The Linux Telephony Kernel API
There are many open-source programs available now that use this API. However, the most well-known and widely used program is ohphone, a console application using the open-source OpenH323 library. Ohphone is part of the OpenH323 Project (www.openh323.org) and is in daily use by thousands of people to make free, high-quality phone calls over the Internet. Ohphone not only fully supports the Linux telephony API, but it is also compatible with other H.323-based products like Microsoft NetMeeting<+H>tm<+H> and Cisco voice-enabled routers. A more detailed discussion of this fine software is too much for this article, but you're encouraged to look at its web site to catch the latest news. The company that developed the OpenH323 library was recently acquired by Quicknet Technologies, Inc. as part of Quicknet's efforts to ensure continued major development effort of this open-source project. With such full commercial backing and a commitment to open source, I expect the OpenH323 Project software to become even better in the near future.
The Linux telephony API provides a common and consistent interface for developing telephony software on Linux. While there is currently only one vendor (Quicknet Technologies, Inc.) with fully compliant drivers for this API, several others are working toward compliant drivers. The API is lean, well designed, will not conflict with the existing API for sound cards and provides the ability to support multiple vendors behind the same interface. There's sure to be some exciting new telephony software developed for Linux in the coming year.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
