Qwest Communications Awarded $10 Million Contract From Call Sciences

Denver, January 25, 2000 ? Qwest Communications International Inc. (NYSE: Q), the broadband Internet communications company, today announced it has been awarded a $10 million, three-year contract from Call Sciences?, Inc., a telecommunications technology company that supplies network operators, wireless carriers, resellers, and Internet service providers with enhanced telecommunications services.

Under the agreement, Qwest will provide Call Sciences carrier services, including domestic origination and termination, international termination, frame relay and Internet service.  With this new pact, Call Sciences has consolidated all its main services with Qwest, assuring the lowest rates for its customers and the reliability of a primary provider.

"Call Sciences is an innovative, global provider of enhanced telecommunications services that recognizes the importance of a reliable, high speed network to deliver its communications services to its customers," said Gregory M. Casey, Qwest's senior vice president of wholesale markets.  "Call Sciences' customers will benefit from the lower cost and reliability afforded by designating Qwest's fiber optic network as its primary provider."

In an environment where people now typically communicate via phone, fax, mobile phone, pager, e-mail and voice mail, Call Sciences manages all these applications on an outsourced basis from a Telco-grade, enhanced services platform that is scalable, reliable and economical.  This unified communications management service allows the customer to be in control of how and when they are in contact with others and enables network operators to attract and retain those customers despite a highly competitive marketplace.

"The relationship with Qwest is an example of our commitment to the future and system infrastructure for our growing customer base," added James Healy, Director of Product Management for Call Sciences. "Ovum analysts predict that U.S. demand for Personal Assistant and Unified Messaging Services will swell from nearly two million subscribers this year to more than 140 million in 2006. Qwest will provide Call Sciences with the voice, data and Internet networking we require to support this tremendous growth and maintain our price leadership position."
