Replay is a feature of TC Oversight Controls that can be used to enrich, transform, cache, and bifurcate various data streams. It can filter messages from the mail stream and bifurcate it into your archive and supervision system to enrich communications, collect analytics in real time, and perform data type extractions to feed into analytics platforms. Replay accepts data in all sorts of forms, from files, email, databases, and analytics/big data platforms, and sends them to destinations of your choice in its native format, enriched, merged, or transformed. Emails are sent to be data extracted for trend analytics, indexed, or content analyzed. Replay can manipulate emails in any way of your choosing, as message manipulation is fully configurable and flexible. This functionality can do anything from automatically adding users to the Cc line of an email, identifying groups or names, changing email headers, filtering attachments, adding or removing information, or any other type of manipulation named by the client.
