How Do I Set Up Missed Call Text Back in GoHighLevel?

Checked against HighLevel’s help center on October 17, 2026. HighLevel updates its interface often, so match the labels you see on screen.

Turn it on

1. 1In the sub-account, click Settings, then Phone System
2. 2Open the Voice tab, then Voicemail & Missed Call Text Back
3. 3Click Missed Call Text Back in the side panel and check Enable Missed Call Text Back
4. 4Click Customize and type your text in the Enter message field. Custom values like the contact’s name only fill in for contacts HighLevel already knows.
5. 5Send a test to your own phone, then click Save

The incoming call timeout in the voicemail settings decides when a call counts as missed, and HighLevel recommends 10 to 20 seconds. Answered calls never trigger a text.

Which number sends the text

HighLevel first tries the number the caller dialed. If that number can’t send SMS, like a number pool or an unverified toll-free number, it falls back to a number that has texted the contact before, then your default outbound number, then any other eligible number. If none qualify, the failed attempt and its reason show in the conversation.

• Every text counts toward the sub-account’s daily SMS limit
• Contacts on DND don’t get the text
• The text goes out after every missed call, even when the same person calls again minutes later

Build it as a workflow instead

To stop repeat texts, HighLevel suggests a workflow version with a Wait step, or tags that mark 1st and 2nd calls.

1. 1In Automation → , then Workflows, create a workflow and add the Call Details trigger
2. 2Set Call Direction to Incoming and Call Status to busy, voicemail, or no-answer
3. 3Add a Send SMS action with your message, plus the Wait step or tag filter
4. 4Turn on Allow Re-entry in the workflow settings so a repeat caller can enroll again after the first run ends
5. 5Test with a real call, then publish
