This document provides high level configuration details about the Dedicated Instance for Webex Calling System Configuration (Dedicated Instance) that is built for a customer which includes Unified Communications (UC) applications:

  • Cisco Unified Communication Manager (Unified CM)

  • Cisco Unified Instant Message and Presence (IM&P)

  • Cisco Unified Unity Connection (CUCxN) and

  • Cisco Emergency Responder (CER)

  • Edge components (Cisco Expressways)

Cisco Configured Components

Cisco configures multiple components in the Customer’s Dedicated Instance UC applications. For these components to be easily identifiable, Cisco inserts an x in the beginning of the name of the component. This x prefix alerts partners to a Cisco-configured name, that the partner or customer administrators should not modify or delete. This format is also used for Cisco’s Operational monitoring/readiness of the Dedicated Instance UC applications.

The Partner or Customer should not modify or delete any of the following:

  • Region entries which are associated with resources in the Datacenter (DC) i.e., Conference bridges, SIP trunks, etc.

  • Device pool entries which are associated with devices in the Cisco’s Datacenter.

  • Security configurations as required

    • Credential policy configuration

    • SIP security profile configuration

  • Cisco configured SIP Trunks for various services integration, i.e., RedSky, Inter-op trunk to Webex Calling Multi-tenant, etc.

  • Cisco configures two CDR destinations in Unified CM to monitor the application and provide analytics in Control Hub for administrators.

Unless the Dedicated Instance document explicitly mentions to change a customer specific configuration in the SIP trunks.

Control Hub – Webex Calling


Cisco Assigned Name



Services → Calling → Location

  • WXC-DI-<region>-LOC

Location is mandatory for activation of Interop SIP trunk between Webex Calling and Dedicated Instance.


The customer administrator must configure the Main Number for this default Location created. If this is not done, you will not be able to make or receive calls through the Route Group associated to this Location. See Configure PSTN Connection section in How to Activate Dedicated Instance for more information.

SIP Trunk

Services → Calling → Call Routing → Trunk

  • WXC-DI-<region>-TRK-<DC>

SIP trunk one to each Dedicated Instance datacenter within a region is configured for basic interop between Webex Calling and Dedicated Instance.


These are default trunks created by Cisco, should not be modified or deleted.

Route Group

Services → Calling → Call Routing → Route Group

  • WXC-DI-<region>-RG

Route Groups are configured with the Interop SIP trunks and administrator can easily configure or link their custom Dial Plan to the default Route Group.

Call Policy Rule

To enhance the security of the base Dedicated Instance platform, and to promote good security practice, Dedicated Instance Expressway E’s are preconfigured with a Call Policy to block all inbound B2B calls.

During configuration and testing of B2B services, this call policy should be updated in line with the customers requirement. This ensures that the B2B calls are destined for the correct destinations and/or come from valid sources.

Refer to About Call Policy for more information.

The Dedicated Instance UC application access details along with the credentials are 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 is used for the Webex App message notification.

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