The phone rings twice under a sink. The caller dials the next listing.
The problem is the thirty seconds after the missed call, when the caller decides whether to leave a voicemail or try someone else. Many try someone else. A text that lands while they're still deciding, asks what they need, and gives them a way to book is what keeps them. Here is what happens, in order.
- 0:00
The call comes in. The number rings your cell for 20 seconds. You're under a sink, so it rings out. The caller hears a short apology that promises a text, instead of a voicemail prompt they'd hang up on anyway. That promise has gaps: after 8 pm, for a caller on a landline, or when the agent hands the thread to you, no text follows. And a caller who hangs up before the apology plays is invisible to the agent: no text, no log entry, just a line in your phone's missed calls.
- 0:20
The caller is screened. Before anything is drafted, the agent drops withheld or malformed caller IDs, your own numbers, premium-rate lines, and calls whose caller ID failed carrier verification. One lookup then drops landlines, toll-free, and fixed-VoIP lines that can't receive a text. Nothing is spent on those.
- Seconds later
The text goes out. The agent checks whether you're open, looks the caller up in your records if you keep any, and writes one short text: an apology, a plain note that it's automated, a question about what they need, and your booking link. A second pass checks it against your configured prices, hours, and links. Then it sends.
- On reply
The thread continues. The caller's answer lands in the same conversation. The agent answers from your FAQ and price list, and moves them toward a booking or a call-back time.
- On handoff
It comes to you. A question it can't answer from your information, or a reply that sounds urgent, gets the caller nothing more from the agent. It comes to you as a Slack alert with a suggested reply you can send, and the caller hears back from you. A caller who wants a person right away can call again or wait for your call.
A sample conversation
What a caller gets when they miss me and this agent picks up the thread: my prices, my terms, my booking link. Yours would carry yours.
The caller hears the spoken line when the call rings out; no voicemail is recorded. The first text names the business, says it's automated, asks what they need, gives one next step, and ends with the opt-out line, all under 300 characters. The agent answers from the caller's reply. Later texts in the thread skip the name and the footer.
Not software you install. Not an app you download.
People search for missed-call text back software or a missed-call text back app and expect something to set up themselves. This is a managed service: the agent runs on my side, the text comes from a number I set up for you, and there is nothing to install. Three other things it gets mistaken for:
It is not an AI receptionist.
A receptionist, human or AI, answers the call. This doesn't. It replies after the call was missed, by text, from the business line I set up for you. If your callers need to talk to someone right now and won't text, buy the receptionist. If they'd rather have the answer in writing and book when it suits them, this is the quieter tool.
It is not a fixed auto-reply.
The missed-call automations bundled with marketing platforms send one message you wrote once to everyone. This one asks what the caller needs, reads the answer, checks your hours, and replies to the actual question. That is the difference between a caller who books and one who wonders if anyone read their message.
It is not a drip.
Nothing is scheduled and nothing is promotional. The agent messages only a number that just called you, only about that call, and it stops when the caller stops. Recurring or marketing texts need a different kind of consent and a different product.
How it's set up, in the order it actually happens.
You keep your number. Unanswered calls forward from it to a toll-free number I provide, or you put the new number on your truck and your site. Everything below runs from one link, and the only real wait is the carrier's.
- 01
Sign and pay through one link. After the call, I create your account and send one onboarding link. It walks you through the terms, the service agreement (your typed name is the signature), and the $850 setup invoice. Nothing is bought or provisioned until that invoice is paid.
- 02
Fill in a short intake. Your website, hours, time zone, service area, services and pricing notes, booking link, how you greet customers, the phrases you always use, the things you must never promise, and who gets urgent problems. Flyers and price lists can be uploaded. You also attest that your customers agree to receive texts.
- 03
I provide the number and file the verification. A toll-free number is provided on its own sub-account, and its carrier verification is filed under your business's own identity. This is the wait: toll-free verification typically clears in about three business days. A local number is available on request, but its registration takes longer.
