Source note · CUCM to Teams Phone migration
Direct Routing requires the user to be homed online, which is checked by confirming RegistrarPool has a value in the infra.lync.com domain; where OnPremLineUri is populated the number was assigned on-premises and must be cleared with Set-CsUser -LineUri $null in the Skype for Business Management Shell and synchronised before the number is configured online.
