Call whispering is a voice-over-internet-protocol (VoIP) feature that lets managers listen to an active call between an agent and a customer and talk to the agent simultaneously without the customer knowing. It benefits customer service teams by speeding up issue resolution, empowering new agents, and making coaching easier for managers. In this article, we’ll explore further what call whisper is, how it works, and which business phone systems have it.
How Call Whispering Works
The call whispering process can be summed up in these steps: Find the call you want to listen to, join the conversation as an admin or through key codes, and click the “Whisper” option to talk directly to the agent. Here’s a more detailed look at the process:
- A manager looks at the list of active phone calls and selects one they want to supervise.
- The manager uses a key code or password to access the live call. The agent may hear a special tone, indicating that someone is monitoring the call.
- The manager listens to the ongoing conversation and clicks the “Whisper” button to give tips to the agent.
- After coaching, the manager clicks the “Stop Whispering” option.
VoIP Features Similar to Call Whispering
Part of explaining call whisper is differentiating it from other business VoIP features with similar function and purpose. Call monitor, barge, and takeover are often confused with call whispering. Refer to the table below to familiarize yourself with each tool’s functions and best use cases.
In summary, call monitor is more limited than whisper, as it only allows listening in to conversations. Barge, on the other hand, lets managers be actively present in calls, essentially creating a three-way call, whereas, in whisper, the manager’s participation is more discreet.
Finally, takeover offers team leaders sole control of the conversation, enabling them to completely remove the agent from the call to address the customer directly. Familiarize yourself with the call whisper meaning and differences from other VoIP capabilities to maximize its use.
Advantages of Call Whispering
Whisper is a valuable tool for improving the overall efficiency of operations as it helps streamline call handling and accelerates customer service delivery. These are the specific ways it benefits businesses:
Gives New Agents a Confidence Boost
New company representatives still learning the ins and outs of the company’s products and services will benefit from a call whisper service facilitating timely advice from managers. Team leaders provide quick answers to customers’ questions, removing the need for agents to consult colleagues and put the caller on hold.
Aside from actual knowledge, new agents receive real-time coaching on handling pressure, while offering quick solutions to customer concerns. Ultimately, the advice from team leaders helps representatives become more confident as they get used to the job.

Dialpad AI Contact Center displays the “Whisper to Agent” button in an active call that managers are listening to. The platform’s built-in artificial intelligence (AI) tool offers real-time transcripts of the conversation, helping team leaders better understand the context of discussions.
Aside from whisper, the system has call monitor, barge, and takeover features. If you plan to use the provider’s business phone platform, read our comprehensive Dialpad review to better understand our rating and its features.
Facilitates Continuous Training for Long-time Agents
Long-time agents likewise benefit from managers using whisper, as the monitoring session encourages them to perform well. With a supervisor on the call, they’re compelled to apply best practices: comply with the spiels, be more attentive to the caller’s needs, and resolve concerns within the first call. While doing this, they get more communication tips and have someone point out mistakes that spoil the customer experience.
Helps Managers Support Struggling Agents
A classic call whisper example use case is coaching agents who take longer than usual to resolve a customer concern. Team leaders observe how representatives handle actual calls and offer feedback for improvement. As struggling agents overcome hurdles, the entire team becomes more productive, satisfying performance metrics and achieving collective goals.

GoTo Contact Center allows managers to view agents’ statuses and call duration, helping them know which ones may need assistance. Note that only admins have permission to use whisper and other monitoring tools. But, as an admin, you have the option to extend access to these features to any user or user group.

Disadvantages of Call Whispering
While a call whisper system offers many benefits for agents and managers alike, it also has drawbacks. It’s important to be aware of these disadvantages to better manage the use of the feature in your operations.
May Cause Distractions
Since whisper allows managers to speak discreetly while a conversation is ongoing, representatives may get distracted. They might not fully understand the context of the customer’s concern or the manager’s advice. As the agent isn’t fully present in the dialogue, customer service is affected. To minimize distractions during the call, provide succinct instructions to agents.
Delay Agent Response
Some new agents may depend on the manager’s advice to address customer concerns, delaying talking to the caller to listen intently to the instructions. This spoils the customer experience, especially when the person on the other end of the line prefers quick responses to urgent issues. To avoid overly dependent agents, offer sufficient training—targeting skill and knowledge gaps.
