The ivr_supr process is invoked from the CUI menus on the Dialer to send commands to the ivr_conn process. When invoked, the ivr_supr process establishes a socket connection to a specific port being listened to by the ivr_conn process. Once established, it sends the specified command, disconnects and then terminates. The possible commands are CONNECT, DISCONNECT and GET_SCRIPTS (see The ivr_conn process).
