When migrating an on-premises-assigned Direct Routing number to Operator Connect (Set-CsUser -LineURI $null in Skype for Business Server), the number is out of service during the migration, so the cutover must be coordinated with the operator.

Checked 2026-10-02

The phone number will be out of service during the migration, so coordinate with your Operator Connect operator before you begin.
