The key to reducing spam phone calls
Official sources from digital security experts warn that the usual reaction of hanging up abruptly when receiving a call from a suspicious or telemarketing number can be counterproductive. These automated systems, based on artificial intelligence algorithms, interpret a quick hang-up as a signal that the number is temporarily unreachable but available, which encourages scheduling new calls in the near future.
Therefore, it is crucial to change how we respond to these calls to avoid feeding this cycle of phone harassment.
How automated calling systems work
Dialing and learning systems
Auto-dialing systems use algorithms that do not only dial numbers randomly but also learn from our behaviors. When we hang up abruptly, the system interprets that the number is receptive and schedules new calls.
How they adjust call frequency
These systems also analyze verbal responses or lack of interaction to classify numbers according to their likelihood of becoming customers. This explains why after a spam call, you often receive more similar ones.
Why you should not hang up abruptly: the strategy that works
Answer politely to deactivate the system
Instead of cutting the call immediately, experts recommend answering and responding courteously by indicating that you are not interested. This clear response is recorded as a definitive "no," discouraging future calls from that company.
Avoid providing personal information or answering questions
Maintaining privacy is essential. Do not provide data such as your name, ID, or banking details, and avoid answering questions that could be used to reinforce commercial profiling. Lack of verbal interaction is better than hanging up without responding.
Practical steps to reduce unwanted calls
Instructions to modify your response
- Answer the call instead of hanging up immediately.
- Respond with a brief "I am not interested" or similar, clearly and politely.
- Do not provide any personal data.
- Do not answer questions or interact beyond the initial "no."
- Register with the Robinson List to avoid authorized commercial communications.
- Enable call blocking options through your phone operator.
How to check if you are affected
- You receive repeated calls from unknown numbers or those identified as spam.
- If you hang up quickly and calls keep increasing, you are feeding the system.
- If you receive calls after having politely responded with a "no," the likelihood of being bothered decreases.
- You are registered with the Robinson List and unofficial calls persist: the problem might be illegal or international calls.
| Platform / Version | Affected | Solution available |
|---|---|---|
| Android and iOS Phones | Yes | Built-in blocking options and external apps |
| Phone Operators | Yes | Free blocking services and Robinson List |
Keeping the device and applications updated, activating two-step authentication, and reviewing app permissions are essential practices to avoid risks associated with fraudulent calls.
If you detect suspicious calls despite the measures, consider contacting your company’s customer service or filing a complaint with the Spanish Data Protection Agency.
The reality is that changing our response and taking advantage of the available legal and technological tools can make a big difference in reducing the constant nuisance of spam calls.
