⚡Quick answer -
A Missed Call Service lets customers dial your virtual or toll-free number, disconnects after 1–2 rings (so they pay nothing), and instantly triggers an action—send an SMS or WhatsApp template, queue a callback, or fire a webhook that logs the lead in your CRM.
When should I use this guide?
Use these steps if you need a zero-cost, one-touch way for prospects to opt in to offers, register for events, verify numbers, or request a callback—without writing custom code.
1 — Why choose a missed-call workflow?
• Free for callers—higher opt-in rates from ads, TV, radio, or print.
• Instant automation—lead capture, SMS/WhatsApp reply, or CRM push.
• Works on every phone—no data plan or app required.
2 — Eligibility & prerequisites
Requirement | Where to confirm | Notes |
Virtual mobile or toll-free number | Dashboard → Numbers | Must allow missed-call routing |
Dashboard or API access | MyOperator account | Admin or Dev role |
Defined post-call action | Campaign brief | SMS/WhatsApp template, webhook URL, or callback queue |
(Optional) CRM integration | Integrations → CRM | Map Caller Number, Campaign, UTM Source |
3 — Enable a Missed Call Service in the Dashboard
- Navigate to Engagement → Missed Call → Create Campaign.
- Choose your virtual/toll-free number.
- Set Ring Limit = 1–2 rings to guarantee no caller charge.
- Configure Deduping Window (e.g., 15 min) to ignore rapid repeats.
- Pick the post-call action:
Action | Configuration |
Send SMS/WhatsApp | Select an approved template |
Queue callback | Pick Agent Queue |
Trigger webhook | Enter HTTPS endpoint |
- (Optional) Map CRM fields and add consent text shown in ads/SMS.
- Click Save & Publish—your campaign is live.

5 — Testing & success checklist
- From any phone, call +1-800-555-8080 (campaign number).
- Call drops after ≤ 2 rings.
- Dashboard → Activity → Missed Calls shows a log within 5 s.
- Dashboard → Activity → Outgoing Messages shows the SMS/WhatsApp reply.
- If using a webhook, your server logs a 2xx response.
Expected outcome:
• Lead/event record created.
• Caller receives the reply or sits in the callback queue.
• Analytics increment by one interaction.
6 — Edge cases & limitations
• DND or opted-out numbers: you may log the call, but cannot message them.
• Masked caller IDs: some networks hide numbers—lead capture fails in that case.
• International traffic: confirm your number accepts it; messaging rules differ by country.
• Network quirks: older networks may delay event triggers; monitor latency.
• Consent: ad or landing page must state that a missed call equals consent to contact.
7 — Troubleshooting
Symptom | Likely cause | Fix |
No event logged | Number not tied to campaign or ring limit > 2 | Re-assign number, set ring limit to 1–2 |
Webhook didn’t fire | Endpoint not whitelisted or returns non-2xx | Allow HTTPS POST, return 200 |
SMS not delivered | Template unapproved or user opted out | Approve template, honour opt-out |
High duplicates | Deduping window too small | Raise to 15–30 min |
Callback fails | No agents online | Check agent availability & queue rules |
