"Never in the history of telecommunications has a phone system so suited to the needs of business been avail-able, at any price."
What is Asterisk?
Asterisk is a complete Business Phone System PBX without the proprietary hardware. The system runs on a traditional PC using the open source Linux operating system. The system provides all of the features you would expect from a PBX and many more. It even does voice over IP (VoIP) in many protocols, and can operate with almost all standards-based telephony equipment using inexpensive hardware.
The telecommunications industry spans over 100 years, and Asterisk integrates most — if not all — of the major technologies it has made use of over the last century. Just about anything you've ever heard about what an expensive PBX business phone system can do, Asterisk can do it: Auto-Attendant, Call Queueing, IVR, Digital Receptionist, Voice Mail, Email, Faxing, Conferencing, Call Transfer, Call Parking, Wake-Up Calls, Outbound Telemarketing, Music On Hold, Call Routing, Pager Notification,and much more. Plus, it can do all of these things usingvirtually any carrier - PSTN or VoIP.
While VoIP is often thought of as little more than a method of obtaining free long-distance calling, the real value of VoIP is that it allows voice to become nothing more than another application in the data network. Asterisk sits on the data network and harnesses VoIP technology to bring powerful applications to your business.
• Asterisk turns an inexpensive PC server running Linux into a reliable, sophisticated, robust, full-featured PBX telephone system
• Asterisk integrates seamlessly with your existing IT infrastructure because your telephony is all digital. One network for both voice and data.
• Asterisk provides all the functionality of a traditional PBX, but it also provides new features and capabilities a traditional PBX can’t offer.
• Because Asterisk is open source, you can change it and tune it as you need — unlike traditional systems that only provide closed boxes and closed interfaces. Never again will you be locked into proprietary obsolete equipment from a single-source vendor.
• Using Asterisk, we can quickly build a phone system for any enterprise, no matter how large or small. This is because the system scales from one user to literally thousands on hundreds of interconnected systems.
What you choose to implement is up to you. This system imposes no limits.
