Whisper is a call center feature that allows a supervisor or manager to speak privately to a customer service representative during an ongoing call, without the customer hearing. The supervisor can provide guidance, advice, or information to the representative, helping them to handle the call more effectively.

Whisper is particularly useful for new or inexperienced representatives who may need guidance during a call, or for representatives who are handling complex or difficult customer interactions. By providing real-time feedback and coaching, the supervisor can help the representative to resolve the customer’s issue more quickly and effectively.
