People silence unknown callers to escape spam, then miss important calls
People who need to remain reachable to legitimate unknown callers struggle to filter spam without silencing everyone outside their contacts. Built-in spam labels and broad unknown-caller settings do not always offer the selective control they want, and unwanted callers can still leave voicemail. Some respond by letting every call go unanswered, which risks missing time-sensitive calls from work, banks, courts, or other institutions.
For smartphone users who need to answer legitimate calls from unknown numbers. Mentioned from Oct 2023 to Aug 2026 on Bluesky, Hacker News and Stack Exchange.

If I could just block the numbers, or auto send to voicemail, that my phone already flags as Spam/Telemarketing this wouldn’t be so frustrating for me. I do need my phone to ring for unknowns/outside my contacts numbers, so the blocking ability I need isn’t available (on iOS anyway.)
Right now, I’m on a strict “no-ring” policy: if a call turns out to be legitimate, I’ll call back. But nobody gets real-time PSTN access to me anymore—it’s simply not sustainable
