Asterisk Overview: An Open Source VoIP Application
Asterisk is an open source application on telephony applications and a full-featured call-processing server. It’s is one of the last technology that has been in existence too long that the open source group has touched on.
There has been and open source web server (Apache), mail server (qmail, sendmail, postfix etc), proxy server (squid), CMS (joomla, wordpress), streaming media (icecast) but never, until now, has anyone every tried offering voice application to the open.
Good thing about Asterisk is that it can be used as a stand alone, Asterisk-Only system, or it can integrate with an existing PBX system.
