Control Hub – Internal Dialing Settings

You can customize extension lengths, routing prefixes, and dialing preferences (internal and external) to be compatible with the dialing habits of your users. The internal dialing settings help define your organization’s extensions and how your employees will make internal calls.

Notes:

• You can also configure the outbound calling permissions for each of your locations. For these steps, see this guide.
• Outbound dialing codes are not supported on Webex app or Cisco Room devices.

Configure Internal Dialing Settings for Your Organization

1. From Control Hub, select Calling from the left-hand navigation.
2. Select Service Settings.
3. In the Internal Dialing section, click Edit.

Note: A pop-up notice appears letting you know that provisioned phones will need to be restarted in order to apply any customizations. Select Continue to proceed.

4. Configure the following internal dialing settings:

• Location Routing Prefix Length—Choose the number of digits to be used to connect with users at other locations. We recommend this setting if you have multiple locations. You can enter a length of 2-7 digits. If you have multiple locations with the same extension, users must dial a prefix when calling between locations. For example, if you have multiple stores, all with the extension 1000, you can configure a routing prefix for each store. If one store has a prefix of 888, you'd dial 8881000 to reach that store.
• Steering Digit in Routing Prefix—Choose the number to set as the first digit of every routing prefix. You can set a value here regardless of whether you use location routing prefixes.

Note: User extensions should not start with the same number as a location’s steering digit.

• Internal Extension Length—Choose the number of digits for an internal call. You can enter 2-6 digits and the default is 2.

Note: After you increase your extension length, existing speed dials to internal extensions are not automatically updated.

5. Select Save to save your changes.

Specify Internal Dialing for a Specific Location

1. From Control Hub, select Calling from the left-hand navigation.
2. Select Locations.
3. Select the location you’d like to modify.
4. Under Call Settings select and configure Internal or External Dialing:

• Internal Dialing—Specify the routing prefix that users at other locations need to dial in order to contact someone at this location. The routing prefix of each location must be unique. We recommend that the prefix length matches the length set at the organization level. It must be between 2-7 digits long.
• External Dialing—You can choose an outbound dial digit that users must dial to reach an outside line. If you choose to use this feature, we recommend that you use a different number from your organization's steering digit.

Note: Users can include the outbound dial digit when making external calls to mimic how they dialed on legacy systems. However, all users can still make external calls without the outbound dial digit.
