Dedicated Instance Service Activation

Dedicated Instance is an optional add-on to Webex Calling that you must purchase before proceeding with the activation.

You can activate Dedicated Instance as part of the First Time Setup Wizard (FTSW) or activation can be deferred and completed later from Control Hub.

When Dedicated Instance is purchased, either as part of the initial Webex Calling order or added to the subscription later, you will receive a welcome email to set up the services. When you click the link, it takes you to the First Time Setup Wizard, where you can select Set up Dedicated Instance to activate the service. You can also choose to skip this step and complete the activation later.

When you select to set up Dedicated Instance, there are three input values that must be provided. Dedicated Instance is deployed and activated for a selected geographic location, so you must specify the region(s). For each Dedicated Instance region, you also need to input the user and workspace device count. These parameters are used to size the Dedicated Instance upon activation. The sum of the users and workspace devices across the regions cannot exceed the corresponding license quantity on the Webex Calling subscription.




After a Dedicated Instance has been activated in a given region, it cannot be undone.

If the Dedicated Instance setup was skipped during the First Time Setup Wizard, a notification is displayed in the Control Hub Overview page to Complete Service Setup.



After the Dedicated Instance setup as part of the FTSW has been completed, the Dedicate Instance(s) are activated for the specified region(s).

The Dedicated Instance service activation status can be viewed under services, Calling > Dedicated Instance tab.

As part of service activating, the following UC applications are deployed and sized accordingly:

  1. Cisco Unified Call Manager

  2. Cisco Unified Unity Connection

  3. Cisco Unified IM and Presence

  4. Cisco Expressway-Core and Edge

  5. Cisco Emergency Responder (only in AMER region)

In addition as part of activation, SIP connectivity is established between the Dedicated Instance and Webex Calling multi-tenant platform.

Dedicated Instance Service activation status

In Progress: The status In Progress means that your Dedicate Instance activation is in progress. The Estimated Completion provides the estimated time for completion of the Dedicate Instance service activation.



Upon successful completion of the Dedicate Instance service activation, you can start managing the UC applications under the Manage section.



Dial Plan Configuration

After a Dedicated Instance has been activated, basic dial plan elements for call routing will be configured in both the Webex Calling multi-tenant platform and each of the Dedicated Instances. If the customer requires call routing between the platforms they must incorporate these elements into the Webex Calling and the Dedicated Instance UCM dial plan accordingly.

Refer to Webex Calling Configuration Workflow for more information.

  • Configured Webex Calling Dial Plan Elements

    • Location

    • SIP Trunk

    • Route Group

  • Configured Dedicated Instance (Cisco Unified Communications Manager) Dial Plan Elements

    • SIP Trunk

    • Route Group

    • Route List


The pre-configured dial plan elements are prefixed with ‘WXC-DI’. For example, WXC-DI-<region>-<dial plan element>.


Customer administrator needs to configure the Main Number (E.164) for the location created in the multi-tenant, before any calls can be made.


Customer administrators are advised not to modify or delete any of the above pre-configured inter-operability dial plan elements otherwise it can cause call failures between the platforms.
