Should I block, answer or ignore unwanted calls?

It is strongly recommended not to answer unwanted calls. Here is why and how to react effectively.

Why not answer?

If you answer an unwanted call, the number will be considered valid by telephony systems and calling robots. This can lead to:

• More unwanted calls to your number
• Confirmation to spammers that your line is active
• An increased risk of more solicitations

The different options and their impact

• ✅ Block: Recommended solution. The call is automatically rejected and in the long run your number will be considered invalid.
• ❌ Answer: Avoid. It validates your number to spammers and encourages future calls.
• ⚠️ Ignore: Less effective than blocking. The number may call again, and your phone rings every time.

Answering is useless, even counterproductive

• Picking up and saying nothing: Useless. Automated systems detect the answer and mark your number as active.
• Insulting: Useless and risky. It does not deter robots.

About AI voice cloning

If you fear your voice being cloned for impersonation (spoofing):

• A simple "hello" is not enough to clone your voice.
• Several seconds of speech are needed for a recording to be usable. Roughly two or three sentences.
