  43         <title>DESCRIPTION</title>
  44         <para>
  45         <command>asterisk</command> is a full-featured telephony server which
  46         provides Private Branch eXchange (PBX), Interactive Voice Response (IVR),
  47         Automated Call Distribution (ACD), Voice over IP (VoIP) gatewaying,
  48         Conferencing, and a plethora of other telephony applications to a broad
  49         range of telephony devices including packet voice (SIP, IAX2, MGCP, Skinny,
  50         H.323) devices (both endpoints and proxies), as well as traditional TDM
  51         hardware including T1, E1, ISDN PRI, GR-303, RBS, Loopstart, Groundstart,
  52         ISDN BRI, and many more.
  53         </para>
  54         <para>
  55         At start, Asterisk reads the /etc/asterisk/asterisk.conf main configuration
  56         file and locates the rest of the configuration files from the configuration
  57         in that file. The -C option specifies an alternate main configuration file.
  58         Virtually all aspects of the operation of asterisk's configuration files
  59         can be found in the sample configuration files.  The format for those files
  60         is generally beyond the scope of this man page.
  61         </para>
  62         <para>
  63         When running with <command>-c</command>, <command>-r</command> or <command>-R</command>
  64         options, Asterisk supplies a powerful command line, including command
  65         completion, which may be used to monitors its status, perform a variety
  66         of administrative actions and even explore the applications that are
  67         currently loaded into the system.
