Here's exactly what happens on every call — no apps to install, nothing for you to manage.
Someone dials your business number. It rings once, same as always.
A short prompt asks for a touch-tone response: press 1 to connect.
listening for DTMF '1'Tone detected → rings through instantly. No tone → call ends silently.
no signal → call droppedTrade businesses get hit harder than most. Your number is public, and agencies selling websites, "free SEO audits," and marketing packages call down entire lists of contractors, handymen, and lawn care companies every day. It's not personal. It's just volume.
SpamShield doesn't ask you to screen your own calls or block numbers one by one. The gate does that sorting before the call ever reaches you.
A real customer hears the prompt and presses 1 without thinking twice. Sales campaigns running through auto-dialers almost never do — most aren't built to respond to a prompt at all.
The result: your phone still rings for the jobs. The pitches don't get through.
