Missed call text back: what happens the moment a call goes unanswered

Quick answer

Agent Studio turns a missed call into a conversation within seconds. When a call to your number goes unanswered, the caller is texted back from that same number, the missed call is pinned to the top of their conversation, and the Missed call trigger fires so workflows open a call-back task, tag the contact or alert your team.

What you'll have

  • Every unanswered caller texted back from your business number within seconds.
  • A call-back task for your team on every missed call.
  • Missed calls visible in Calls, Conversations and the contact record.

What exactly happens when I miss a call?#

A call counts as missed when it is inbound, nobody picks up, and no Voice AI agent handled it: it rang out, the line was busy, the caller hung up while it rang, or they left a voicemail. The moment the phone company reports that, Agent Studio runs this sequence.

  1. The call is logged in Calls with its outcome (no answer, busy or voicemail), source and any recording.
  2. The caller is found or added as a contact, and the missed call is placed at the top of their conversation in Conversations.
  3. If Text back missed callers is on for that number, the caller gets your text-back message from the same number within seconds.
  4. The Missed call trigger fires with the call and whether the caller was texted, so any workflow you built runs next.

How do I turn on missed call text back?#

Turn it on for the number's text channel, write your message, and optionally add the starter workflow for the call-back task.

The default message

Out of the box, callers get: "Sorry we missed your call. How can we help? Reply here and we will text you right back." Make it yours: name the business, mention a booking link, or tell them when to expect a call.

Will a caller ever get spammed or texted twice?#

No. Agent Studio builds the guardrails in so text-back stays welcome.

Text-back rules Agent Studio enforces
SituationWhat Agent Studio does
The same caller rings again within 30 minutesOne text, not two
The caller texted STOP beforeNo text; do-not-disturb is honored
The caller's number is hiddenSkipped, with the reason logged
The channel text-back and the starter workflow are both onThe workflow checks whether the caller was already texted and sends only one
A Voice AI agent answeredNot a missed call: the agent booked, transferred or took a message

Every call records its text-back result (sent, failed, blocked, skipped or off) with the reason, so you always know why a caller did or did not get a text.

Can I follow up missed calls on WhatsApp or with a workflow?#

Yes. The Follow up missed calls on WhatsApp starter messages contacts already on WhatsApp, using your approved template outside the reply window, and opens a call-back task. Or build your own on the Missed call trigger in Automations: tag the contact, move them into a pipeline stage, post to Slack, or start a nurture sequence.

That is 13 booked jobs a month going to whoever picks up first. An AI receptionist answers every call, day or night, and books the job while the caller is still on the line.

Questions buyers ask#

How fast does the missed call text go out?

Within seconds of the phone company reporting the unanswered call. The text comes from the same number the customer called, so their reply lands in your Conversations inbox.

Does missed call text back work if the caller leaves a voicemail?

Yes. A call that ends in voicemail still counts as missed, so the caller gets the text and your team gets the voicemail on the call in Calls.

Can I personalize the missed call text?

Yes. Use {first_name} and {business_name} in the message. A caller not yet in your CRM is greeted as "there", and the business name comes from your CRM settings.

Is missed call text back compliant with texting rules?

Agent Studio honors STOP replies and do-not-disturb on every text-back, and US numbers send through your A2P 10DLC registration, which you complete in Phone setup.

Where is missed call text back in GoHighLevel vs. Agent Studio?

GoHighLevel keeps it in phone settings. In Agent Studio it is a checkbox on the number's SMS channel under Conversations, plus a ready-made Text back missed callers workflow for the call-back task.
