A silent call to your landline with background noises that hinted at someone trying to speak but not succeeding calls for caution, especially from a number appearing local like from Monterrey. These kinds of silent or dubious calls often serve as probes to verify if lines are active, potentially leading to more aggressive spam or even scam attempts later. Hang up immediately without engaging, and consider registering your number on do-not-call lists to reduce unwanted contacts. Block the number if possible, and report it to your telecom provider for further monitoring. Staying vigilant helps protect against escalating nuisances.
Precaución: recibí una llamada silenciosa de un número que parece local a Monterrey, con ruido de fondo pero sin hablar.
