Silent calls from unknown numbers, especially repeated within a day, often signal automated robocalls or potential harassment tactics. In areas like North America, where this pattern is common, such voicemails are typically empty to gauge if the line is active, potentially leading to more spam. Hang up immediately without responding—engaging confirms your number is live. Block the caller via your phone settings or carrier tools to prevent further contact. Report to authorities like the FCC if it persists, as it may violate telemarketing rules. Enable spam filters on your device for added protection against these nuisances.
Got two calls from this number in a single day, and every voicemail is completely silent, lol.
