Station-To-Station Messaging
If a station has a DSS/BLF appearance at another station, a callback message indication
can be left at that station with the DSS/BLF appearance. The user can dial a special code
to turn on the BLF light at the called station that is assigned to the calling station. This
light indicates that a callback is requested. The light is automatically turned off if a
successful callback is made.
If a station number is not programmed for a DSS/BLF appearance at another station,
attempting to place a call back message will cause the central message desk station to
ring. If there is no central message desk assigned, no action will occur.

Subdued Off-Hook Voice Announce
With the subdued off-hook voice announce (SOHVA) feature, a user can make a voice
announcement from one station to another station that is off-hook and busy on a call. A
station being operated in a handsfree mode cannot receive a SOHVA. With SOHVA, the
caller delivers the call and the user receiving the call responds to it in a secure manner
that prevents the distant party from hearing either the announcement or the response.
The system precedes the announcement with a tone alert that it delivers to the handset
receiver of the called telephone. It also supplies a tone to the announcing caller to alert
them that they are making a SOHVA call. A programmer can set the quantity of tone
bursts from one to six. A user can respond to the SOHVA announcement either verbally
or non-verbally. He or she either effects a verbal response by pressing and holding the
MUTE button and speaking into the handset or effects a non-verbal response by pressing
a pre-programmed button to send a message to be shown on the display of the
announcing station (if it is an LCD speakerphone). The system automatically disconnects
the announcing station after it delivers the response message to it (and displayed if an
LCD speakerphone). Stations that have the voice announce blocking feature turned on
cannot receive a SOHVA. A programmer can use station class of service programming to
disable the SOHVA feature at a station port if desired.
Subdued Off-Hook Voice Announce Originate Button
This feature allows a telephone user to program a button at his or her station that she or
he must press before delivering a SOHVA call. This SOHVA enabled button allows a
caller, after hearing a busy signal, to decide whether to interrupt the called party in a
SOHVA manner. If the caller decides that the called should be interrupted, the caller can
press the button and complete the SOHVA call. This button, along with SOHVA groups,
allows system users greater control of the callers that are allowed to make SOHVA calls
and of the situations in which they are allowed to make them.
