Missed-Call Text-Back · $199 · 3 business days after access · Coming soon

A missed call shouldn't be a lost customer.

We set up an automation for one business number: when you miss a call, the caller gets a text (SMS, or WhatsApp where they've opted in) with a booking link or a promise to call back, and voicemails are transcribed and summarised to your email or phone. It's the cheapest first step before a full AI receptionist.

Missed-Call Text-Back is a fixed-price service from ChikuOS, run by Siddharth Mishra, an independent developer in India. Every missed call gets an instant text back, and every voicemail becomes a short written summary. It is planned at $199 with a turnaround of 3 business days after access, but it isn't available to buy yet.

What you get

Texts go only to people who just called you, and every message honours STOP opt-outs. US texting requires A2P 10DLC registration, and carrier approval can take days to weeks, which is outside our control and not counted in the 3 days. You pay Twilio or your provider's messaging and number costs directly.

Who it's for

FAQ

Do I need SMS opt-in?

Texts go only to people who just called you, and every message honours STOP. WhatsApp replies are used only where the caller has opted in.

What is 10DLC?

US carriers require businesses texting from a normal 10-digit number to register a brand and campaign (A2P 10DLC). We help you register; carrier approval time isn't in our control.

Who pays for texts?

You pay your provider's messaging and number costs directly.
