ViewCast.com Announces Viewpoint VBX™ Version 2.3

Support for PictureTel 4000 Series codec, Macintosh Environments and German Localization

Dallas, Texas -- August 9, 1999 – ViewCast.com, Inc. (Nasdaq:VCST) the company that offers high-quality video communication solutions, today announced the release of Viewpoint VBX™ Version 2.3. The Viewpoint VBX™ System provides a flexible video PBX architecture that manages multiple network and video compression types, delivering TV-quality video to hundreds of PC and Macintosh based desktops throughout an enterprise. The Viewpoint VBX™ can handle both broadcast and two-way video and is used for many applications such as videoconferencing, distance learning, corporate training, surveillance and telemedicine. When paired with the company’s ViewCast™ Internet Streaming Solution, the Viewpoint VBX™ offers a way for users to take any video application from the Viewpoint VBX™, digitize this high-quality analog video content, then stream it over the Internet.

The Viewpoint VBX™ Version 2.3 includes support for PictureTel (Nasdaq:PCTL) Series 4000 codecs and Macintosh clients. Support for the PictureTel 4000 allows corporations, educational networks and financial institutions to control expenses through the sharing of this resource. In addition, the Viewpoint VBX™ Version 2.3 has been localized for the German market and can be easily localized for other countries and languages. The Viewpoint VBX™ also supports H.320 (ISDN) and H.324 (POTS) conferencing codecs, and the company plans to support the H.323 (IP) compliant Osprey�-1000 codec in the near future.

"The Viewpoint VBX is a very flexible system that lets us incorporate high-quality video into our classrooms," said Jerry Davis, director of technology at Campbell Union School District. "The teachers and students are excited about the videoconferencing and other communication possibilities that Viewpoint VBX™ offers."

"We are pleased that our customers now have access, through the Viewpoint VBX, to the large installed base of business associates that are using the PictureTel 4000 Series and to educational environments that have standardized on Macintosh clients. These advancements make the Viewpoint VBX that much more valuable to any organization that relies on high-quality video for enhanced communications," said Bill Keever, Vice President at ViewCast.com.

Viewpoint VBX Release 2.3 Product Highlights

Viewpoint VBX Release 2.3 is completely internationalized. The internationalization process enables ViewCast.com to create VBX components for international markets, quickly and easily. As a result, VBX 2.3 includes the simultaneous release of Viewpoint VBX Server, Codec Manager, WorkFone VBX and WorkFone 320 components, in both English and German languages. In the future, other languages can be supported as demand grows. All language versions utilize the same software code base to guarantee interoperability. For example, a German WorkFone works with an English VBX Server and vice-versa.

VBX 2.3 integrates with ViewCast� Streaming Video Servers and G2 Codec Arrays. Using Osprey�-1000 G2 codecs, users can stream VBX video over the Internet or corporate intranet. For example, an executive can use WorkFone to access a ViewCast server attached to the VBX and stream video over the Internet from any desktop.

Codec Manager 2.3 supports PictureTel System 4000 codecs. Leveraging ViewCast.com’s powerful Codec Driver Model (CDM) architecture, WorkFone users can now access shared PictureTel codecs for placing and receiving calls. Also, PictureTel settings, such as audio levels and picture-in-picture (PIP) mode, can be adjusted in real time across the network using Dynamic Call Control™. Dynamic Call Control, an exclusive feature of WorkFone VBX, allows users to control codec settings during a call, from the desktop. In addition to PictureTel, Codec Manager supports ViewCast.com’s Osprey-1000 H.320 codecs, Osprey-1000 IP codecs, NEC VisuaLink H.320 codecs and C-Phone H.324 codecs. Also, Codec Manager will support Osprey-1000 H.323 codecs (in development) when they become available later this year.

VBX 2.3 provides new Automatic Call Distributor (ACD) capabilities, including an ACD Administrator application for managing video call routing. Using VBX ACD, incoming calls are queued and routed to available call center agents, automatically. In addition, an agent can transfer an incoming codec call to another agent, or conference the caller with another agent, without disconnecting the codec call. "Viewpoint VBX is the only system available that can queue incoming video calls, regardless of protocol, and route those calls among multiple agents in a call center," said Dave Stoner, Vice President at ViewCast.com.

VBX 2.3 provides Access Control capabilities, allowing system administrators to decide who can access expensive resources, including codecs and remote switches. In addition, system administrators can restrict access to other users. This allows system administrators to organize users based on customizable group profiles and access privileges. For example, video service providers can provide video distribution and videoconferencing services to multiple tenants in an office building. Users are grouped by tenant so that they may call other users within their group. Users in other groups are not visible in the WorkFone interface and, therefore, cannot be called.

The VBX 2.3 release also includes an updated VBX Server SDK for building custom client applications that communicate with VBX Server and a BETA version of the new WorkFone VBX for Macintosh, expected to be released in Q3-1999.
