Creating a trunk group

<p>To add a trunk group just click on the <img class="icon" src="http://www.tri-line.com/common/img/documentation/tim_professional/add_button.png" /> button, beneath the <span class="reference">Trunk Groups</span> (left-hand side) window.</p>

<p>The following screen appears.  Type the name of your new trunk group in the text box and press <span class="button">OK</span></p>

<p>When you have finished the process, all your new trunk groups will appear on the left-hand
side under the heading <span class="reference">Trunk Groups</span> as shown below:</p>

<p>Always remember to press the <img class="icon" src="http://www.tri-line.com/common/img/documentation/tim_professional/save_changes_button.png" /> button in order for your changes to take effect. 
When the configuration has been saved, the changes take effect
immediately.</p>

<p>However, calls made prior to your changes will not
necessarily reflect them, and so the system asks you what you want to
do about these old calls, in the following prompt:</p>

<p>If you want to backdate the changes to a specific date, enter the date range over which calls
should be updated to reflect your new extension configuration and
press <span class="button">OK</span>.</p>

<p>If you just want all calls to reflect the new set-up, click on the <span class="button">All Calls</span> button.</p>

<p>To leave old calls as they are, without updating them, click on the <span class="button">Cancel</span> button.</p>

<p>Depending on the magnitude of changes and the number of old calls you've asked to be
updated, this may take some time.  A progress indicator is shown in
the status bar.  When the update has been completed you will receive
notification indicating whether the process was successful or not.</p>
