Robocalls are more than just an annoyance—they disrupt workflow, waste time, and can even pose security risks. Small businesses, in particular, are frequent targets of spam and fraudulent calls, making it essential to have an effective strategy for blocking them. In this guide, we’ll walk you through the best ways to stop robocalls from interfering with your business operations.

1. Understand the Impact of Robocalls

Before taking action, it’s important to recognize how robocalls affect your business:

  • Lost Productivity: Employees waste time answering irrelevant calls.
  • Security Risks: Some robocalls are scams attempting to steal sensitive information.
  • Customer Frustration: Important calls may be missed due to a clogged phone line.

2. Register Your Business with the National Do Not Call Registry

The Federal Trade Commission (FTC) offers a Do Not Call Registry to help reduce telemarketing calls. While this won’t block all robocalls, it’s a helpful first step in reducing unwanted calls from legitimate telemarketers.

3. Use Call-Blocking Technology

Several tools and services can help automatically block robocalls:

  • Carrier-Based Solutions: Major phone carriers offer robocall filtering services. Check with your provider for options.
  • Third-Party Apps: Applications like Hiya, Nomorobo, and RoboKiller can detect and block spam calls.
  • Phone System Settings: Many VoIP and office phone systems have built-in spam filters.

4. Enable Call Screening

Call screening allows you to verify callers before answering. Consider these methods:

  • Automated Call Screening: Some services prompt unknown callers to press a number before connecting, deterring robocalls.
  • Receptionist Services: A virtual receptionist can answer calls and filter out unwanted ones, ensuring only legitimate callers reach your business.

5. Train Your Team to Recognize Spam Calls

Educating employees on common robocall scams helps prevent security breaches and wasted time. Some key tips include:

  • Avoid Answering Unknown Numbers: If a call seems suspicious, let it go to voicemail.
  • Never Share Personal Information: Scammers often impersonate banks or government agencies.
  • Report Suspicious Calls: Encourage employees to report robocalls to the FTC or phone carrier.

6. Report and Block Repeat Offenders

If robocalls persist, take these steps:

  • Block the Number: Most phone systems allow you to block specific numbers.
  • Report to the FTC: Submitting complaints helps regulators take action against robocallers.
  • Use Business Phone Solutions: Upgrading to a business-specific phone service with advanced call filtering can provide long-term protection.

7. Invest in a Professional Call Filtering Service

For the most effective solution, consider a call filtering service like Ascendist. These services screen incoming calls, block spam, and ensure that only important business calls get through—saving time and frustration.
