Phone Lock
You can lock the IP phone to prevent it from unauthorized use. Once the IP phone is locked, anyone must
enter the password to unlock it.
Yealink IP phones offer three types for phone lock:
Lock the Menu soft key: it prevents unauthorized users from accessing the menu, changing the
personal settings for your phone.
Lock the Function keys: it only allows unauthorized users to use the keypad for placing a call,
answering or rejecting an incoming call and ending a call.
Lock all keys: it only allows unauthorized users to use the keypad for dialing emergency number or
authorized numbers that set up by your administrator, answer or reject an incoming call and ending
a call. T48G/S IP phones only support All Keys type of phone lock.
You can set a waiting time to lock the phone automatically. If the waiting time is set to 0, the phone will
not be automatically locked. You need to lock the phone manually.
The Volume key, HEADSET key and Speakerphone key are always available when you lock the phone.
