When you first configure TIM Professional, your extensions are automatically harvested from the data received from the phone system into a folder named New extensions. 

Extensions are individually named, and can be organised into Extension Groups for the purposes of reporting and administration. This administration is done using the Extensions screen, accessible by clicking on the button, as shown below:

If a call is made or received on an extension that the call logger didn't previously know about, it will automatically be placed in the New Extensions folder. The properties of each extension can be edited afterwards and, subsequently organised into new groups, if preferred.

 

 

<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 <img class="icon" src="http://www.tri-line.com/common/img/documentation/tim_professional/extensions_button.png" /> 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 <span class="reference">New Extensions</span>. You can then move these newly-discovered extensions
into groups you've already set up, or into new groups which you can
create.</p>
