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.
