<p>As with extension numbers, TIM automatically picks up unallocated trunk numbers as soon
as they are used to make or receive a call. All newly-discovered
trunks are placed in a group called <span class="reference">New Trunks</span>, under the <img class="icon" src="http://www.tri-line.com/common/img/documentation/tim_professional/trunks_button.png" /> function button, as shown below:</p>

<p>You can also input trunks manually. We will show you how to do this further on in this
section.</p>

<p>You can set-up trunk groups and allocate trunks to these groups.</p>
