How bots find your AI receptionist's number
Your number is public on purpose
A business number exists to be found. It's on your website, your Google Business Profile, your ads, your social pages, every directory that has ever listed you. That's the point, and it's also why "how do I keep bots from finding it" is the wrong question. They already have it, or they'll get it the same way your customers do.
What changes when an AI answers is what each unwanted call costs. A spam call to a person wastes a minute of attention. A spam call to an AI agent is billed by the minute, by the voice platform, the model and the carrier, and the agent will politely keep talking for as long as the other side does.
Where the unwanted callers come from
Scraped listings
Business numbers are harvested from websites, maps and directories in bulk and sold as lead lists. Once your number is on a list, it gets dialed by everyone who buys that list: robocallers, telemarketers, and scripts testing which numbers answer.
The number's past life
Phone numbers get recycled. The number your platform assigned you may have spent years belonging to someone else, and it can still be on the lists that person was on. Some new lines take a steady stream of calls on day one for exactly this reason.
Dialing ranges
Autodialers don't need a list at all. They walk through blocks of numbers in order and note which ones pick up. A line that answers every call instantly, like an AI agent, stands out as a line worth calling again.
Shared demo and test numbers
"Call our AI now" numbers on landing pages, and test numbers shared in communities and screenshots, get passed around. They're the easiest AI lines in the world to find, and people call them to see what the AI will say.
People who found out an AI answers
Once someone learns a business has an AI on the phone, some will call just to play with it: pranks, attempts to make it say something it shouldn't, or to see how long they can keep it talking. A few do it with scripts.
Someone who wants to hurt you
The rarest case, and the most expensive: a competitor, an angry customer or anyone else with a reason points a script at your number and lets it run overnight. That's a call flood, and it costs you twice, in minutes billed and in real customers who can't get through while the lines are busy.
What they do once they're through
- Hold the line. Silent calls, recordings played into the agent, or a script talking in circles, each one billed by the minute.
- Fill your lines. Enough simultaneous calls and your real callers hear a busy signal or wait.
- Probe the agent. Try to get it to promise something, reveal something, or dial something. See refund promises and the pumping problem.
- Pollute your records. Fake bookings on the calendar, junk leads in the CRM, and cancellations of real appointments.
What you can actually do
You can't hide a business number, so the work is in noticing quickly and limiting the damage:
- Know what normal looks like for each of your numbers: calls an hour, typical length, where callers come from. A flood is only obvious if you know your baseline.
- Cap what a bad night can cost: concurrent calls, maximum call length, and a spend alert on every platform in the path.
- Watch for patterns, not just single numbers. Blocking one caller does little when a script rotates through many.
- Use what other businesses are seeing. The script calling you tonight is usually calling other businesses too. A caller already hitting a dozen other agents is a much clearer signal than anything your line sees alone.
- Get told on your phone, not the next morning in an inbox.
