VOICE BROADCASTING
Send voice blasts based on what people do, not a schedule
Send pre-recorded voice messages to thousands of contacts in minutes. Every broadcast carries each contact’s history into the send, so who gets the message, when, and what happens after is driven by what they actually did, not a manually built list.

THE PROBLEM
A standalone voice broadcast goes out and the campaign stops there
When voice broadcasting runs in a separate tool, a contact who presses 1 or calls back has nowhere to go. The campaign doesn’t know they responded. Staff rebuild the list manually before the next send.
A contact presses 1 or calls back. Nothing triggers. That moment of interest sits in the platform until someone manually decides what to do with it.
A contact who already donated gets a fundraising voice message the next day. The campaign doesn't know they gave. That's not outreach. That's noise.
Manually filtering and re-uploading contact lists for every send adds 300+ hours on a 20K-contact campaign.
THE SOLUTION
Most tools send your broadcast. CallHub keeps the campaign moving after it.
The difference shows up in the results.
HOW IT WORKS
One coordinated flow vs. disconnected voice blasts
A contact who presses 1 gets routed into a live call queue automatically. One who doesn’t respond gets a follow-up text. Every outcome tags the contact record in real time so every channel that follows knows what the broadcast found out.

FAQs
What is voice broadcasting?
Voice broadcasting is an automated communication technology that delivers pre-recorded messages to thousands of contacts simultaneously. CallHub's voice broadcasting service enables political campaigns, nonprofits, advocacy groups, unions, and schools to reach large audiences instantly without requiring extensive staff or phone infrastructure. Unlike standalone tools, CallHub's voice broadcasting is part of a unified outreach flow. Responses trigger follow-up texts, calls, or emails automatically.
What is voice broadcasting software?
Voice broadcasting software is a cloud-based platform that automates mass calling, letting you deliver a voice message to thousands simultaneously. CallHub's platform includes text-to-speech, press-1 campaigns for live agent routing, answering machine detection, and dynamic caller ID to maximize your response rate. Every feature connects to the broader campaign. What contacts do after the broadcast determines what happens next.
How does voice broadcasting work?
Setting up a broadcast campaign in CallHub takes minutes. Upload your contact list, create your message using text-to-speech or an uploaded audio file, configure settings like press-1 transfers or dynamic caller ID, and launch. The platform automatically dials all numbers, plays your pre-recorded voice message when answered, and skips voicemails or drops a separate message. When a contact presses-1 or calls back, their record updates and the next step in the campaign triggers without any manual work.
Are voice broadcasts legal?
Voice broadcasts are legal when organizations comply with TCPA regulations. Key requirements include obtaining prior express written consent for marketing calls, honoring the Do Not Call Registry, respecting timezone restrictions (8 AM to 9 PM local), and displaying accurate, verified caller ID. CallHub's voice broadcasting service includes automatic DNC scrubbing, STIR/SHAKEN compliance, and built-in timezone enforcement so every campaign stays within the rules without manual compliance work.
What is an example of voice broadcasting?
Political campaigns use voice broadcasting to send GOTV reminders to 50,000 voters in minutes. Nonprofits send event reminders or collect RSVPs using press-1 setups. Unions use automated voice campaigns for strike mobilization alerts and contract ratification updates. Schools send emergency notifications through mass calling. In all cases, the most effective approach is to use voice broadcasting as one step in a connected sequence, not a one-time send in isolation.
