Direct effects for Operations**
API Request Limit Change
The maximum page size limit for the Get-CsPhoneNumberAssignment cmdlet will be reduced to 1,000 numbers per query, leading to potential disruptions in automated scripts or applications that rely on retrieving more than 1,000 numbers at once.

Increased Error Rates
Requests exceeding the new limit will result in 'Bad request' errors, which can lead to increased support tickets and user frustration if not communicated properly beforehand.
- roles: Support Staff, End Users
- references: https://learn.microsoft.com/en-us/powershell/module/teams/get-csphonenumberassignment?view=teams-ps
Operational Disruption

Opportunities**
Optimized API Usage
With the new page size limit of 1,000 numbers per query, organizations can optimize their API usage by batching requests more efficiently. This will reduce the number of API calls required and improve the performance of number retrieval operations.
- next-steps: Analyze current API call patterns and adjust scripts or applications to batch requests in compliance with the new limit. Provide training to relevant staff on the updated usage.
- roles: IT Administrators, Developers, Operations Managers
- references: https://learn.microsoft.com/en-us/powershell/module/teams/get-csphonenumberassignment?view=teams-ps
Improved User Experience in Number Management
By adapting to the new limit, IT can ensure that users experience fewer errors related to 'Bad requests'. This will enhance the overall user experience when managing phone numbers in Teams, as users will be less likely to encounter issues when retrieving their assignments.
- next-steps: Communicate the changes to end-users and provide guidance on how to retrieve phone numbers effectively. Update any user-facing documentation to reflect the new limits and best practices.
- roles: End Users, Support Teams, Help Desk Staff
- references: https://learn.microsoft.com/en-us/powershell/module/teams/export-csacquiredphonenumber?view=teams-ps
Cost-Effective Resource Allocation
With a better understanding of the new API limits, organizations can allocate resources more effectively, reducing unnecessary API calls and potential licensing costs associated with over-usage of API resources.
- next-steps: Review current API usage metrics and identify areas where costs can be reduced. Implement monitoring tools to track API usage post-update.
