What does "Call Barge-In" allow supervisors to do?

"Call Barge-In" is a feature that enables supervisors to join calls that are already in progress. This capability is primarily designed for providing live support and training to agents while they are interacting with customers. By being able to listen in or participate in the conversation, supervisors can offer real-time assistance, guidance, or coaching, which can greatly enhance the agent's performance and improve the customer experience. This feature is extremely beneficial for training purposes, as it allows supervisors to provide corrective feedback during a call, helping agents learn and adapt their behavior on the spot.

In contrast, the other options focus on different functionalities that do not align with the interactive nature of "Call Barge-In." Recording calls, monitoring performance, and interrupting calls for feedback serve different purposes within call center operations, such as quality assurance or performance evaluations, but do not encapsulate the essence of live support that "Call Barge-In" provides.
