Voicemail detection
Voicemail detection, also called answering machine detection (AMD), is a feature of outbound calling systems that works out whether a call was answered by a person or by a voicemail greeting.
Explained
Voicemail detection, explained
When an automated system places a call, the first seconds tell it what picked up. A person usually says a short greeting and waits. A voicemail greeting is longer and ends with a beep. Detection uses those differences to decide how to continue.
Once it knows, the system follows a policy. It can hang up and try later, or wait for the beep and leave a short message. Detection is not perfect; very short personal greetings and noisy lines can be misread, so a sensible retry policy matters.
Voicemail detection matters most for callbacks and outbound campaigns, where many calls reach voicemail and leaving the wrong message wastes the contact.

Voicemail detection and Voxipo
Voxipo detects voicemail on outbound calls, such as missed-call callbacks and voice campaigns, and follows the voicemail policy you choose for the agent, either hanging up or leaving a message. Campaigns also support retries and calling-hour limits.
Questions
Voicemail detection: FAQs
Can Voxipo leave a voicemail when nobody answers a callback?
Yes, if you set the agent's voicemail policy to leave a message. You can also choose to hang up instead.
Is voicemail detection always accurate?
No system is perfect. Short personal greetings can be misread, which is why retry settings matter for campaigns.
Is voicemail detection used on inbound calls?
No. It applies to outbound calls, where the system needs to know whether a person or a greeting answered before it speaks.
