Subdued Off-Hook Voice Announce (SOHVA) Groups
The programmer can program the ability of station ports to originate and/or receive
SOHVA calls by assigning SOHVA calling groups to station ports. This means that he
or she can arrange certain station ports together for SOHVA calling between one another
while excluding other station ports in the system from this group.
The system provides eight different SOHVA groups that are fixed into a variety of
SOHVA receive/originate configurations. A programmer can assign one SOHVA group
to each station port to allow or to deny SOHVA receive and/or originate capability to it.
By properly assigning SOHVA groups to station ports, the programmer can open or
block SOHVA paths between stations.
The system is defaulted with no SOHVA groups assigned. When a station port does not
have a SOHVA group assigned to it, it’s user can originate SOHVA calls to any station
port and receive SOHVA calls from any station port.
SOHVA groups are fixed by the system into the following configurations:
