When you migrate remote call control to a Lync Server 2010 deployment, you must remove legacy authorized host entries (known as a trusted application entries in Lync Server 2010) for any SIP/CSTA gateways in your legacy deployment. You must use the administrative tools included with either Office Communications Server 2007 R2 or Office Communications Server 2007 to remove authorized host entries from those deployments, respectively.

For details about how to remove an authorized host entry in Office Communications Server 2007 R2, see Remove an Authorized Host Entry in the Migration documentation.

For details about how to remove an authorized host entry in Office Communications Server 2007, see Remove an Authorized Host Entry (Communications Server 2007) in the Migration documentation.
