FEATURES AND SERVICES
Speaker
Description
Some 7300H-series voice terminals have a built-in loudspeaker that allows on-hook dialing,
group listening, and monitoring of call progress signals. The terminal user turns on the
speaker by pressing the SPEAKER button.
Pressing the button at an idle terminal has the
same effect as lifting the handset: the user is connected to the selected line and hears Dial
Tone. An associated LED is lighted when the Speaker is on. Speaker volume may be
adjusted by the terminal’s volume control located on the left side of the set.
The speaker and associated LED are turned off by pressing SPEAKER again or by lifting the
handset. The latter operation connects the handset to the associated voice channel. When
using the handset, pressing SPEAKER will turn on the speaker to support the Group Listen
feature; pressing SPEAKER again will turn off the speaker and associated LED. Note that
once the user has lifted the handset, it is possible to return to “hands-free” operation only
by putting the call on hold, hanging up the handset, then reconnecting the call by pressing
SPEAKER. Hanging up the handset will terminate the call whether the speaker is on or off.
Note:
The built-in speaker provides one-way communication (listen only). The user
must pick up the handset to converse.
Considerations
The built-in speaker supports group listening, monitoring of calls (e.g., while waiting on hold),
and on-hook dialing.
Hardware Requirements
Only 7300H-series (MERLIN) voice terminals with a SPEAKER button support this feature.
Sets with a SPEAKERPHONE button have full speakerphone service, which provides two-
way, on-hook calling.
