This feature allows a telephone user to program a
button at their station that must be pressed to enable
the delivery of a SOHVA call. This SOHVA enabled
button allows the caller, after hearing a busy signal, to
decide whether the called party should be interrupted
in a SOHVA manner. If they should, the button can be
pressed and a SOHVA call completed. This button,
along with SOHVA groups allows system users greater
control of the callers that are allowed to make a
SOHVA call and of the situations that SOHVA calls are
allowed. Refer to the discussions titled: Secure
Off-Hook Voice Announce, and Secure Off-Hook Voice

ports can be arranged together for SOHVA calling
between one another while other station ports in the
system are excluded from this group.
Eight different SOHVA groups are provided by the
system. They are fixed into a variety of SOHVA
receive/originate configurations. One SOHVA group
can be assigned to each station port to allow or to
