Voicemail Detection

When no one answers, your message still gets delivered — automatically.

Overview

Not every call will be answered by a live person. Volume Reach automatically detects when a call has reached a voicemail box and, if you have a voicemail template configured, drops a pre-recorded message on your behalf. This means your outreach continues working even when contacts are unavailable, without any manual effort on your part.

How Voicemail Detection Works

When a call connects, Volume Reach listens to the audio at the start of the call to determine whether a live person answered or whether the call went to voicemail.

High-confidence detection happens quickly — typically within the first second or two. When the system is confident it has reached a voicemail, it acts immediately: it waits for the beep and then drops your recorded message.

Lower-confidence situations — for example, when it is briefly unclear whether a person or a machine answered — allow a short window for the conversation to begin. If a live person greets the agent, the AI conversation starts normally. If the audio confirms voicemail, the drop is triggered.

The outcome is recorded as Voicemail in your campaign dashboard.

Setting Up Voicemail Drop

To use voicemail drop, you need a voicemail template. Templates are managed in Dialers > Voicemail Templates.

Creating a Voicemail Template

Go to Dialers in the main navigation and select Voicemail Templates.
Click New Template.
Give the template a name (for example, "Solar Campaign VM" or "Follow-Up VM").
Record or upload your voicemail audio. Keep it short — 20 to 30 seconds is ideal.
Save the template.

Attaching a Template to a Campaign

When creating or editing a campaign, you will find a Voicemail Template setting in the dialer configuration. Select the template you want to use. When a call goes to voicemail during that campaign, this message will be dropped automatically.

If no template is selected, the agent will hang up when voicemail is detected without leaving a message.

Voicemail Drop Billing

Each voicemail drop counts as one Voicemail Drop credit. This is separate from connected minutes — dropping a voicemail does not count as AI Connected Minutes since no live conversation took place. See Usage Rates for current pricing per drop.

Tips & Best Practices

Keep voicemail messages short. Contacts decide quickly whether to listen or delete. A focused 20-second message is far more effective than a 60-second one. State who you are, why you are calling, and what they should do next.
Include a clear call to action. Tell the contact exactly what you want them to do — call back a specific number, visit a website, or expect a follow-up call from your team.
Use a consistent caller identity. The name and company mentioned in your voicemail should match what appears on your caller ID whenever possible. Mismatches reduce callback rates.
Create campaign-specific templates. A general voicemail message performs worse than one tailored to the specific campaign. Mention the relevant offer or context.
Test your template before launching. Record a test call to your own phone to hear exactly how the voicemail sounds before it reaches real contacts. Check for audio quality, pacing, and clarity.
Avoid scripting that sounds automated. Natural-sounding voicemails get more callbacks. Speak as if you are leaving the message for a single person, not a mass audience.
