Twilio Missed Call Text-Back + Telegram Alerts (n8n Workflow)

Turn missed calls into instant SMS text-backs—plus Telegram alerts in n8n

This n8n workflow uses Twilio webhooks to detect when an inbound call was missed and automatically sends the caller a tailored SMS text-back. At the same time, it notifies the business owner via Telegram so no missed opportunity slips through.

What this workflow does

• Receives inbound call events from Twilio through a webhook.
• Responds with TwiML to forward the call to your main phone number and instruct Twilio to post the dial outcome to a second webhook.
• Handles the dial status callback and acknowledges it immediately.
• Checks Twilio’s DialCallStatus and continues only when the call was missed (including no-answer, busy, failed, or canceled).
• Suppresses repeat callers so the same phone number receives only one text-back within a two-hour window.
• Generates a message for after-hours vs. during-hours using your configured business name, timezone, and opening hours.
• Sends the SMS to the caller via Twilio.
• Alerts the owner in Telegram with a missed-call notification.

Use cases

• Your office routes calls, but when someone can’t reach you, they receive an immediate SMS with next steps.
• After-hours callers get an after-hours text-back without manual effort.
• Owners stay informed via Telegram the moment a missed call happens—ideal for small teams and SaaS operators.
