-- RightFAX Enterprise 6.0 Provides Users With the Benefits of Redundancy and Clustering Safeguards, Enterprise Fax Management Tools,

and Paging/Short Messaging Support --

KIRKLAND, Wash.--(BUSINESS WIRE)--March 18, 1999--AVT Corporation (Nasdaq:AVTC), a leading provider of enterprise computer telephony solutions, announced today that it has upgraded the fax portion of its unified messaging platform to the company's RightFAX 6.0 Enterprise Fax Server.

"Since our acquisition of RightFAX Inc. in early 1996, the integration of the RightFAX server as part of our CallXpress unified messaging solution has been a key differentiator of our product in the marketplace," said Joseph A. Staples, AVT Senior Vice President of Worldwide Marketing. "With the integration of RightFAX 6.0 we are further expanding on the capabilities and value we deliver our customers."

The CallXpress unified messaging platform offers users all the functionality they need to send, receive and manage all of their voice, fax, and email messages in their Microsoft Exchange/Outlook or Lotus Notes inbox -- providing true unified messaging. In a single telephone call from anywhere in the world, CallXpress offers users the ability to listen to their voice messages, email messages, which are converted to speech, and forward any fax or email message to the fax machine of their choice. Users can also forward fax messages with a voice mail attachment, providing users with added functionality to improve communication. In addition, all three message types can be easily accessed through a single telephone number and a single set of commands.

The CallXpress administrative client provides an integrated subscriber configuration for voice and fax. New subscribers added to CallXpress are automatically set up as a fax user.

RightFAX Enterprise 6.0 offers administration and maintenance features that enhance support within enterprise environments -- complimenting the new AVT CallXpress Enterprise solution, which is designed for large multi-site customers. The RightFAX Enterprise Fax Manager (EFM) allows multi-server management for centralized administration of all RightFAX servers on the network. With the click of a button, administrators can view the status of every fax server; start and stop fax services individually or globally; determine server workload; and configure least cost routing (LCR) rules.

In addition, RightFAX introduces server-side application conversion (Serial Systems Architecture) for Office 97/2000 file formats. This new technology better preserves the intricacies of special fonts, embedded graphics and other complex formatting. For the Enterprise customer concerned about reducing single points of failure, RightFAX Enterprise 6.0 includes the ability to distribute essential fax processes for redundancy and load-balancing purposes. The same features also offers the ability to maximize hardware in clustered server configurations.

Paging and alerting support have also been added to RightFAX Enterprise 6.0. This support enables administrators to receive alerts about fax server status via their pagers. It also allows users to receive pages or short message notification for a variety of events such as new faxes received and new faxes received from specific senders using Caller Subscriber Identification (CSID) or Automatic Number Identification (ANI).
