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

+ Enable internal timing if Zaptel timing is available.
