trunks that are selected for each Outside Line digit in your Internal Dialing plan.
Also choose a trunk to use for emergency calls.
Note: This selection is relevant if you enabled multiple trunks. If you enabled only
FXO trunks, or only one SIP/BRI service, this page displays the trunk assignment
for the Outside Line digits.
• Outbound Trunk Assignment: Click the button to show or hide this section.
You can assign one or more trunks to each digit that is used to get an
outside line. You can assign different trunks to different digits. For example,
you may want your users to press 8 for an FXO trunk and 9 for a SIP/BRI
trunk.
• Emergency Calls: Click the button to show or hide this section. Choose a
trunk to use for emergency calls, such as 911 service, if supported by your
phone service provider. Contact your service provider for details. Also
obtain any information that users need to be aware of when placing
emergency calls through the trunk. For example, it may be necessary to
specify the site location when calling an emergency number.
Notes:
• Check the box to select a trunk. The order in which you check the boxes is
the order in which the trunks are used. For example if you select an FXO
trunk first and a SIP provider second, the SIP provider is used only when the
FXO trunk is busy.
