Phone Lock
Phone lock is used to lock the IP phone to prevent it from unauthorized use. Once the IP phone
is locked, a user must enter the password to unlock it. IP phones offer three types of phone
lock: Menu Key, Function Keys and All Keys. The IP phone will not be locked immediately after
the phone lock type is configured. One of the following steps is also needed:
- Long press the pound key when the IP phone is idle.
- Press the phone lock key (if configured) when the IP phone is idle.
In addition to the above steps, you can configure the IP phone to automatically lock the phone
after a period of time.
