SYSTEM OPERATION

As shown below, a direct call or a forwarded call from a station/trunk/Attendant terminates to the VMS
station in UCD group or Hunting group.
When the call is terminated to the VMS, the MP or the AP00 sends a call connection status information to
the VMS through the MCI. If the ANI information is sent from the network, the ANI information can be
added to the call connection status information by the system data programming (this feature is not avail-
able when the call is received from the CCIS trunk to the VMS). When the station/trunk/Attendant leaves
a message in the VMS, the VMS sends a Message Waiting lamp ON data for the appropriate station
through the PBX. After the station retrieves the messages, the VMS sends a Message Waiting lamp OFF
data for the appropriate station through the PBX.
