Missed call text back
Also called missed call auto text, text back on missed call.
Missed call text back is a phone feature that sends an automatic text to someone whose call you didn't answer, usually within a minute. The text says you saw the call and invites them to reply, so the conversation keeps going by text. In the US it runs on business texting rules, which means registering your number and respecting consent.

How it works
Your business line runs through a phone system that can send texts. When a call rings out or goes to voicemail, the system texts the caller something like: 'Sorry we missed you, this is Oak Street Plumbing. What do you need help with? Reply here and we'll get back to you.'
The appeal is simple. Many people won't leave a voicemail, and a caller who hears nothing will dial the next company on the list. A text gives them a way to keep going without waiting on hold or calling back.
Two limits are worth knowing. It only works if the caller's number can receive texts, so landlines get nothing. And a text reply still needs a person, or a tool, to answer it. If nobody answers the text for three hours, you've only moved the wait from voicemail to text.
The US texting rules you have to follow
Texts sent from software through a regular ten-digit business number fall under A2P 10DLC, the carrier system for application-to-person messaging. Twilio's documentation puts it plainly: anyone sending SMS or MMS over a 10DLC number from an application to the US must register. Registration means telling the carriers who your business is and what kind of messages you send. Unregistered traffic gets filtered and charged extra fees.
Consent matters too. The TCPA and FCC rules govern automated texts, and the carrier industry's CTIA Messaging Principles spell out levels of consent. A reply to someone who texted you first needs no extra permission. Informational texts, like appointment reminders, need the customer's express consent. Marketing texts need express written consent. A missed call is not the same as the caller texting you, so keep the text a short, plain reply about their call, never a promotion, and include a way to opt out. For anything beyond that, ask your phone provider or a lawyer.
Check your missed call setup
- Call your own business line after hours from a cell phone and note exactly what a customer hears and gets.
- Ask your phone provider whether they offer missed call texting and whether your number is registered for A2P 10DLC.
- Write the text yourself: your business name, one line asking what they need, and 'Reply STOP to opt out'.
- Decide who answers text replies during the day and what happens to texts that arrive at night.
Common mistakes
- Turning on texting through an unregistered number, so carriers filter your messages before customers see them.
- Stuffing a promotion or coupon into the missed call text, which turns a simple reply into a marketing message with stricter consent rules.
- Sending the auto text and then leaving the reply unanswered for hours.
How Doug does it
Doug does not answer phone calls or send texts, so he won't text back a missed caller. He covers the other door: customers who find you online. He answers your website chat 24/7 from your own material, takes their details and books them, and you can put your website link in your voicemail greeting so callers have somewhere to book right away.
