Control Hub can move numbers between locations only within the same country and from the same PSTN provider or Local Gateway, and a location's main number cannot be moved. in context
When adding numbers in Control Hub, turning on Activate Numbers Later makes them available for configuration immediately while leaving activation for later, which Cisco says to use when porting numbers later. in context
Control Hub deletes phone numbers in bulk only when they are unassigned; a number assigned to a user, workspace or feature cannot be deleted. in context
An inactive number assigned to a user, workspace or feature stays inactive until it is activated; Control Hub can activate numbers individually or 500 at a time in bulk. in context
A Webex Calling location must have a main number if it has any trunks or any extension-only users, workspaces, virtual lines or features. in context
Webex Calling Control Hub allows up to 1,000 numbers per add operation and activation of 500 numbers at a time. in context
When adding numbers in Webex Calling Control Hub, numbers must be in E.164 format for every country except the United States, where national format is also accepted. in context
In Webex Calling Control Hub, the Activate Numbers Later option makes added numbers available for configuration immediately while deferring activation, and is intended for numbers that will be ported later. in context
Webex Calling Control Hub can bulk-activate up to 500 numbers at a time. in context
In Webex Calling, an inactive number that is already assigned to a user, workspace or feature remains inactive until an administrator activates it. in context
Numbers that will be ported later are added with the Activate Numbers Later option, and an inactive number assigned to a user, workspace or feature stays inactive until it is activated. in context
Numbers are added in Control Hub under Services, PSTN and Routing, Numbers by choosing Manage then Add, up to 1000 numbers at a time, in E.164 format except in the United States where national format is accepted. in context
A phone number assigned to a user, workspace or feature cannot be deleted in Control Hub, and bulk deletion is restricted to unassigned numbers. in context
Control Hub can activate up to 500 inactive phone numbers at a time from Services > PSTN & Routing > Numbers. in context
In Control Hub under Services > PSTN & Routing > Numbers > Manage > Add, an administrator can enter up to 1,000 phone numbers at once, separated by commas. Each number is validated as it is entered. in context

Only unassigned phone numbers can be deleted in bulk in Control Hub. in context
The organization's phone numbers can be exported to a CSV file from Services > PSTN & Routing > Numbers > Manage > Export. in context
Bulk phone number deletions and moves between locations run as tasks in Control Hub Task Manager, and numbers that cannot be processed show as errors there. in context

Inactive non-mobile numbers are activated from the Actions menu or by bulk activation of up to 500 numbers at a time. in context
A number already assigned to a user, workspace or feature cannot be deleted in Control Hub; only unassigned numbers are eligible for deletion. in context
A number can be moved between locations only if both are in the same country and use the same PSTN provider or local gateway, the number is active and unassigned, and it is not the location's main number. in context
Numbers added in Control Hub must be in E.164 format for all countries, except that United States numbers may also use national format. in context
The 'Activate Numbers Later' option makes added numbers available for configuration immediately, but the admin must contact the carrier to activate them. The page recommends it when numbers will be ported later. in context
A number that shows as inactive in Control Hub is a likely cause of a Webex Calling number that rings nothing, but no current Cisco article seen states what an inbound caller experiences when the number is inactive. inferred in context
An inactive number stays inactive when it is assigned to a feature, user or workspace; assignment does not activate it. in context
Webex Go mobile numbers are onboarded as inactive and are activated when they are assigned to a user. in context
A number can be moved between locations only if both locations are in the same country and use the same PSTN provider or Local Gateway, and the number is active and not assigned. A location's main number cannot be moved. in context
The Activate Numbers Later option makes added numbers available immediately for configuration while they stay inactive until activated, which suits numbers still being ported. in context
Numbers are added from Services > PSTN & Routing > Numbers by choosing Manage > Add, selecting the location, entering comma-separated numbers and saving. in context

A phone number belonging to a block cannot be deleted in bulk unless every number in that block is unassigned, and a delete attempt on part of a range fails until the entire block is selected. in context
Control Hub activates a maximum of 500 phone numbers at a time in its bulk activation flow, while a single add operation accepts up to 1000 numbers. in context
