<p>Extensions are individually named, and can be organised into <span class="reference">
Extension Groups</span> for the purposes of reporting and administration. This
administration is done using the <span class="reference">Extensions</span> screen, accessible
by pressing the <span class="reference">Extension</span> button on the function button panel
on the main screen.</p>

<p>If a call is made or received on an extension that TIM didn't previously know about, it
automatically allocates it to a special group called New
Extensions.  You can then move these newly-discovered extensions
into groups you've already set up, or into new groups which you can
create.</p>
