How is India forcing the fight against spam calls?

India is now requiring caller-ID apps to feed their spam reports directly to phone carriers — a regulatory push to choke off the country’s flood of unwanted calls at the network level instead of one phone at a time. Why it could work: carriers see call patterns across millions of lines, so shared spam data lets them block a scam campaign’s numbers before your phone ever rings. For the rest of us, the takeaway is defensive: switch on your carrier’s spam-blocking tools, never trust caller ID alone (numbers are trivially spoofed), and let unknown calls go to voicemail — legitimate callers leave messages.
