Whisper tone
Many businesses use multiple phone numbers. A whisper tone tells you which number was called before you answer, so you’re immediately prepared.
This feature is especially useful if you forward calls or use numbers in different countries. The whisper tone lets you know exactly which number the caller dialed, helping you respond in the right context from the very first moment.
- Hear a beep or custom intro
