Release Operator Connect Numbers from Customer

The Release Operator Connect Numbers from Customer request releases Operator Connect numbers from the customer tenant. Number Release requests are sent to Operator Connect to validate the request. Numbers are released from both from Live Platform and Operator Connect.

■ Request Handling rules:
● Phone numbers must be currently assigned to the specified Microsoft tenant
● Released numbers become available for assignment to other tenants
● The operation is processed asynchronously to handle large ranges efficiently
● Rate limiting applies to prevent system overload (10 requests per 10 seconds)
● For Ranges:
◆ All SBCs (Session Border Controllers) associated with the tenant must be online before processing
◆ The operation is processed asynchronously to handle large ranges efficiently
◆ Range expansion is performed server-side to generate individual phone numbers
■ Number Validation rules:
● Microsoft tenant ID must be a valid GUID format
● Phone numbers must be in E.164 format (see below)
● Maximum number of phone numbers per request is configurable (default limit applies)
● Phone numbers cannot be currently processing in another operation
● Request body cannot be empty or null
● For Ranges:
◆ Range start number must be less than or equal to range end number
◆ Range must be able to generate at least one valid phone number
◆ All associated SBCs must be online and accessible
● When deleting using the REST API, only numbers belonging to the same Tenant Id can be deleted in the same action; numbers cannot be deleted per service.
● Assigned numbers must be unassigned before they can be released (see Unassign Numbers).
