Earlier this year, Microsoft published message center alert MC487014 (only sent to select tenants) concerning the discontinuation of Reverse Number Lookup for accounts with extensions that match the trailing digits of their phone number.
If you are impacted by this change but would like to continue using extension dialling, you will be required to configure tenant dial plans that normalise extensions into full numbers. You will also be required to remove the extension from the user account so they remain routable via Direct Routing.
Please note that the scheduled time for this change is an estimate. Microsoft advise that the change will be rolled out from end of February and completed by mid-March 2023. Should you require any assistance, please contact us at support@loopup.com
