# Asterisk Project : Asterisk Architecture

Added by malcolmd , edited by mdavenport on Sep 23, 2010

From an architectural standpoint, Asterisk is made up of many different modules. This modularity gives you an almost unlimited amount of flexibility in the design of an Asterisk-based system. As an Asterisk administrator, you have the choice on which modules to load. Each module that you loads provides different capabilities to the system. For example, one module might allow your Asterisk system to communicate with analog phone lines, while another might add call reporting capabilities. In this section, we'll discuss the various types of modules and the capabilities they provide.
