[FAQ] How can I lock my phone?

The UCS 3.3.0 Software Version introduced the functionality to lock the Phone.


NOTE: All configuration changes need to be loaded from a provisioning server or imported via the Web Interface if supported (UCS > 4.x.x)


This is not the Skype for Business Lock functionality described => here <= 


OPTION 1 (via the Web Interface UCS 4.0.0 or later only):






A simple example configuration looks like this:


<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<!-- Phone Lock Example -->
<polycomConfig xmlns:xsi="" xsi:noNamespaceSchemaLocation="polycomConfig.xsd">
<feature feature.enhancedFeatureKeys.enabled="1"/>
    <lock phoneLock.enabled="1"/>


The basic feature needs to be enabled via the enhancedFeatureKeys and then activated via the phoneLock.enabled.


Lock your phone to do the following:


  • Prevent unauthorized outgoing calls.

  • Allow only authorized people to answer calls.

  • Prevent people from viewing or modifying phone displays or information (for example, menus, directory lists, call records, and speed dial keys).


Phone locked:




When your phone is locked:


  • You can only make an outgoing call to a number from a list of authorized numbers.

  • You have to enter a password to answer incoming calls. (Changed new feature no longer requires this was added in UC Software 5.4.4)

  • All keys and soft keys are disabled, except those keys that allow you to unlock the phone, make an authorized call, redial a number, or view the browser (if enabled).


The Phone can be unlocked using the standard user password of 123 or the administrator password of 456.


You change the User Password via the Phone (please see the attached phone_lock_feature document) or you can use:


<device device.set="1">
    <device.auth device.auth.localUserPassword="12345678">
      <device.auth.localUserPassword device.auth.localUserPassword.set="1"></device.auth.localUserPassword>
