Off-Hook Voice Over (OHVO)
The OHVO feature enables users, off-hook on a call (CO or Intercom), to receive a voice
announcement through the handset receiver without interrupting the existing call. The
Voice Over is muted so it does not override or drown out the existing conversation. The
overridden party may then talk to the calling party using Camp On procedures, or use Silent
Text Messaging to respond to the calling party via LCD Displays.
Placing an Off-Hook Voice Over Call
When an OHVO station calls a busy OHVO station and a busy tone is received, the calling
OHVO station must press a preprogrammed OHVO button [628] to initiate an OHVO
announcement, and the following occurs:
The HOLD button LED flashes at the called OHVO station.
The OHVO receiving station receives a one-beep warning tone. The station receiving the
OHVO call must be off-hook and in H or P mode, then the calling OHVO party may begin
the voice announcement to the called OHVO party. The called OHVO station's existing
conversation is uninterrupted and the voice over announcement does not drown out the
existing conversation. If the receiving station is call forwarded, use 5# to override
forwarding.
The calling OHVO station is not connected or able to hear the called station's
conversation (the connection only allows the calling station to transmit to the called
station).
