A Missed Call Does Not Have to Become a Lost Enquiry
People often call several businesses when they need a quick answer. A concise follow-up acknowledges the missed call and offers an immediate way to share what they need.

Invite the caller to reply with the service, appointment or enquiry details.
Route the Lead
Make the follow-up conversation visible to the responsible person or workflow.
Avoid Repetition
Apply a cooldown so repeated calls do not create excessive responses.
How detection works
The Missed Call Must Reach Your AutoForward Text Virtual Number
Use the virtual number as the number customers call, or configure no-answer call forwarding with your carrier. When an unanswered call reaches that virtual number, it can trigger the configured follow-up.
Keep an existing business number by forwarding only unanswered calls.
Use the AutoForward Text virtual number directly for a new business line.
Trigger the response only after the missed call event is received.
Important: the feature does not scrape an unrelated phone’s call history. Calls must route to the configured virtual number.

- Applicable sender registration and destination support
- Balance, carrier fees and compliance remain with Twilio

Send the acknowledgement through a supported connected WhatsApp account when the caller is reachable there.
- Connected WhatsApp account required

Keep the Follow-Up Helpful, Short and Human
A useful missed call message acknowledges what happened, identifies the business when necessary and makes the next step obvious.
Example
“Sorry we missed your call. Please reply with your name and what you need, and our team will get back to you shortly.”
✓ Send after a short delay so the response feels connected to the call.
✓ Limit repeat messages if the same caller tries again.
✓ Make sure a real person or monitored workflow can receive the reply.
✓ Include appropriate opt-out wording where required.

Missed call FAQ
Missed Call Text Back Questions
The virtual number, forwarding route and outbound channel must all be configured correctly.
Explore Call AnalyticsWhat is missed call text back software?+
Missed call text back software automatically sends a short follow-up message after a caller reaches a configured business number and the call is missed. It gives the caller a way to continue by SMS or WhatsApp.
How does AutoForward Text detect a missed call?+
The missed call must reach an AutoForward Text virtual number, either because the caller dialed it directly or because an existing business number forwarded an unanswered call to it. AutoForward Text does not secretly read an unrelated phone’s call history.
Can I use my existing business number?+
Yes. Configure no-answer call forwarding with your carrier so unanswered calls to the existing number are sent to the AutoForward Text virtual number that triggers the workflow. Carrier support and charges may vary.
Can the automatic response be sent by SMS?+
Yes. Connect a Twilio number that is enabled for outbound SMS. The customer is responsible for sender registration, balance, destination support, recipient consent and applicable messaging rules.
Can the missed call response be sent through WhatsApp?+
Yes. A supported connected WhatsApp account can send the follow-up when the caller is reachable on WhatsApp and the selected connection complies with applicable WhatsApp messaging requirements.
Will the same caller receive repeated messages?+
Timing and frequency limits can reduce repeated responses when the same person calls more than once. Configure a suitable delay and cooldown, then test the behavior before enabling it for customers.
Is missed call text back the same as voicemail?+
No. Voicemail lets the caller leave a recording. Missed call text back sends an SMS or WhatsApp acknowledgement and invites the caller to continue in writing. A business may use both workflows together.
Can I use missed call text back for cold outreach?+
No. This feature is intended to respond to people who called the business. It should not be used to send unsolicited marketing, evade consent rules or contact purchased lists.
