If you run a small business, your number is everywhere: your website, your truck, your map listing. That's how real customers find you. It's also how robocalls and sales pitches find you. Every spam call you answer costs you a few minutes and your focus. The worst part is that you can't tell which ringing phone is a customer until you answer. There are three steps that cut most of them down.
Step 1: Use what your phone already has
Your phone and your phone company have free tools. The FTC lists the main ones in its guide How To Block Unwanted Calls:
- Block numbers you know are spam
- Turn on your phone's built-in call filtering
- Ask your phone company about call blocking or call labels
- For robocalls, hang up and don't press any numbers
These help, but they work best on numbers that are already known as spam. New numbers still get through, and spammers change numbers all the time.
Step 2: Keep sales calls away from you
The hardest calls to block are real people selling something: ads, SEO, loans, "a quick question about your listing." They call from normal numbers, so filters often miss them.
This is where an AI receptionist helps. Cally answers, listens to what the caller wants and spots robocalls and sales pitches. Then it ends the call politely, and the pitch stays away from you.
You can still see these calls in your dashboard, marked as spam or sales, if you ever want to check.

Step 3: Make sure real customers still get through
The risk with blocking is blocking the wrong person. A new customer calling from an unknown number looks just like a spammer to a filter, and sending every unknown number to voicemail loses exactly the callers you want.
Cally doesn't guess from the number alone. It talks to the caller first. If it's a real customer, it books them in or takes their details and sends you the lead.
What works best
Each tool handles a different part of the problem, so most businesses use more than one:
| Blocks known spam | Stops sales pitches | Real customers get through | |
|---|---|---|---|
| Blocking numbers by hand | Some | No | Yes |
| Phone filtering apps | Many | Some | Usually |
| Sending unknown callers to voicemail | Yes | Yes | Often lost |
| Cally24 | Yes | Yes, ended politely | Yes, and you get the lead |
How Cally ends a spam call
Cally keeps it short and polite. For a sales pitch, it says the business isn't interested and ends the call. For a robocall, it simply ends it. There's no argument and no wasted minutes for you.
What a morning looks like
At 9:10 AM, a caller offers to put your business at the top of search results. Cally hears it's a sales pitch, says the business isn't interested and ends the call. At 9:25 AM, a robocall about a loan is ended in seconds. At 9:40 AM, an unknown number calls. It's a new customer who wants a quote, and Cally books them in.
You were on a job all morning. Your phone stayed quiet for the two spam calls, and the one real customer is waiting in your inbox as a lead.

Common questions
Can Cally block a real customer by mistake?
Cally talks to every caller before it decides. If someone sounds like a customer, it treats them like one. You can also check the spam list in your dashboard any time.
Can I tell Cally to let some sales calls through?
Yes. If you want to hear from your suppliers, for example, tell Cally in your dashboard and it will take their message.
Does joining the Do Not Call Registry help?
The FTC says the registry is meant to stop sales calls from companies that follow the law, but it won't stop scammers. It's worth doing, just don't count on it alone.
