• Confirm that all details on the LOA for Link1 exactly match your Customer Service Record (CSR) with the current carrier. Any mismatch could result in the port being flagged as occupied.
• If you confirm that the details are incorrect, contact your carrier for clarification and request an updated LOA. They may need to make changes in their system to resolve the issue.
• Generate a new LOA using the Azure portal or PowerShell, ensuring that the customer's name and other required details are entered accurately. For guidance, refer to the below official documentation on LOA generation.
