Set Up Missed Call Follow Up in GoHighLevel

The Problem: Every Missed Call Is a Lost Customer

A missed call is a missed customer. When a prospect calls your business and no one answers, they do not leave a voicemail and wait — they call the next business on the list. The lead you paid to generate is gone in under sixty seconds.

Missed-call text-back is the single highest-ROI automation most service businesses can deploy. When a call goes unanswered, GoHighLevel automatically texts the caller within seconds, acknowledging them and opening a conversation. It takes about fifteen minutes to set up, and it immediately recovers leads that would otherwise be permanently lost.

Two Ways to Set It Up

GoHighLevel offers two approaches:

1. The built-in Missed Call Text Back setting — a simple toggle in Phone System settings that sends a static message to every missed caller. 2. A custom Workflow — more control, with deduplication logic to avoid texting the same caller multiple times if they call repeatedly.

The built-in setting is the fastest path. The workflow version is better for businesses that get repeat missed calls from the same number.

Method 1: The Built-In Setting (Fastest)

Step 1: Navigate to Phone System settings

In your sub-account, click Settings in the bottom-left corner. In the left menu, select Phone System, then the Voice tab, then open Voicemail & Missed Call Text Back.

Step 2: Enable the feature

Select the checkbox to Enable Missed Call Text Back.

Step 3: Customize your message

Click Customize and write the message that goes out when a call is missed. Keep it short, warm, and action-oriented:

"Hi, this is [Company]. Sorry we missed your call! How can we help you today? If you'd like to book an appointment, here's our calendar: [booking link]"

You can use the custom value icon to insert the contact's name dynamically.

Step 4: Set the call timeout

Use the slider to choose how long the phone rings before a call counts as "missed." Ten to twenty seconds is typical. A very long timeout delays the text-back; a very short one may cut off callers who would have answered.

Step 5: Send a test and save

Select a number to preview how the message appears, then click Save. The next time an inbound call goes unanswered past your timeout, the caller receives your message automatically.

Method 2: The Workflow Version (Smarter)

The built-in setting sends a text for every missed call — even if the same caller tries three times in five minutes. To avoid sending multiple messages, build a custom workflow.

Step 1: Create a new workflow

Navigate to Workflows and create a new workflow. Name it "Missed Call Text Back — Smart."

Step 2: Set the trigger

Set the trigger to Call Status and select the statuses "Busy," "No Answer," and "Voicemail." This fires the workflow only when a call genuinely goes unanswered.

Step 3: Add a wait step

Add a Wait step of about twenty minutes. This gives the caller a window to call back without triggering a second text.

Step 4: Add a condition

Add a conditional branch: only proceed if the contact does not already have a tag like "missed-call-contacted." This prevents duplicate texts to repeat callers.

Step 5: Send the SMS

Add a Send SMS action with your message. Include your booking link so the caller can self-serve an appointment.

Step 6: Tag the contact

Add an Add Tag action with "missed-call-contacted" so the next missed call from the same number does not trigger another text.

Step 7: Create an opportunity

Optionally, add a Create/Update Opportunity action to drop the contact into your pipeline so the lead is tracked, not just texted.

Important: Register A2P 10DLC

This is the step that causes the most support tickets. Without A2P 10DLC carrier registration, major US carriers silently filter business text messages. Your text-back fires, but the message never reaches the caller.

Register your business and your phone numbers through the A2P 10DLC process in GoHighLevel's phone settings before relying on any SMS automation.

Testing Your Setup

Before going live, test from a different phone number:

1. Call your GoHighLevel number and let it ring past the timeout 2. Hang up without leaving a voicemail 3. Confirm you receive the text-back message within seconds 4. Call again immediately and confirm you do not receive a duplicate (if using the workflow version)

If the text does not arrive, check A2P registration first — it is the cause nine times out of ten.
