The Find And List Phones screen in Cisco Unified Communications Manager has been enhanced in the following ways:

• The following columns have been added:

  • Last Registered: Displays the timestamp when an Unregistered device was last registered. The timestamp is displayed in the format MM/DD/YYYY HH:MM and the time is displayed in the local time format.

  • Last Active: Displays the timestamp when a device was last actively involved in a call. The timestamp is displayed in the format MM/DD/YYYY HH:MM and the time is displayed in the local time format.

  • Unified CM: Displays the host name or the IP address of the server for both registered and unregistered devices.

  If this feature is disabled, the Last Registered and the Last Active columns display Not Applicable for unregistered phones and the Unified CM column is blank.
