VHunter · Voicemail detection

Voicemail, detected in early media. Before it picks up.

VHunter analyzes the early media of every call and recognizes voicemail by its frequency signature, not by speech patterns. The call is cut before the voicemail picks up, and the contact continues on WhatsApp.

How it detects

Before the voicemail picks up. By frequency, not by patterns.

Pattern-based detection waits for the call to be answered so it can listen to the greeting. VHunter works earlier: it recognizes voicemail in the early media by its frequency signature and cuts the call in time.

In the early media

We analyze the audio that arrives before the answer, in real time and on our network.

Frequency, not patterns

We recognize voicemail by its frequency signature, not by what the greeting says.

Cut before the answer

The call is cut before the voicemail picks up.

High effectiveness rate

Detection designed for high-volume operations.

After detection

Every call where it belongs. People to agents, voicemail to another channel.

When a person answers, the call continues as usual. When it's voicemail, the call is cut and the contact continues on WhatsApp (or by SMS if you operate in Mexico).

A person answers

The call continues and is handled by your team or by an AI voice agent.

It's voicemail

Whoever couldn't answer gets a WhatsApp message to pick the conversation back up. In Mexico, by SMS too.

More time with people

Your agents, human or AI, spend their time on the calls a person answers.

Savings and effectiveness

Big savings on voicemail. And more conversations with people.

Cutting voicemail calls in time means big savings for your operation. And with a high effectiveness rate, your campaign puts its resources into the people who do answer.

Big savings on voicemail

Every voicemail detected is a call cut before the answer.

Frequently asked questions

What people ask us about VHunter

What is VHunter?

It's Astroline's voicemail detector. It runs on our network: it analyzes the early media of every outbound call and recognizes voicemail before the call is answered, so the call can be cut in time.

What is early media?

It's the audio that travels on a call before it's answered, such as the ringing tone or network announcements. VHunter analyzes it in real time to recognize whether the call is going to end up in voicemail.

How is it different from pattern-based detection?

Pattern-based detection waits for the answer and listens to the greeting (its silences, its length, its words) to decide whether it's a person or a voicemail. VHunter decides before the answer, using the frequency signature, so the call is cut before the voicemail picks up.

What happens if a person answers?

The call continues as usual and is handled by your team or by an AI voice agent, depending on how your campaign is set up.

How much does it save?

Cutting voicemail calls in time means big savings on voicemail and frees your team for the calls a person answers. The exact saving depends on the volume and profile of each campaign; we'll help you estimate it with your own data.

How reliable is the detection?

VHunter works with a high effectiveness rate. Because it relies on the frequency signature rather than the content of the greeting, it doesn't need to understand what the voicemail message says.

Does it work with my dialer?

Yes. VHunter runs on the Astroline network, so it works with any dialer or contact center platform that sends its calls through our SIP Trunk. There's nothing to install on your platform.

What do I do with the contacts that go to voicemail?

You can follow up on WhatsApp (or by SMS in Mexico, where we're an SMS provider) or try again later from your dialer. And if you'd like to automate it, an AI agent can pick the conversation back up on WhatsApp.

Less voicemail, more conversations. Turn on VHunter in your operation.

We support you through the whole process: SIP Trunk connection, go-live and follow-up on WhatsApp.
