Why can't I mute my Unify OpenScape WLAN Phone WL4?
If you cannot mute the handset or set the ring volume to “Silent” on your Unify Telephone, the handset is likely configured to restrict you from muting or setting the volume to silent. Contact your system administrator for support and ask them to turn off the Prevent silent parameter to remove these sound restrictions.
What to do if Unify Telephone is locked?
If you can't use your Unify Telephone handset and see a dialog window saying it's locked, the phone lock feature is activated. To unlock it, enter the required PIN code. If you've lost the PIN code, contact your system administrator for assistance.
