<h3 id="Asterisk13Application_DISA-Synopsis">Synopsis</h3>

<p>Direct Inward System Access.</p>

<h3 id="Asterisk13Application_DISA-Description">Description</h3>

<p>The DISA, Direct Inward System Access, application allows someone from outside the telephone switch (PBX) to obtain an <strong>internal</strong> system dialtone and to place calls from it as if they were placing a call from within the switch. DISA plays a dialtone. The user enters their numeric passcode, followed by the pound sign <code>#</code>. If the passcode is correct, the user is then given system dialtone within <em>context</em> on which a call may be placed. If the user enters an invalid extension and extension <code>i</code> exists in the specified <em>context</em>, it will be used.</p>

<p>Be aware that using this may compromise the security of your PBX.</p>

<p>The arguments to this application (in <code>extensions.conf</code>) allow either specification of a single global <em>passcode</em> (that everyone uses), or individual passcodes contained in a file (<em>filename</em>).</p>

<p>The file that contains the passcodes (if used) allows a complete specification of all of the same arguments available on the command line, with the sole exception of the options. The file may contain blank lines, or comments starting with <code>#</code> or <code>;</code>.</p>

</div></div>

<h5 id="Asterisk13Application_DISA-Arguments">Arguments</h5>

<ul>
	<li><code>passcode|filename</code> - If you need to present a DISA dialtone without entering a password, simply set <em>passcode</em> to <code>no-password</code><br />
You may specified a <em>filename</em> instead of a <em>passcode</em>, this filename must contain individual passcodes</li>
	<li><code>context</code> - Specifies the dialplan context in which the user-entered extension will be matched. If no context is specified, the DISA application defaults to the <code>disa</code> context. Presumably a normal system will have a special context set up for DISA use with some or a lot of restrictions.</li>
	<li><code>cid</code> - Specifies a new (different) callerid to be used for this call.</li>
	<li><code>mailbox</code> - Will cause a stutter-dialtone (indication <strong>dialrecall</strong>) to be used, if the specified mailbox contains any new messages.
	<ul>
		<li><code>mailbox</code></li>
		<li><code>context</code></li>
	</ul>
	</li>
	<li><code>options</code>
	<ul>
		<li><code>n</code> - The DISA application will not answer initially.</li>
		<li><code>p</code> - The extension entered will be considered complete when a <code>#</code> is entered.</li>
	</ul>
	</li>
</ul>
