To add a new trunk group to the system, click on the button at the bottom-right corner of the panel. A new window will appear, allowing you to enter a name for the new group. Click to save the changes.

To add more groups, follow the same procedure. The new groups will be displayed in the Trunk Groups panel, as shown below:

To apply any changes, click on the Save changes button at the top-right corner of the screen and enter the date range over which calls should be updated to reflect your new trunk configuration.

The time to complete the operation will vary, depending on the number of calls you are updating.

When the update process has been completed, the following notification will be displayed:

<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>
