What is Call Whisper?
Call Whisper is an IVR-based incoming call notification feature that plays a brief, private audio prompt to agents before they connect with a caller, identifying the call’s source, region, or purpose.
Instead of answering blind, your teams know who the call is for, where it’s coming from, or which number was used, before they say hello.
Designed for businesses handling high call volumes, various sub-factions, multiple regions, or complex IVR flows, Call Whisper brings context directly into every live conversation.
How Does Call Whisper with Global Call Forwarding Work?
Call Whisper operates inside your IVR configuration. Managers can upload or record these introduction prompts as required.
Once enabled, the feature plays the short, customizable audio prompt to the receiving agent after the IVR completes routing but before the caller is connected. The caller never hears the prompt, only your team does.

For example:
- “Call for France sales line”
- “Call from healthcare IVR”
- “Call from PPC campaign number”
- “Priority support customer”
This matters for global and multi-department businesses because
IVRs often route calls based on:
- Geography
- Language selection
- Product or service type
- Sub-businesses
- Campaign or number dialed
Call Whisper ensures that IVR routing strategies don’t end at delivery and continues into the agent experience, so responses are faster, more accurate, and more professional.
Benefits of Call Whisper
By revealing who the call is for and where it’s coming from, Call Whisper removes guesswork and helps teams deliver more prepared, professional responses. Here’s how your teams can benefit from this feature:
1. Instant Call Context
Agents know the source or intent of a call before answering. No guessing, no scrambling, or additional time taken.
2. Faster, More Confident Responses
Prepared agents reduce hesitation, awkward openings, and unnecessary transfers. They get right to the reason for the call.
3. Improved Routing Accuracy
Confirms IVR routing decisions at the agent level, reducing misrouted or mishandled calls.
4. Stronger Global Call Handling
Regional prompts (“Call from Germany,” “APAC support queue”) help teams adapt tone, language, and expectations immediately.
5. Better Performance in High-Volume Environments
Call centers and shared queues gain clarity even when handling multiple numbers, IVRs, or clients.
6. Private and Non-Disruptive
Prompts are heard only by the agent and never delay or affect the caller experience.
How Teams Can Use Call Whisper

Customer Support & Contact Centers: Know if a call is billing, technical support, priority customers, or language-specific before answering.
Marketing & Campaign Tracking: Assign and track different phone numbers or IVR paths to campaigns and whisper prompts like “Trade show lead” or “Google Ads call.”
