ScreenshotNew SYSTM! – “What is Asterisk? Asterisk is an insanely powerful, yet easy to use, open source voip telephony toolkit (server software) that runs on virtually any platform. It allows anyone to manage VoIP services in their own home in more powerful ways than the most expensive PBX (public branch exchange). For example, it can serve as a gateway from a VoIP service to your copper phone lines, forward calls to your mobile device from wherever you are, allow you to create VoIP connections to anyone on the Internet, manage voicemail, prompts … a virtually limitless capability depending on how far you want to take it.” [via] Link.
