Caller ID spoofing is getting worse, not better. Scam and telemarketing calls have climbed to 2.56 billion per month, up 20% year-over-year, and even the FCC's STIR/SHAKEN framework can't fully protect you — only 44% of phone companies have fully implemented it, and spoofers have learned to game the highest trust levels. That means the practical defense isn't waiting on carriers; it's watching for the warning signs yourself: "Spam Likely" labels, dropping answer rates, and complaints about calls your business never made. Check your number's reputation with free lookup tools, dispute false flags with carriers and blocking apps, and ask your voice provider whether they sign calls at full attestation and enforce Do Not Originate rules. The businesses that stay ahead treat spam screening as part of lead response, not an afterthought. CallMyLeads screens known spam and robocalls before they waste your team's time — and those minutes are never billed, so you only pay when a real lead is actually handled. Book a free 15-minute scoping call and stop paying for leads you never get to talk to.
