Digital Phone
Group Listening
All Digital Phones have a built-in speaker. If enabled, the User may use the speaker to monitor
a call while using the Handset to converse with an Outside party. This enables a group of
people in the room to listen to both parties in the conversation.
CONDITIONS
- While using the Speakerphone, lifting the handset will turn-off the Speakerphone; to
activate Group Listening, the [SPEAKER] button must be pressed while the Handset is
Off-Hook.
- While in Group Listening Mode, pressing the [MUTE] button will cause the TX path from
the Handset to be Muted; the distant-end will still be heard over both the handset receiver
and the Station Speaker.
- If full Speakerphone operation is desired and available while in Group Listening Mode
simply replace the Handset to go On-Hook.
- Digital Phones without a built-in speaker (LIP8004D/LDP-7004/LDK-02N/etc.), are not
able to use this feature.
