Lync Phone Edition devices can be locked for security purposes. If you enforce phone lock, the device running Lync Phone Edition locks after a period of time that you configure. When a phone is locked, a user can make calls but cannot access calendar and contact information, voice mail, or call logs or use search. To unlock the phone, the user enters a PIN.

To enforce phone lock, enable and configure it by using Lync Server Control Panel or Lync Server PowerShell cmdlets. You can enforce phone lock globally or only within the site for which it is configured.

To configure and enforce the phone lock

  1. From a user account that is assigned to the CsUserAdministrator role or the CsAdministrator role, log on to any computer in your internal deployment.

  2. Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server Administrative Tools.

  3. Click Clients, and then click Device Configuration.

  4. On the Device Configuration tab, in the list of device configurations, double-click the configuration for which you want to change the phone lock settings.

  5. In the Edit Device Configuration dialog box, verify that the Enforce device locking check box is selected.

  6. In Minimum PIN length, accept the default value for the minimum number of digits that the unlock PIN must contain or specify a new value. The range for the PIN length is four to 15 digits, and the default is six.

  7. In Phone lock time-out, accept the default value for the minimum length of time before the phone locks itself or specify a new value. The range for the timeout is 0 to 60 minutes, and the default is 10. Enter the value in the format HH:MM:SS.

  8. Click Commit.

Enforcing Phone Locking by Using Windows PowerShell Cmdlets

Phone locking can be enforced by using the Set-CsUCPhoneConfiguration cmdlet. This cmdlet can be run either from the Lync Server 2013 Management Shell or from a remote session of Windows PowerShell.
