    2. 2. Asterisk has won lots of awards!
    3. 3. What is Asterisk?  The Asterisk project started in 1999 when Mark Spencer released the initial code under the GPL open source license. Since that time, it has been enhanced and tested by a global community of thousands. Today, Asterisk is maintained by the combined efforts of Digium and the Asterisk community.  Asterisk is a Computer Based Telephone System software. At it’s core, Asterisk is an open source software that transforms an ordinary computer into a communications server. Since Spencer released Asterisk to the world in 1999 as a phone operating system, it has been downloaded 500,000 times, and it continues to be downloaded 1,000 times per day.  Digium is the inventor, sponsor, and maintainer of Asterisk open source and UC phone systems for SMBs.
    4. 4. More information please… When PBXs were originally developed, wireline phone calls were the only type of electronic communication available. Today, the communications landscape has expanded to include email, instant messaging, video conferencing, desktop sharing, SMS and mobile telephony. Unified Communications is a catch-all term that describes the process of merging all of these technologies and integrating them with business processes. Unified Communications aims to increase efficiency while simplifying management.
    5. 5. The Case for Asterisk: You can use Asterisk to build communications applications, things like business phone systems (also known as PBXs), call distributors, VoIP gateways and conference. Asterisk includes both low and high-level components that significantly simplify the process of building these complex applications. Currently boasting over two million users, Asterisk supports a wide range of TDM protocols for the handling and transmission of voice over traditional telephony interfaces, featuring VoIP packet protocols such as SIP and IAX among others. It supports U.S. and European standard signalling types used in business phone systems, allowing it to bridge between next- generation voice-data integrated networks and existing infrastructure Thousands of companies in more that 170 countries rely on Digium phone systems, here are but few:

    9. 9. What type of Business can benefit from using Asterisk?  Commercial offices with between 2 and 2000+ extensions  Call centres, requiring call queuing (inbound and outbound) and call recording, IVR, ACD.

    10. 10. Sounds good, so what do I need to know to use Asterisk? Lets think of Asterisk like an engine / vehicle metaphor. Asterisk is an engine. It’s powerful. It’s flexible, it has ENORMOUS potential.  What you require is a skilled engineer who can take the engine and build it into a vehicle.  A custom vehicle built specifically for your business needs and requirements.  Asterisk requires some fairly advanced technical skills, including a good working knowledge of IP networking, Linux system administration, traditional telephony experience and script programming know-how. Even experienced programmers will need to overcome learning curves to create a working system.  Ports also available for OSX and Windows
