Imagine an IP voice and unified communications system that can be integrated into any application and customised to meet business needs. Sounds great, right? Well that project is the Asterisk IP-PBX and it's free to use and you get the source code. 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 CEO Mark Spencer about how one application can have such a profound effect on businesses and how open source can be a tough competitive landscape.

To say Sabre Holdings is a believer in open source technology is an understatement. Its IT department supports the Travelocity Web site, the Sabre Travel Network and Sabre Airline Solutions, and the company has been using open source tools for some 10 years, according to CTO Robert Wiseman. Cost certainly factors into the reason, but it's Sabre's ability to control its own destiny by making whatever changes it deems necessary that's the real motivation. Along with Kevin Bomar, Sabre's senior principal of middleware services, Wiseman explains how open source software and the community that supports it help Sabre deliver solutions that meet its demanding uptime requirements.

Move over proprietary telephony systems. Australian engineer David Rowe started the Free Telephony Project three years ago to build an affordable IP-PABX system out of free hardware and software. That’s right, the design of the Free Telephony Project IP-PABX is open for any interested person to review and improve. With the first Free Telephony Project products now available and in use world-wide, Rowe hopes it will go along way to improving the availability of voice services in developing nations. In this edition of Open Source Identity, TechWorld interviews Rowe to uncover the burgeoning business of open product development.

Microsoft has been making moves on the licensing front and accommodations with open source, such as its controversial 2006 agreement with Novell pertaining to Suse Linux. Looking to elaborate on Microsoft's activities, Horacio Gutierrez, Microsoft vice president and deputy general counsel for Intellectual Property and Licensing, met last week with Paul Krill in San Francisco. Companies today, Gutierrez said, have become "mixed source" ventures rather than the world being divided up between open source and proprietary.

Solaris has been Sun Microsystems's bread-and-butter Unix system since 1992. While Unix platforms such as Solaris now are up against the open source Linux juggernaut, Sun maintains it has the technological advantages and accommodations for open source to keep Solaris in the game. The company also cites important customer wins as evidence of the platform's continued strength. To hash out the state of Solaris in today's marketplace, InfoWorld editor at large Paul Krill recently met with Jim McHugh, vice president of Solaris marketing at Sun, at the company's California campus.

We tend to think that everybody who's anybody in the tech world has a blog, right? Well, Linus Torvalds didn't have a blog, at least not until dipping his toe into the waters with this one -- "Linus' Blog" -- which launched last Thursday.

Google, which celebrates 10 years of its incorporation this month, remains strongly committed to its Enterprise unit and to the customers it serves, including IT and business managers and CIOs, although most of the company's revenue comes from online advertising.

Paul Cormier is Red Hat's executive VP and head of Red Hat products and technologies divisions. His experienced thumb is firmly planted in many Red Hat pies; including engineering, product management and product marketing. The company credits the introduction of Red Hat Enterprise Linux (RHEL) to Cormier's leadership and experience in enterprise technology. Cormier has returned Down Under on another visit to Red Hat's research and development team in Brisbane, and took some time out to chat with Computerworld about the anticipated boom in virtualisation, cloud computing, Microsoft's open source initiatives, CentOS, JBoss Application Server 5.0, how open source software can aid the current economic downturn, and of course, the growing role of Linux and RHEL in the enterprise.

While perhaps best known as a major social networking site in the Web 2.0 vein, Facebook is becoming a popular place to interface with potential customers, similar to what companies such as Scribe and iLike have done. Facebook also is being viewed as a place for enterprise collaboration, with Serena Software leveraging the site for this purpose. To get perspective on Facebook, InfoWorld Editor at Large Paul Krill recently spoke with Aditya Agarwal, Facebook director of engineering. Agarwal formerly worked in the Oracle server technologies division.

Open Source Law founder, Brendan Scott, discusses the legal implications of FOSS in Australian government and enterprise organisations.

The launch of Microsoft's new interoperability principles have been both cautiously welcomed and sceptically scrutinised as the company goes about convincing the IT industry that it is genuine in its pursuit to provide interoperability with rival products, more consumer choice, less vendor lock-in and greater collaboration with the open source community.
