Ever wonder why that unknown number keeps ringing your phone without ever leaving a message? It’s typically a hallmark of automated spam systems that rely on sheer volume rather than conversation. Since the caller never answers inbound calls and avoids caller‑ID, they’re likely testing whether your line is active. To protect your privacy, let the call go to voicemail, block the number after the first ring, and consider using a call‑filtering app that flags suspicious patterns. Regularly review your call log for repeat offenders and report persistent harassment to your carrier. Staying proactive keeps unwanted interruptions at bay.
Likely spam: the line repeatedly calls, never leaves a voicemail, and ignores calls with no caller ID.
