Call Whisper

Boost Agent Performance with Real-Time Call Whispering

Q: What is a call whisper message?

A call whisper message is an audio prompt played to the agent before answering a call. It provides context such as the campaign, caller source, or instructions, helping the agent handle the call more effectively.

Q: Why is it called whispering?

It’s called whispering because only the agent can hear the supervisor’s guidance—just like a whisper in real life. The customer remains unaware of the background coaching.

Q: What is call monitoring used for?

Call monitoring is used to evaluate calls for training, quality assurance, compliance, and customer service improvement. Unlike whispering, monitoring can be silent or involve barging into the call.

Guide agents during live calls without the customer ever knowing. Calilio’s call whisper feature is perfect for training new hires, correcting mistakes on the spot, and boosting agent confidence—all while keeping conversations professional.

What is Call Whispering?

Call whispering is a telephony feature that allows supervisors to speak directly to agents during live calls without the customer hearing. It’s designed to provide real-time coaching, training, and support so agents can perform better while staying confident on the call.

How Does Call Whispering Work?

When an agent is on a live call, supervisors can activate Whisper Mode from the Calilio dashboard. It lets them speak directly to the agent while the customer remains completely unaware.

For example, if a new sales rep is unsure how to respond to a question, the supervisor can whisper the right response in real time. The agent hears the guidance instantly, continues the conversation confidently, and the customer enjoys an uninterrupted experience.
