ANNAPOLIS, Md.--(BUSINESS WIRE)--Nov. 22, 1999--

USinternetworking, Inc., (Nasdaq:USIX), the leading Application Service Provider (ASP), and Genesys Telecommunications Laboratories, Inc. (Nasdaq:GCTI), the leading provider of enterprise interaction management (EIM) solutions, today announced a partnership to deliver interaction management solutions in conjunction with USi's Siebel customer relationship management (CRM) offering.

The combination of Siebel's CRM applications with Genesys' Internet interaction management, computer telephony integration (CTI), and routing solutions provides customers with multiple options for communicating with call center agents, including email, the web and traditional phone. The solution allows call centers to operate more efficiently, while enabling call center agents to instantly identify a caller, quickly obtain a complete customer profile to resolve the customer's sales or service need, and access historical information to gain a more complete view of ongoing customer communications.

Under terms of the agreement, USi will offer and host Genesys' software, including its award-winning Internet Suite and CTI solutions. This partnership better enables USi to provide a one-stop-shop for its customers' needs and lends added strength to its Siebel solutions. USi's expertise in application integration enables rapid implementation of Genesys' software in USi's state-of-the-art data centers. In addition, USi's dedicated CLIENT Care team and 24x7x365 client support means that companies no longer need to hire and train additional IT staffs to manage these business critical applications.

"For USi, the value of this partnership is the seamless integration between Genesys' software and Siebel's customer relationship management applications. Genesys is a Siebel premier partner and is Siebel '99-approved," said Wes Johnston, vice president, Siebel Consulting and Engineering for USi. "Genesys offers an enormously robust solution for managing customer interactions and provides a comprehensive tool set for rapid, repeatable implementation."

"USi has a proven ASP model with a high quality of service in operations, implementation and support," said Nick Talbott, vice president of North America Channels, Genesys. "Our relationship with USi reflects our commitment to establishing best-of-breed partnerships that enable our joint customers to realize the benefits of a fully integrated, multi-media customer contact center solution."

By attaching important data such as a caller's address, account number or customers' contact history to individual calls, Genesys' software arms sales and customer service agents with critical background information that enables them to be better prepared for incoming customer calls. Regardless of the communication channel, the interaction can be routed to the appropriate agent through intelligent multi-media routing to ensure that every customer call is handled by the most appropriate agent depending on skill, availability, workload and service level agreements. The result is more efficiently routed calls, decreased customer wait time and shorter, more concise customer interactions.
