imp saved me from a scam call. Is there any way to report that number? March 17, 2022 23:21 Updated Yes, all numbers you suspect are scam calls, you can report to the Federal Trade Commission at this link: FTC.gov Related articles My imp is in screening mode, but greenlist messages are not being left on my answering machine. My LEDs are not flashing but one is green and one is red. What do I need? (What requirements do I have to have to use an imp box?) imp is reporting the wrong caller ID. How does imp know which numbers to allow through?
