The Missed Call: After-Hours and Missed-Call Text-Back Plans
How to plan for busy lines, after-hours calls and missed-call text-back, with the FCC and CTIA texting consent and opt-out rules explained.

For many local service businesses, the phone is still where the most urgent, highest-intent work comes from. Someone with a leaking pipe, a dead furnace or a locked-out car isn't browsing. They are calling down a list, and if your line rings out to a full voicemail box, the next number on that list gets the job.
Missed calls happen for ordinary reasons: you're under a sink, driving between jobs, already on another call, or closed for the night. The goal isn't to answer every call personally. It's to make sure no caller is left wondering whether anyone heard them.
This guide lays out three plans for busy lines, after-hours calls and missed calls, explains how missed-call text-back works, and summarizes the texting consent rules you need to respect. The compliance sections are general information, not legal advice.
Plan 1: The busy line during business hours
When you're open but nobody can pick up, the call should still go somewhere useful. A simple routing plan might look like this:
- Ring the main line for a set number of rings.
- Roll over to a second phone, such as the office manager or the on-duty tech.
- If nobody answers, play a short greeting that says when the caller will hear back, then take a voicemail.
- Put a callback task in front of a named person, with a target time.
Keep the greeting honest and specific. "We're with customers right now. Leave your name, address and what's going on, and we'll call you back within 30 minutes" sets a clear expectation. "Your call is important to us" does not.
Plan 2: After hours
After-hours callers need to know three things: that you're closed, when you'll respond, and what to do if it can't wait. Your after-hours greeting should cover:
- Your regular hours.
- When the caller can expect a call or text back, such as "by 8:30 tomorrow morning."
- Whether you offer emergency service, and how to reach it. If you don't, say so plainly, and tell callers facing immediate danger to contact emergency services.
- A request for the details you'll need to call back prepared.
If you do offer emergency service, decide in advance who is on call, how they're alerted, and what counts as an emergency. A written definition saves a tired technician from making that call at 2 a.m.
Plan 3: Missed-call text-back
Missed-call text-back is an automation that sends a short text to a caller whose call wasn't answered. The idea is simple: a text gives the caller an easy way to reply without leaving a voicemail, and it tells them right away that a real business saw their call.
A good text-back message is short, identifies your business and invites a reply. For example, a fictional plumbing company might send:
"Hi, this is Riverside Plumbing. Sorry we missed your call. How can we help? Reply here, or we'll call you back by 9 a.m. Reply STOP to opt out."
A few practical notes:
- Texts only reach numbers that can receive them, so landline callers still need a voicemail and callback path.
- Route replies to a person, not into an unmonitored inbox. A text-back that invites a reply nobody reads is worse than no text.
- Send one text, not a sequence. The caller contacted you about one problem; your automation should answer that, not start a campaign.
- Log every missed call and text-back so you can see which callers were reached, booked or lost.
The text-back buys you time, but a person still needs to follow up quickly. In the 2011 Harvard Business Review article "The Short Life of Online Sales Leads," firms that tried to reach web leads within an hour were "nearly seven times as likely to qualify the lead" as those that tried even an hour later. The guide "Speed to Lead: How to Respond to New Inquiries in Minutes" covers how to build that habit.
Texting consent: what the rules say
Two sources matter most for business texting in the United States: the FCC's rules at 47 CFR 64.1200, and the CTIA Messaging Principles and Best Practices, which wireless carriers use as industry guidance.
Under 47 CFR 64.1200(a)(1), no one may make a call using an automatic telephone dialing system or an artificial or prerecorded voice to covered numbers, which include cellular telephone numbers, other than for emergency purposes or "with the prior express consent of the called party." For calls that include advertising or constitute telemarketing, paragraph (a)(2) generally requires "prior express written consent." The rule's revocation provisions explicitly cover "calls or text messages."
CTIA's guidelines sort business messages into three categories:
- Conversational: "If the Consumer initiates the conversation and the Non-Consumer simply responds, then no additional permission is expected."
- Informational: "A Consumer needs to agree to receive texts for a specific informational purpose when they give the Non-Consumer their mobile number." Appointment reminders and alerts fall here.
- Promotional: "Before a Non-Consumer sends promotional messages, the Consumer should agree in writing to receive promotional texts."
Note that CTIA's conversational category is described in terms of a consumer texting first. A missed phone call is a different channel, and whether a particular automated text-back requires a specific form of consent depends on facts such as the technology used and the message content. That is a question for qualified counsel. A conservative approach is to keep the text strictly responsive to the call, identify your business, include no promotions or coupons, and offer an opt-out. CTIA also warns that adding a call-to-action, such as a coupon code, to an informational text "may place the message in the promotional category."
CTIA also notes that carriers and other service providers may apply their own protections, including "campaign pre-approval, Service Provider vetting, in-market audits, or Unwanted Message filtering," so expect your texting provider to ask how you collect consent.
Honor opt-outs quickly and completely
The FCC rule says a person may revoke consent "by using any reasonable method," and that replying with "stop," "quit," "end," "revoke," "opt out," "cancel," or "unsubscribe" is a reasonable method by definition. Replies using other words must be treated as revocation "if a reasonable person would understand those words to have conveyed a request to revoke consent." Revocation requests must be honored "within a reasonable time not to exceed ten business days."
You may send one confirmation text after an opt-out, as long as it "merely confirms the text recipient's revocation request and does not include any marketing or promotional information." The rule presumes a confirmation sent within five minutes falls within the consumer's prior consent.
CTIA adds that opt-outs should work through "phone call, email, or text," and that minor variations such as capitalization or punctuation shouldn't invalidate a request.
Keep records
CTIA recommends documenting consent with details such as the "Timestamp of consent acquisition," the medium used, the "Specific campaign for which the opt-in was provided," and the phone number that consented. For a missed-call program, that means keeping a log of the inbound call, the text you sent, the replies you received and any opt-outs. Good records protect you and make it easy to show a carrier or customer exactly what happened.
Key takeaways
- Build separate plans for a busy line, after-hours calls and missed calls, each with a named owner and a callback target.
- After-hours greetings should state your hours, when you'll respond and how emergencies are handled.
- Missed-call text-back works best as one short, clearly identified, non-promotional message routed to a person.
- The FCC's 47 CFR 64.1200 and CTIA's Messaging Principles set the consent framework; promotional texts call for written consent.
- Honor opt-outs such as "stop" promptly, within ten business days at most, and keep consent and opt-out records.
