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. Click the link to Create a Cisco Webex Order for a Customer. After the order is created, you can navigate to the First Time Setup Wizard, and 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.




Once the Dedicated Instance has been activated in a given region, it cannot be undone or changed to a different region.


The SIP URI address value provided by the customer will be the domain used for all the UC applications and Mobile and Remote Access (MRA) in the specified region(s).


You can only either choose EMEA or EU region for a customer organisation.

The Dedicated Instance UC application access details along with the credentials, will be shared only through the Webex App message to the partner or customer email ID provided in the Cisco Webex Order for a Customer wizard. By default, the access document is shared only to the partner's email ID through Webex App, if the partner's email ID is not available then the customer's email ID will be used for the Webex App message notification.

See, Webex App | Sign In for the First Time for more information.

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).

Dedicated Instance Service Activation Status

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

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.



Upon successful completion of the Dedicate Instance service activation, the activated services appear under Usage by region.

Dial Plan Configuration

After a Dedicated Instance is activated, basic dial plan elements for call routing is configured in both the Webex Calling multi-tenant platform and each of the Dedicated Instances. If you require call routing between the platforms, you must incorporate these elements into the Webex Calling and the Dedicated Instance UCM dial plan accordingly.

  • 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 in multi-tenant platform are prefixed with ‘WXC-DI’. For example, WXC-DI-<region>-<dial plan element>.

The pre-configured dial plan elements in Cisco Unified Communications Manager are prefixed with ‘xWxC’. For example, xWxC-<region>-<dial plan element>.

Refer to Dedicated Instance for Webex Calling - Base Configuration for more information on the pre-configured components.


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


You 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.
