What's the Best Way to Set Up Missed Call Text Back?

By GHL Scaleup Team  •  GoHighLevel setup specialists  •  Updated July 2026

What Missed Call Text Back Actually Is

Missed call text back is a workflow that fires an automated SMS the second a call goes unanswered. Instead of a caller hanging up and hearing nothing back, they get an instant text something like "Sorry we missed you, how can we help?" before they've even put the phone down.

It matters because of what happens next if that text doesn't go out. A missed call from a plumber, dentist, real estate agent, or contractor is a lead that's actively looking for help right now. If nobody follows up in the next few minutes, that lead calls the next business on the list. Missed call text back closes that gap automatically, without anyone having to remember to call back.

When Do You Use Conditional Call Forwarding?

Here's the scenario this setup solves: a client wants missed call text back running on their business, but they will not port their number over to a new provider, and they don't want every single call routed through a new system before it ever reaches them. Those two conditions rule out most of the "easy" integrations, and that's exactly when Conditional Call Forwarding is the right call.

Conditional Call Forwarding is a carrier-level setting, not a GHL feature. It tells the client's mobile carrier Verizon, AT&T, T-Mobile to reroute a call only under specific conditions: the line is busy, nobody answers, or the call is declined. Every other call behaves exactly as it did before. That's what makes it different from standard call forwarding, which redirects every incoming call regardless of whether it's answered.

Here's what the call flow looks like once it's live:

• Someone calls the client's normal business number
• The client's phone rings like always nothing changes for the caller
• If the call isn't picked up (busy, no answer, declined), the carrier forwards it to a dedicated GoHighLevel number
• GoHighLevel answers, plays a short voicemail greeting, and fires the missed call text back workflow to the caller

The client never touches a new device, and the number on the client's business cards, Google Business Profile, and website stays exactly the same.

How to Set Up Missed Call Text Back With Conditional Call Forwarding

Setting up missed call text back this way comes down to two steps: build the automation in GoHighLevel first, then point the carrier at it.

Step 1 Build the missed call automation in GoHighLevel. Before you touch the client's phone, buy a local phone number in GHL (same area code as the business), upload a voicemail greeting, and build a workflow triggered by call status Busy, No Answer, or Voicemail that fires an SMS the moment a call is missed. This is the automation that actually sends the text back.

Step 2 Set up conditional call forwarding on the carrier side. This is one dial code, entered once on the client's mobile phone, and the call forwarding setup is done. Each mobile carrier uses a slightly different code:

They dial it like a phone call, hit call, and hear a confirmation tone. That's it the safety net is live.

Two Things Worth Knowing Before You Turn On Conditional Call Forwarding

Personal voicemail gets swept up too. If the client uses their personal cell phone for business calls, conditional call forwarding doesn't separate personal calls from business calls every missed call on that device routes to the GoHighLevel number. Most clients are fine with this trade-off once it's explained. If it's a concern, a dedicated business line for the missed call text back setup avoids the overlap entirely.

Don't forward the GoHighLevel number back to the client's cell phone. Doing that creates a call loop the call bounces between the carrier and GoHighLevel and never actually resolves. The GoHighLevel number should catch the call, play the voicemail greeting, and stop there. No forwarding past that point.

How to Explain This to a Client (Without Losing Them)

Don't lead with "we're taking over your phone system" that's the sentence that makes clients hesitate. Try this instead: "We're installing a safety net. Your phone works exactly like it does today. But when you're busy or on a job, instead of a dead-end voicemail, our system catches the lead and texts them back instantly, before they call the next business on the list."
