A proactive call services system serving as a new node or switching network within a closed subsystem is disclosed. Remote monitors provide information necessary to allow the provision of enhanced services to the closed subsystem, which may be a telephone operator position system (TOPS) switch of a public switched network (PSN). The proactive call services system includes a network interface, voice interface, call processing platform (CPP), link platform and monitors integrated with the PSN. The system gathers information as the TOPS switch processes a call, and with this information offers additional proactive call services to the caller.
