AI Inbound Spam Filter & IVR Verification System

The Challenge

Local businesses were drowning in spam calls and robocalls. Staff wasted hours answering unwanted callers, and real customers were being missed inside the noise. The client needed a fully automated verification layer between the world and the business phone.

The Solution

I designed a multi-stage GoHighLevel IVR automation that classifies every incoming call. Already-verified callers skip verification and connect straight through. New callers enter an IVR challenge: press a key to prove you're a real person. If they pass, a verification tag is applied, the call is connected, and future calls bypass verification. If they fail, the call is ended before it ever interrupts staff. If a verified caller isn't answered, the workflow records a voicemail for follow-up.

Step-by-step, exactly how the automation runs

Incoming Call Trigger

Workflow fires on every inbound call to the business number.

Check IVR Verified Tag

Contact is inspected for a prior 'ivr-verified' tag.

Verified Caller → Connect Directly

Returning verified callers skip IVR and are routed straight to the business.

New Caller Enters IVR Verification

Unknown callers are sent into a Gather-input IVR step.

Prompt: Press a Key to Continue

A short audio prompt asks the caller to prove they're a real person.

Key Pressed → Verify & Connect

Apply verification tag, connect the call, and save the state for future calls.

No Key Pressed → End Call

Spam and robocalls are ended silently before staff are ever interrupted.

Unanswered Verified Call → Voicemail

If the business can't pick up, the workflow records a voicemail and ends cleanly.
