For Direct Routing numbers assigned on-premises, the admin clears the number with the Skype for Business Server command Set-CsUser -LineURI $null, and the number is out of service during the migration, so it must be coordinated with the operator first.

Checked 2026-09-25

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