AI Inbound Spam Filter & IVR Verification System
A multi-stage GoHighLevel IVR workflow that verifies real callers, blocks spam and robocalls, tags returning customers, routes genuine calls, and records voicemails — so business owners only ever pick up for real people.
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
- 1
Incoming Call Trigger
Workflow fires on every inbound call to the business number.
- 2
Check IVR Verified Tag
Contact is inspected for a prior 'ivr-verified' tag.
- 3
Verified Caller → Connect Directly
Returning verified callers skip IVR and are routed straight to the business.
- 4
New Caller Enters IVR Verification
Unknown callers are sent into a Gather-input IVR step.
- 5
Prompt: Press a Key to Continue
A short audio prompt asks the caller to prove they're a real person.
- 6
Key Pressed → Verify & Connect
Apply verification tag, connect the call, and save the state for future calls.
- 7
No Key Pressed → End Call
Spam and robocalls are ended silently before staff are ever interrupted.
- 8
Unanswered Verified Call → Voicemail
If the business can't pick up, the workflow records a voicemail and ends cleanly.

An end-to-end playbook I run for clients: design and vibe-code a high-converting landing page inside AI Studio (Lovable), then wire its submission form to a GoHighLevel sub-account through a custom webhook using the sub-account's API token + location ID. Every external lead — from ads, SEO, referrals, anywhere — is pushed into GHL as an authenticated contact, tagged by source, dropped into the right pipeline stage, and triggers the full automation stack (welcome email, internal alert, SMS, nurture sequence).
