You can control the dial plan for your Cisco Spark Calling deployment. You can customize extension lengths, routing prefixes, and dialing preferences (internal and external) to be compatible with the dialing habits of your users and requirements.
These settings are also available in the first-time setup wizard. As you change your dial plan, the example numbers in https://admin.ciscospark.com update to show these changes.
Before You Begin
If you want to decrease the extension length in your organization, make sure extensions aren't assigned to users and features. You can go to https://admin.ciscospark.com and check what extensions are used under . Also, you must temporarily remove the Cisco Spark Calling license assignment for your users.
|1 || From the customer view in https://admin.ciscospark.com, go to Services, and then choose .|
|2 || Configure your internal dialing preferences:|
- Routing Prefix—This setting only applies to multisite dialing. Until multiple locations and tiered dialing are supported, choose None for this setting. For a flat dial plan, you don't require a routing prefix.
- Extension Length—You can enter 3–10 digits and the default is 3. When you increase the length, you're prompted to enter a prefix for existing extensions. When you decrease the extension, your existing extension ranges are deleted and you have to enter a new extension range for the new length.
|Note || |
After you increase your extension length, existing speed dials to internal extensions are not automatically updated.
- Internal Extension Range—The maximum is 10000 extensions for each range.
|3 || Configure your external dialing preferences:|
- Outbound Dial Digit—The number that users must dial to reach an outside line. The default is 9, and the value can be None if you don't require this dialing habit.
- Dialing Preferences—Choose how PSTN dialing is handled (full phone number or simplified local dialing). If you choose simplified, you can add a prepended area code if you want the code included by default and don't require users to dial it. You can also remove the leading 1, if necessary.