- 04
Train, then rehearse. I train the agent on your website (up to 25 pages of your own domain) and your intake answers, then run it against its example calls and a few made-up ones and send you the drafts. You tell me which don't sound like you; each correction lands before it goes live.
- 05
Forward your calls, then a test. From your cell, one or two carrier codes, which I send you, forward unanswered calls to the new number. Or advertise the new number directly and skip the forwarding. Then call it from another phone, let it ring out, and read the text that arrives. That test catches the one setting that breaks it: your cell gets exactly 20 seconds of ringing, and if its voicemail answers sooner, the call counts as picked up and no text goes out.
- 06
Live, in shadow mode. For the first weeks I read a copy of every text as it goes out, with the reviewer's verdict, and fix anything that sounds off before it becomes a habit. A wrong price or an off tone gets caught within minutes without slowing any reply down, and each correction becomes a house rule.
After that you get a read-only report link with this month's usage, and a portal for invoices and your card. Conversation records are kept for 90 days. If you leave, the number ports out with you.
It cannot quote a price you didn't give it.
Every draft is written by one model and checked by a second one against your configured prices, hours, terms, and links, plus a set of rules that don't involve a model at all. A draft that fails is corrected once; if it still fails, it goes to a person instead of the caller. For this agent the fixed rule is simple: the first text must name your business and end with the opt-out line. A separate check confirms the same first text says it's automated.
Reply only
The agent may only message someone who contacted you first. For this agent that is the product, not a restriction.
STOP ends it
The carrier blocks the number on a STOP reply, and the agent stops on its own on the same keyword. No later text goes to that number.
Quiet hours
Texts send only between 8 am and 8 pm in your time zone. Outside that window nothing is sent, and nothing is queued for the morning.
No promotion
Advertising language in a reply is blocked. An answer stays an answer, never a solicitation.
Those four are enforced in code on every draft, not requested of the model. The legal footing is that a person who called you first may get a direct reply about that call. It does not cover marketing texts, which need prior written consent you collect yourself. The texting rules are described in Twilio's messaging policy, which the number operates under. Confirm the specifics for your state and trade with your own counsel.
$249 a month. $850 once, first.
$249 a month, plus AI and phone usage, typically $20–40 a month. The $850 setup is the first invoice and covers the number, the verification filing, the training, the rehearsal, and the shadow weeks. Usage is billed monthly on top, as the terms describe. The full terms:
- Month to month, cancel any time
- 30-day cancel for any reason
- No free trial
- Your number ports out with you
- Conversation records kept 90 days
If you'd hand off more than the phones, the 7 paid agents together are $1,200 a month. The pricing page has what costs extra and the market range.
Do the arithmetic before you book the call.
Count last week's voicemails. Say it was eight. If one of those eight would have booked, and your average job is $300, that is $300 a week you didn't invoice, roughly $1,300 a month. At $249 a month, the agent has to recover one job a month to pay for itself. Put your own numbers in. If they don't clear that bar, skip it, and I'll say the same thing on the call.
A fit if…
- You are the one answering the phone, and the phone is also how work comes in
- Ten or more calls a month go to voicemail, and you rarely hear from those callers again
- Your callers are homeowners and individuals on cell phones, not other businesses on desk lines
- You'd rather have the answer in writing and a booking than a call you have to return at 7 pm
Skip it if…
- Someone already answers every call during working hours. There's nothing to recover.
- You miss fewer than ten calls a month. The arithmetic above won't work.
- Your callers won't book by text and need a live voice. That's a receptionist, not this.
- You want it to answer the call itself, take a message, or transfer. It doesn't touch the call.
One more honest note. The proof on this page is the mechanism, not a testimonial: every control above is one I check by hand in the first weeks, when I read every text that goes out. If the job is bigger than the phones, several departments or software of your own, the operations audit is the right door, not this page. If you'd rather see the wording first, the templates page has the texts by trade.
A missed call is one place a lead goes cold. The rest of the chain, from catching every inquiry to knowing when a person should take over, is in how to automate lead follow-up.
