Selsius Systems, Inc. was organized in July, 1997 as a wholly owned subsidiary of Intecom,[2] a Dallas-based PBX (Private Branch Exchange) manufacturer, with David C. Tucker as CEO, Richard B. Platt as VP of Engineering and Kevin Brown as VP of Sales and Marketing, as well as numerous other important positions held by the employees of Selsius Systems including John Alexander, Paul Hahn, Dave Corley, Jeff Sanders, and Scott Veibell.

Selsius Systems was borne out of Incite, a division of Intecom, which was a wholly owned subsidiary of Lagardere SCA, a French conglomerate.

[citation needed] While Incite's distributed call control software architecture was innovative, the market for a high-end video PBX was not responsive.

[citation needed] Following the acquisition, Platt and Tucker were retained as Cisco executives in the IP Telephony division, directly overseeing the product they helped to create.

The CallManager product was still in need of significant work when acquired, often referred to internally within Cisco as "CallManagler" because of its immature feature set.

The book was authored by original Selsius (now Cisco) employees John Alexander, Chris Pearce, Anne Smith, and Delon Whetten.

A Cisco employee, Mark Nelson, has a blog post devoted to Selsius, including photos of the key players Platt, Tucker, Alexander, Sanders, and Hahn.
