Block suspicious numbers promptly and let the call go to voicemail whenever possible. Quiet background noise and vague accents often signal automated or low‑quality outbound campaigns. Let the call end naturally; avoid engaging or providing personal details. If the number repeats, consider adding it to your device’s block list or reporting it to your carrier’s spam‑call service. Use a call‑screening app that flags likely telemarketing sources. Regularly review blocked‑call logs to catch patterns, and educate household members about the risks of answering unknown numbers. Stay vigilant and keep your contact information private.
A silent caller droned with indistinct noises that resembled Chinese or Indian sounds; after five minutes I realized it was fake and ended the call.
