Open source identity: Asterisk founder and Digium CTO Mark Spencer

Imagine an IP voice and unified communications system that can be integrated into any application and customised to meet business needs. Sounds great, right?

A far cry from proprietary PBX systems perhaps, but Asterisk has a vibrant ecosystem and is replacing systems from more established telephony vendors. Following interviews with the leaders of the Horde and Free Telephony projects, the Open Source Identity series talked to Asterisk founder and Digium CTO Mark Spencer about how one application can have such a profound effect on businesses and how open source can be a tough competitive landscape.

Efficiency key to Avaya's success, Giancarlo says

Charles Giancarlo spent more than a decade at Cisco Systems and was widely considered a likely heir to Chairman and CEO John Chambers before he left last year for investment company Silver Lake Partners. Then Silver Lake orchestrated a private-equity buyout of Cisco rival Avaya, and Giancarlo stepped in as interim president and CEO. In January, former JDS Uniphase chief Kevin Kennedy will take over day-to-day operations as president and CEO, and Giancarlo will become chairman. Stephen Lawson of the IDG News Service spoke with Giancarlo on Tuesday after he delivered the opening keynote at VoiceCon in San Francisco.
