Advisory tones

What are advisory tones?

Advisory tones are acoustic signals or tones that are played during a telephone call or call processing to inform the caller or agent of a certain status or action.

Where are advisory tones used?

Typical areas of application for advisory tones include

• Queue notifications: Tones or voice prompts that tell callers that they are on hold.

• Recording alerts: A tone indicating that the call is being recorded (e.g. to comply with data protection regulations).

• Call forwarding: A tone informs the caller that the call is being forwarded.

• System messages: Beeps in automated systems (e.g. IVR) that confirm certain actions or inputs.

Advisory tones improve the transparency and user experience in telephone systems by providing clear acoustic feedback and making the call process easier to understand for everyone involved.
