Offhook Monitor

Description
Offhook Monitor lets you put a call on speaker while the handset is offhook. You can still
communicate with the other party via the handset, but you will also be able to hear the other party on
the phone's speaker. The other party can only hear what is transmitted through your handset however,
because audio is not transmitted through your microphone.
Operation
To put a call on speaker using the Offhook Monitor:
1. During a handset call, press the ON/OFF key.
2. To take a caller off speaker (disable Offhook Monitor) but
continue the call via the handset, press the ON/OFF key.
Considerations
• Offhook Monitor is available on VB-3411LDS, VB-D411LDS and VB-44225 key telephone
only.
• Offhook Monitor can be disabled system-wide.
