In this brief asterisk overview chapter will make sure you're familiar with the g_m_ asterisk and some of the non-technical foundational information related to each in this module entitled what is asterisk will describe n defined asterisk this will enable us to work through the rest of the course from a shared understanding of asterisks high-level capabilities and basic features in the next nigel will you be stingy on the asterisk company the remaining modules in this chapter will cover asterisks versioning model and several common asterisk use cases in the next chapter will dampen some of the more technical content.
First it's important that you have an understanding of some basic asker's concepts this will create a framework that will allow you to more easily understand the technical content perhaps the simplest yet most exact single sentence description of asterisk is that it is an open-source telephony platform it's open-source which means that the individual lines of code that define the program are freely available to anyone who wants them this means that developers from all over the world can and do you continually make improvements to the software in fact the g_m_ credits over a thousand individuals as contributors to the main pastors code base.
Because anyone can make modifications to the program new features can be added more rapidly then incomparable proprietary telephony platforms asterisk as a very low barrier to entry so almost anyone can start using it right away this means that there are thousands of people testing and reporting issues with asterisk there's a very large user base to help identify and correct problems estrous deals with to lengthen it's capable of interfacing with almost all popular traditional telephone technologies and systems as well as more modern technologies using did jim interface cards estrous can communicate directly with the analog phones and the public telephone network picket also connector all common for a or voice-over i key phones and systems a software add-on called skype for asterisk makes it possible to prison astra system to the millions of users on the skype network.
We describe asterisk as a platform because it's not confined to a single type of use edits a route asterisk switches telephone calls and can be used in any environment where that basic services needed we've seen asterisk use as a debugging or testing tool as a way to add was capability to an existing application and as a stable base on which new voice applications are built most of these east phone calls in one way or another but sometimes in non obvious ways asterisk is perhaps most commonly used as a full featured pbx buddy enjoys prodigies ability in a wide range of other two left me applications will look at a few specific use cases in an upcoming module.
We just described asterisk as and open-source telephony platform and look at each of those terms in some detail now would like to take a closer look at asterisk in some additional defining characteristics asterisk is feature full all of the features you'd expect from a world-class telephone system are supported caller i_d_ call recording conference calling and voice mail are just a few of the dozens of standard calling features asterisk natively supports asterisk is compatible it supports dozens of standards-based technologies for call control media transcoding and other telephony services there's a good chance that the communications technology that you want to use with asterisk is already possible today asterisk you scale opal it has been using applications ranging from an embedded device such as a home router all the way up to enterprise-class installations where dozens of interconnected astra systems process thousands of concurring calls in two thousand ten digimon else the astra skillful communications framework.
Which is a companion program that will make it even easier for estrous to excel in high performance endings links to the press release in a project page are included in the attachments have the attachments had is visible above the slide listings on the left hand side of this window next to the contents cap well use it throughout the course to share relevant files and links perhaps most importantly asterisk is free almost every feature astra supports is not only native we supported but is configurable at no cost adding voicemail capability or compensate your system isn't something you have to go and buy.
It simply something you configure asterisk include support for a few third-party technologies that do require api license to use but asterisk itself with all of its native features is free of charge finally asterisk is supportable though there's a learning curve when first getting started you're doing the right thing by going to this training we expect you'll find that asterisk as many details that must be learned before you can do much with it but eventually its behavior in configuration will almost become intuitive if you find that you enjoyed this course and seek a deeper level of asterisk knowledge we encourage you to attend one of our more in-depth instructor led classes to learn even more.
Did you know is also available to help you support your aster system we offer several levels of asterisks support subscriptions based on the number of systems you need covered and what kinds of support you want details about the each of these offerings are available in the attachments tab in the last slide we describe what asterisk is it's also help for the focus for a moment on what past risk is not though asterisk enjoys widespread popularity as a feature for pbx it's not the tricky solution that is pre configured out-of-the-box as delivered by digi m ash was chasm its flexibility including literally thousands of individual configurable options that can be set by the system administrator in addition the asterisk i'll put it work all running is handled is infinitely customizable so some amount of knowledge is necessary to be able to express to asterisk how you'd like it to behave but that doesn't mean that turnkey solutions based on asterisk and owning soonest if you interested and asterisk based pbx it significantly reduces the complexity configuring the features needed in a business phone system considered the g_m_'s award-winning switch box pbx switch box optimizes aster setup back reconfiguring hundreds of options that may keep easy deeper vision of phone system.
It also reduces complexity by eliminating the need to directly configure asterisk when using switch box all configuration options are made through the switch box web interface which is much more intuitive than the raw asterisk configuration of course using switch fax or any turnkey pastor solution trade some of pastors any flexibility for ease of use switch box sharon's and pbx and similar environments but it's not a perfect fit for all telephony applications to learn more about switch box you can click on the attachments have and follow link to the beach and website in this model.
I given you a brief overview of asterisk of course this entire courses about asterisk so will be giving much more information.
