow-me" applications into a single telephone number. With Personal Number, calls made to a subscriber's telephone number can be simultaneously routed to the subscriber's mobile, office and home telephones, pager, facsimile, and other programmed communications devices. Callers have the option to hold for subscribers or be transferred to voice mail, while subscribers can choose to answer a call or transfer it to voice mail or another number for assistance.

"The key to remaining competitive in today's deregulated marketplace is to deploy a telecommunications platform that will provide the best flexibility, scalability, and reliability for quick delivery of new enhanced services to subscribers. With ORYX and MobileManager, Voice-Net is better equipped to deliver new services such as one number communications," said Andrew Ory, Priority's Founder and President.

Founded in 1988, Voice One, Inc. designs and markets voice and fax messaging applications. In 1990, Voice One, Inc., was purchased by Ambassador Communications, Inc. and the name Voice One and Voice-Net was adopted. An agreement in 1991 to purchase the voice mail division of One Call Communications, the fourth largest long distance provider in Indiana, made Voice-Net the largest privately held business-to-business voice mail service provider in Indiana.
