What is a Missed Call Service?
A WALOOP Missed Call Service turns a single published phone number into a zero-cost lead-capture channel. The caller's phone rings once and disconnects automatically, at no cost to them, while WALOOP instantly captures their number and campaign context and pushes it wherever your team works.
Free for the Caller
The call rings once and auto-disconnects before it connects, so the customer never pays a rupee or a minute.
Sub-500ms Webhooks
Caller data lands on your CRM or server in under half a second — fast enough to call back while intent is still hot.
Configurable Payload
Design your own JSON payload with placeholders like %caller%, %circle%, %operator%, and %campaign% to fit any endpoint.
Instant Follow-Up
Trigger an automatic WhatsApp or SMS reply the moment a call lands, keeping the caller engaged while they wait.
DND-Friendly by Design
Because no call ever actually connects, the channel works even for numbers registered on DND lists.
Duplicate Filtering
Repeat calls from the same number within a configurable window are automatically deduplicated before they reach your CRM.
Per-Campaign Tracking
Assign a unique number or tag to every ad, hoarding, or packaging run and see exactly which one drives calls.
Measurable ROI
Compare cost per lead across print, outdoor, and digital campaigns using the same real-time missed call data.
Everything a missed call number needs to convert
