Quick Answer

A missed call alert service gives your business a dedicated phone number that customers call and that disconnects automatically, so the call is free for them. The caller's number is logged, an automatic SMS or WhatsApp reply goes out, and the lead is sent to your dashboard, email or CRM. Uses include lead capture, opt-ins and number verification.

How a missed call alert service works

Everything happens in a few seconds after the caller hangs up.

StepWhat happens
1. You publish a numberOn ads, hoardings, packaging, TV, print, your website or an SMS.
2. Customer gives a missed callThe call rings and is cut automatically, so the caller is not charged.
3. Number is capturedThe caller's mobile number, time and campaign are logged in your dashboard.
4. Instant replyAn automatic SMS or WhatsApp message goes out: a thank-you, brochure link, coupon or confirmation.
5. Lead reaches your teamThe lead is pushed to your CRM or app through API or webhook, or sent to your sales team by SMS or email.
Use cases

What businesses use missed call alerts for

Lead capture from ads

Print, outdoor, TV and radio ads get a simple call to action: give a missed call.

Opt-in for SMS and WhatsApp

Build consent-based lists for campaigns such as WhatsApp broadcasts.

Phone number verification

Verify a number without typing a code using missed call OTP.

Callback requests

Customers ask for a call back; your team is alerted and calls them.

Polls, votes and contests

One missed call counts as one vote or one entry.

Rural and feature-phone reach

Works on any phone without internet or an app.

Instant replies on SMS and WhatsApp

The reply is what turns a missed call into a conversation. You can send a DLT-approved SMS (for example, a thank-you with a brochure link), a WhatsApp message with buttons or a catalogue, or both. On WhatsApp, the reply can start a WhatsApp chatbot flow that answers questions or books an appointment.

SMS replies in India follow the normal DLT rules: the sender ID and the reply text must be registered as a template, and any link must be whitelisted. Our team sets this up with you. See bulk SMS rules in India for the details.
