Supervisor Tools: Listen-In, Whisper, Barge

The three classic tools

Silent monitoring. The supervisor hears both sides; neither the agent nor the caller hears the supervisor. Used for QA, training new agents, and reviewing performance.

Whisper Coach the agent in real time. The agent hears the supervisor (in their ear, like a coach on the sideline); the caller does not. Used during difficult calls to suggest next steps, offers, or de-escalation language.

Barge The supervisor joins as a three-way conference. Used when the call needs the supervisor to take over - escalations, refunds beyond agent authority, complex compliance scenarios.

Sentiment-driven supervisor alerts (AI Edition)

The wallboard shows every active call with a live sentiment colour. When a call’s sentiment drops below threshold for a configurable duration, the supervisor gets a prompt: “Call X is trending negative - listen in?”. One click and they’re in. Whisper or barge from the same interface.

This is the practical bridge from “we record everything and review after” to “we catch the escalation in real time and save the customer”. Most contact centres see measurable CSAT lift within the first quarter.

Permissions

• Supervisors only see queues they’re assigned to.
• Audit log records every listen-in, whisper and barge action.
• Role-based permission controls (some supervisors can listen but not barge, for example).
