To prevent conflicts that could arise if both Control Hub and your CCPP vendor attempt to manage the same numbers, Webex Calling restricts certain number operations when your organization's phone numbers are managed externally by a CCPP vendor in Control Hub.

An administrator can’t add, delete, activate, or modify numbers through Control Hub if the number is externally managed by a CCPP​. However, you can move mobile numbers between locations within the same country, regardless of the specific PSTN connection option configured for those locations.

Bulk management of numbers

Add numbers— While adding new PSTN numbers, if the selected location’s carrier has external number management enabled, the system displays a warning message that number management is disabled by the carrier. You see a similar message when you add a mobile number and the selected Mobile Network Operator (MNO) has external number management enabled.

Move numbers—You can move mobile numbers along with the Direct Inward Dialling (DID), Service, and Toll Free numbers between locations within the same country.

Mobile numbers can move to any location that supports the mobile carrier. This provides greater flexibility for managing your mobile number assignments.
