Mitigating Unsolicited Calls

Identifying Potentially Fraudulent Calls

Several characteristics can indicate a potentially fraudulent call. These include calls from unknown numbers, requests for personal information (bank details, social security numbers, passwords), aggressive or high-pressure sales tactics, and promises of unrealistic rewards or opportunities. Calls with automated messages (robocalls) often precede fraudulent activities.

Utilizing Telecommunication Features

• Call Blocking: Many telephone services offer call blocking features, allowing users to block specific numbers or numbers matching certain patterns (e.g., area codes known for scams). Some services provide automatic blocking of suspected fraudulent calls based on caller ID analysis.
• Do Not Call Registry: Registering with the national Do Not Call Registry may reduce the number of unsolicited marketing calls, although scammers often disregard this registry.
• Answering Machine/Voicemail: Using an answering machine or voicemail can help screen calls, allowing you to review messages before answering unknown numbers.

Mobile Device and Application Settings

• Contact Filtering: Some mobile operating systems allow for filtering of calls based on contact lists or unknown numbers. This often involves directing unknown numbers to voicemail or blocking them altogether.
• Call Identification Apps: Numerous applications use caller ID databases and community reporting to identify and flag potential spam or fraud calls.
• Spam Filters: Many communication applications incorporate spam filters to detect and automatically block suspected fraudulent calls or messages. However, effectiveness may vary.

Best Practices for Call Handling

• Never provide personal information: Legitimate organizations will not request sensitive data over the phone.
• Verify caller identity independently: If a caller claims to represent a specific organization, hang up and verify their identity through official channels (website, official phone number).
• Be cautious of high-pressure tactics: Legitimate businesses rarely employ aggressive sales techniques.
• Report suspected fraud: Report suspected fraudulent calls to the appropriate authorities (e.g., Federal Trade Commission).

Technological Advancements in Call Security

Ongoing technological developments aim to improve call authentication and fraud detection. These include techniques like STIR/SHAKEN (Secure Telephone Identity Revisited/Signature-based Handling of Asserted information using toKENs) designed to verify the origin of calls.
