Call Whisper: tell whoever answers what the call is about
Play a short private message to the person who answers before the caller is connected — e.g. "This is a business call" — the caller hears nothing.
Which plans include it
Included on Growth and above. On Free Trial, Entry, Plus you can add it on its own at £2.50 a month from Features & add-ons.
What it means
Call whisper is an announcement only the answering person hears. It is ideal when calls are forwarded to mobiles, so you know to answer "Good morning, Acme" not "Hello?".
What it does
- Plays your message to whoever answers, on every incoming call.
- Connects the caller as soon as it finishes (plus any delay you set).
- Speaks your typed text, or plays an uploaded MP3/WAV.

Examples
Know before you answer
Callers to your sales number trigger the whisper "Sales enquiry" — you hear it before the caller is connected and answer with the right greeting.
Two businesses, one mobile
Whisper "Call for Bloom Florists" on one number and "Call for Bloom Events" on the other, so you always know which business the caller rang.
Recommended settings
- ★Keep it under 3 seconds — the caller is waiting.
- ★Use a different number per advert plus whisper so staff know where the lead came from.
Abbreviations on this page
- Whisper — Whisper / whisper coaching
- Speaking to your colleague during a live call without the caller hearing. Call Whisper (the menu item) is different: a short message played to whoever answers before the caller is connected.
- Example: A supervisor whispers "offer the discount" and only the agent hears it.
- TTS — Text to speech
- Typing words and having them spoken in a natural voice. The Greetings studio and Greeting Menus use it.
- Example: Type "We are closed for lunch" and TTS turns it into speech in the voice you choose.
