Off-Hook Voice Over (OHVO) 87
XTS-IP / XTSc-IP Station User Guide December 2005
To place 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],
-or-
Use the Soft Key’s OHVO option to initiate an OHVO
announcement. The following conditions will occur:
 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, in order to hear the calling OHVO party’s voice
announcement.
- The called OHVO station’s existing conversation is
uninterrupted and the voice over announcement does not
drown out the existing conversation. If 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 (connection only allows calling
station to transmit to the called station).
The calling station is placed in a one-time DND
mode upon initiating the Voice Over. One-Time
DND cannot be toggled during the OHVO call. The
station receiving the OHVO call must be off-hook
and in H mode.
