	<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.

	</varlistentry>
	<varlistentry>
		<term>-c</term>
		<listitem>
			<para>
			Provide a control console on the calling terminal.
			Specifying this option implies <command>-f</command> and will cause

	</varlistentry>
	<varlistentry>
		<term>-d</term>
		<listitem>
			<para>
			Enable extra debugging statements.

		<listitem>
			<para>
			Remove resource limit on core size, thus forcing Asterisk to dump

		<listitem>
			<para>

		</listitem>
	</varlistentry>
	<varlistentry>
		<term>-v</term>
		<listitem>
			<para>
			Increase the level of verboseness on the console.  The more times
			<command>-v</command> is specified, the more verbose the output is.

			asterisk to no longer fork or detach from the controlling terminal.
			This option may also be used in conjunction with <command>-r</command>
			and <command>-R</command>.
			</para>
			<para>
			Note: This always sets the verbose level in the asterisk process,

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
