CISCO SYSTEMS COMPLETES ACQUISITION OF ACTIVE VOICE CORPORATION

SAN JOSE, Calif., February 15, 2001 -- Cisco Systems, Inc. today announced it
has completed the acquisition of publicly held Active Voice Corporation of
Seattle, Washington. The acquisition of Active Voice supports Cisco's vision to
deliver unified communications and a single, end-to-end IP network combining
data, voice and video for the corporate enterprise.

On Nov. 10, 2000, Cisco announced a definitive agreement to acquire Active
Voice, a leading provider of Internet Protocol (IP)-based unified communication
solutions for the enterprise. Cisco paid approximately $266 million in stock for
Active Voice's Unity(TM) operation, comprised of IP-based unified communication
solutions. Additionally, Cisco paid approximately $30 million in stock to Active
Voice shareholders for Active Voice's circuit switched PBX voicemail solutions
business, which was immediately sold by Cisco for $30 million to a newly formed
private company. This business will continue to operate under the name "Active
Voice, Inc." and will be comprised of a group of former employees of Active
Voice Corporation.

As a result of the acquisition, each share of common stock of Active Voice
Corporation will be converted to 0.57960 of a share of Cisco common stock, and
Active Voice stock options will be converted to Cisco stock options on the same
basis. The acquisition is being accounted for using purchase accounting.
