SCO and Dialogic Announce the First Open CTI Server for UNIX Systems.

SANTA CRUZ, Calif. and PARSIPPANY, N.J.--(BUSINESS WIRE)-- Oct. 8, 1996--

Enables PBX Vendors, Developers, and End Users to Create Next-Generation Computer Telephony Solutions that Leverage Today's Voice and Data Networks

SCO (NASDAQ: SCOC), the world's leading supplier of UNIX server and host systems, and Dialogic Corporation (NASDAQ: DLGC), the world's leading supplier of open, standards-based computer telephony hardware and software components, announced today that they will develop, market and support Dialogic's computer telephony server software, CT-Connect, on SCO UNIX servers. The software, expected to be available in the second quarter of 1997, will be the first open, standards-based CTI server for the UNIX operating system, enabling developers to create integrated "single box" computer telephony solutions on an open UNIX platform.

Christopher Thompson, director and principal analyst at Dataquest, said, "By enabling integration with a variety of interactive voice response (IVR), call center, voice messaging, CTI workgroup, PC switch and private branch exchange (PBX) systems, this SCO and Dialogic software on the UNIX system platform will give customers the ability to leverage their existing voice and data networks while implementing next generation applications. These applications allow both companies' customers to provide services that meet their client requirements and expectations."

CT-Connect for SCO UNIX systems will support a comprehensive range of client application programming interfaces (APIs) and operating system environments. The SCO UNIX system-based version of CT-Connect will support the Microsoft Telephony API (TAPI) and Dynamic Data Exchange (DDE) interfaces at initial release, and subsequently the Novell Telephony Services API (TSAPI) interface. License terms and prices will be similar to other versions of CT-Connect.

"We chose to work with Dialogic because of their extensive support of SCO UNIX systems and the many strengths their Computer-Telephone Division provides," said Scott McGregor, SCO's senior vice president of products. "They are experts in supporting PBX call control development, they support the broadest number of PBX interfaces, and they offer independent implementations of TAPI, TSAPI, and other interfaces. CT application developers understand that customers want to leverage their extensive investments in UNIX systems, in order to take full advantage of their high performance, scalability and support for heterogeneous environments. When choosing a platform for the next generation of CT applications, UNIX servers are the obvious choice," said McGregor.

"A significant proportion of Dialogic's business consists of supplying computer-telephone technology to SCO UNIX system application providers," said Sam Liss, vice president of corporate marketing at Dialogic. "SCO has the largest installed base of UNIX server systems. CT-Connect software running on the SCO UNIX platform is just what solution providers need to enhance their applications with the integrated call control features customers require."

CT-Connect for SCO UNIX systems will support a wide range of telephone systems, including the proprietary link protocols used by the Lucent Technologies DEFINITY PBX and the Nortel Meridian 1 as well as the increasingly popular international standard CSTA link protocol used by Alcatel, BBS Telecom, Bosch Telenorma, Cortelco, Ericsson, Intecom, Mitel, Rockwell, Siemens Business Communications Systems, Tadiran and other switches.

The SCO UNIX system-based CT-Connect server will be available in four configurations:

-- A Full configuration, supporting all types of client modules and an unlimited number of client systems;

-- A Desktop configuration, supporting an unlimited number of client systems but restricted to desktop applications;

-- A Desktop Lite configuration, supporting up to 36 client systems running desktop applications: and

-- An Evaluation configuration, licensed free of charge, supporting up to 16 client systems running desktop applications.

CT-Connect has no usage-based license charges, and all client modules are included with each CT-Connect server at no additional charge.
