Political voice broadcasting sends a recorded message to a list of voters over the phone, usually in the days before an election. It’s cheap, it’s fast, and it reaches people who ignore email. It’s also one of the most heavily regulated things you can do with a dialer, and the rules changed in ways many campaigns still haven’t caught up with.
Here’s what the channel is actually good for, what the law requires, and how to run it without generating complaints that outlast the election.
What voice broadcasting does that other channels don’t
A voice broadcast reaches a voter in their own language, in a human voice, without asking them to click anything. For older voters and rural districts that’s often the only channel with real reach. Turnout reminders on election morning are the clearest example: a 20-second message that says where the polling place is and when it closes does a job no email does at 7am.
The four uses that reliably work:
- Get out the vote. Election day and the day before. Short, specific, includes the polling location.
- Event turnout. Town halls and rallies, called 24 to 48 hours ahead.
- Candidate introduction. A short message in the candidate’s own voice, early in the cycle, in the districts where name recognition is low.
- Volunteer and donor mobilisation. Calling your own supporter list, which is legally the easiest ground and usually the most productive.
Where it fails is persuasion. A recorded message does not change anyone’s mind about a candidate, and campaigns that spend their broadcast budget on persuasion messaging get poor returns. Use it to move people who already agree with you, and to tell them where and when.
The rules, and the one that changed
Political calling in the United States sits in an unusual position. Political messages are not telemarketing, so the national Do Not Call registry doesn’t apply to them, and calls to landlines have historically had considerable latitude.
Mobile phones are a different matter. An automated call or a prerecorded message to a mobile generally requires prior express consent, and being a political campaign does not remove that requirement. Given how few voters have landlines now, this is the rule that governs most of what you’re doing.
The change worth knowing: in February 2024 the FCC confirmed that AI-generated voices in calls count as artificial voices under the TCPA. If your message uses a cloned or synthetic voice, it carries the same restrictions as a prerecorded one, and a number of states have since added their own disclosure requirements on top. Our write-up on AI disclosure rules and what they change inside a dialer covers where that has landed.
Beyond the federal layer, states set their own rules, and several are stricter than the FCC. Some require live-operator introductions before a recorded political message, some ban political robocalls outright at certain hours, and several require specific identification language. Check the state you’re calling into, not the state you’re calling from.
Whatever the jurisdiction, four things belong in every political broadcast:
- Identify who is calling in the first sentence, using the committee or organisation name
- Include a working callback number, and answer it
- Honour opt-outs immediately and permanently, across every campaign you run
- Stay inside calling hours in the recipient’s time zone, and stop earlier than the law allows on election eve
This is not legal advice, and election law varies enough that a campaign of any size should have someone check the specific states on the list. The point is that the software has to be able to enforce these things, which many cheap broadcast services cannot.
Message design decides your complaint rate
Most of the difference between a broadcast that works and one that generates angry voicemails is in the first five seconds and the total length.
Say who you are immediately. A message that opens with atmosphere before identifying the caller reads as a scam, and the recipient hangs up during the part you paid for.
Keep it under 30 seconds. Turnout messages can be under 20. Every additional second past that loses listeners without adding information.
Use the candidate’s actual voice for candidate messages. Voters can tell, and a professionally read script performs worse than a slightly imperfect recording from the person whose name is on the ballot.
Give one instruction. Vote on Tuesday, or come to the town hall, or call this number. A message with three requests gets none of them done.
Record separate versions per language and per district where the polling location differs. Generic messages that tell voters to “find your polling place” are close to useless.
Timing, and the mistake nearly everyone makes
The single most common error is calling too much, too late. A voter who receives four calls from the same campaign in the final week remembers the annoyance, not the candidate.
A pattern that works for a competitive district:
- One introduction call early, six to eight weeks out, in low-name-recognition areas only.
- Event calls as needed, only to the geography that could plausibly attend.
- One turnout call the evening before, between 5pm and 8pm local time.
- One turnout call on election morning, after 8am, to voters who have not yet voted if you have that data.
That’s two turnout touches, not five. Cap the total contacts per voter across all channels, not per campaign, or your phone, text, and door programmes will each stay within their own limits while the voter receives eleven contacts.
What the dialer has to handle
Political broadcasting has requirements ordinary marketing campaigns don’t:
Burst capacity. Election morning is a few hours long. A system that takes nine hours to work through your list is worthless on the one day that matters. Capacity has to be sized for the peak, not the average.
Per-district message routing. One campaign, many recordings, selected by the voter’s precinct. Doing this by splitting into dozens of separate campaigns is how mistakes happen.
Answering machine handling. Roughly two thirds of calls reach voicemail. Leaving the message rather than hanging up is usually the right call for turnout, and that’s a setting, not a default.
Opt-out capture that persists. A press-9 removal has to write back to the master list, not just the running campaign.
Its own reporting. Campaign finance rules mean you’ll need to show what was spent and what was sent. Exportable logs matter more here than in commercial work.
ICTBroadcast handles all of the above, and because it’s licensed per installation rather than per agent or per call, a campaign that broadcasts to 200,000 voters in a morning pays for the telephony minutes and nothing else. It runs voice, SMS, and email from the same contact list, which matters when your turnout programme uses more than one channel. It’s Asterisk-based and self-hosted, so the voter file never leaves your infrastructure, which is worth something on its own for a campaign.
If you want the mechanics of building the campaign itself, the voice broadcast setup walkthrough covers it step by step, and the packages page has the licensing detail.
Measuring it honestly
Voice broadcasting is hard to attribute, and campaigns routinely overclaim. Three numbers that are actually measurable:
Answer rate. Live answers as a share of attempts. Below 20% on a voter file usually means the data is old.
Listen-through. How far into the message people stay. If most drop at eight seconds, the opening is wrong.
Press-through. If you offer a keypress to connect to a volunteer or hear more, that rate is the closest thing to a genuine engagement signal.
For turnout effect, the only credible method is holding out a randomly selected control group and comparing turnout afterwards against the voter file. It costs you a few thousand contacts and it’s the only way to know whether the programme did anything. Most campaigns skip it and then argue about the result for four years.
FAQ
Are political robocalls legal? To landlines, generally yes, with identification requirements and within calling hours. To mobiles, an automated or prerecorded call usually needs prior express consent. State rules add further restrictions and several are stricter than federal law.
Does the Do Not Call registry apply to political calls? The national registry does not cover political messages. That does not remove the mobile consent requirement, and it does not override state law or your own internal opt-out list.
Can I use an AI voice for the candidate? Treat it as an artificial voice under the TCPA, which the FCC confirmed in 2024, and expect disclosure requirements in a growing number of states. Cloning a real person’s voice raises separate legal issues entirely. Our advice is to record the candidate.
How many voters can I call on election morning? That depends on your carrier capacity and channel count rather than the software. Plan the peak backwards from your deadline: a list of 100,000 in three hours needs sustained throughput you should test in advance, not discover on the day.
Should I use voice broadcasting or SMS? Both, for different jobs. SMS is better for links and reminders people want to keep. Voice is better for older voters and for anything where tone matters. Run them from the same list so your contact caps apply across both.
What message length works best? Under 30 seconds, and under 20 for turnout. Identify the caller in the first sentence and give exactly one instruction.
