Business Editors

PALO ALTO, Calif.--(BUSINESS WIRE)--July 17, 2000

Callisma, a new network architecture services company specializing in helping service providers enhance customer experience, has recruited a notable ensemble of prominent networking and technology industry executives to lead the company. Callisma's two co-founders, president and CEO Ralph Troupe and vice president Steve Umphreys, have assembled a talented team to pioneer a new kind of networking consulting company focused on helping service providers transform their networks to deliver new services required in a multi-media, `always on' environment.

Callisma's executive team brings more than 200 years of networking and management experience to the company. This depth has fostered the company's rapid success and growth in just eight months from two to nearly 250 employees, 14 offices nationwide serving nearly 40 customers including companies like NaviSite, Inc., CTC Communications and PhatPipe, Inc.

"Callisma's executive team brings a unique level of depth and experience that will help service providers deliver new services that enhance customer experience," said Deb Mielke, principal of Treillage, a leading service provider consultancy. "The company has attracted the top talent who can architect the breakthrough infrastructure needed in the new, networked world."

Prior to founding Callisma, president and CEO Ralph Troupe served as vice president of International Network Services (INS), a services company that created the networking consulting space in the early 1990s and was acquired by Lucent Technologies in 1999. As a senior executive, he substantially contributed to INS' record growth and profitability both pre- and post-IPO. Troupe has more than 15 years of experience in the networking arena and is now focused on building Callisma into the leading architect for service providers as they deploy networks that provide differentiated services and always-on availability in the New World.

Rarely is a high-tech company founded by a human resources leader and Callisma co-founder Steve Umphreys' focus on team success, personal and professional development and retaining the best networking talent is testament to the company's commitment to its employees. Umphreys previously served as vice president of human resources for INS and contributed to INS' dramatic growth from 200 to 2400 employees. Umphreys has more than 20 years of experience working for high-tech companies such as Hewlett-Packard, 3Com and Octel Communications.

-- Gail Holmen, chief marketing officer, previously served as vice president
and general manager at INS where she was responsible for building and managing
INS' highly successful consulting services throughout the Northwest.

-- Tim Sparks, chief legal counsel, who was previously a partner at Wilson
