The problem
A missed call is not a delayed sale. It is a lost one.
When someone rings a local business, they're usually near the end of their decision, not the start:
- They've already searched and shortlisted. They're working down a list, and the first business that picks up is heavily favoured.
- The ones that ring out don't get a second attempt. There's no reason to try you twice when the next number is right there.
- Voicemail asks the caller to do the effort. Listen to a greeting, compose a message, then wait an unknown length of time for a stranger to ring back. Most won't, and there's nothing irrational about that.
You end up with a gap of hours between the moment someone wanted to hire you and the moment you find out they called. Missed call text back exists to close the front end of that gap: get something in front of the caller within thirty seconds, while they're still deciding.
How it works
A call goes unanswered – you're on a job, on another call, or outside hours. The system detects it and fires a pre-written text to the caller's mobile. The message appears to come from your business.
Most implementations use one of three routes:
- Business phone systems. Many VoIP providers (RingCentral, 8x8, and similar) include missed call SMS as a feature.
- CRM or automation tools. Platforms like GoHighLevel can trigger an SMS from a missed call event.
- Dedicated missed call text back services. UK providers such as those at missedcall.boldstudio.uk and mctb.1nexus.co.uk offer standalone tools built around this single function.
Setup is straightforward: connect your business number, write your message, enable the trigger. Most configurations take under an hour.
SMS templates for trade businesses
Good missed call texts are short (under 160 characters), acknowledge the call, and give the caller a clear next step. One question is enough.
Plumber
Hi, it's [Your Name] at [Business]. Sorry I missed you – I'm out on a job. Is this about a new callout or an existing booking? I'll ring back soon.
Electrician
Hi, [Business Name] here. Missed your call – I'm on-site right now. Text me what you need and I'll call you back as soon as I'm free.
Builder / general contractor
Hi, it's [Name] from [Business]. Missed your call but I'll get back to you. Can you drop me a note on what the job is? Helps me come prepared.
Emergency callout (plumber/electrician)
Hi, [Business]. Sorry to miss you. If this is an emergency, please call [backup number or 999 if relevant]. Otherwise I'll ring back within the hour.
After-hours (generic)
Hi, [Business Name] here. We're closed right now but saw your call. We're back at [time]. Text us what you need and we'll pick it up first thing.
Customisation tips
- Use your actual first name, not just a business name. It feels personal.
- Say you're on a job. Callers forgive a missed call when they know why.
- If you have a booking link, add it: "Book a time here: [link]." Lets the caller act without waiting.
- Keep it under 160 characters to avoid multi-part messages on some networks.
When text back beats voicemail
Voicemail has a fundamental problem: roughly 70% of callers won't leave a message. They ring off and move on – often to the next result on Google. A text that arrives within 30 seconds changes that. The caller has already moved on mentally, but the message catches them before they book elsewhere.
Text back is better than voicemail in most trade scenarios because:
- It reaches the caller on a channel they actually check. SMS open rates are high.
- It doesn't require the caller to do anything. No number to dial, no greeting to sit through.
- It starts a conversation rather than ending one.
- It buys you time. The caller knows you know they rang. They'll usually wait for a reply before calling someone else.
What text back cannot do
Text back is genuinely useful. It also has real limits.
It cannot answer questions. If a caller wants to know whether you cover their postcode, what your call-out charge is, or how quickly you can attend, a text message cannot help them. They wait for you to call back.
It cannot qualify the job. You still don't know whether the call is a good lead or a time-waster until you ring back. That's time spent on calls that may not convert.
It cannot book a job. A text can include a booking link, but the caller still has to click it, choose a slot, and complete the booking. Dropout at each step is significant.
It relies on the caller being on a mobile. Landline callers cannot receive SMS at all, so those enquiries fall through the gap entirely. If you take a meaningful share of calls from offices, letting agents, or older customers, text back covers less than it appears to.
It is not a conversation. Text back is a one-way nudge. If the caller replies with a question, someone – or something – has to handle it. Which brings you back to the same problem.
For a trade business with consistent inbound enquiries, text back is a meaningful upgrade over voicemail or silence. It is not a replacement for answered calls. A call that is actually answered – where the job is qualified, the details taken, and a next step confirmed – is worth considerably more than a text that says "sorry I missed you."
An AI receptionist fills that gap. The call is answered, the job details captured, and the caller leaves with a clear next step. No callback required for the first pass.
Telphi
Telphi answers your calls rather than reacting after they go unanswered. When a caller rings, Telphi picks up, qualifies the job, captures the details, and can text the caller a booking link so they go straight into your calendar – all before you even know the phone rang. You get a structured summary when you come off the job.

Frequently asked questions
Replying to someone who called your business number is fine under UK law. It is a response to an inbound contact, not a marketing broadcast. You do not need prior consent for the reply itself. Sending unsolicited marketing texts to numbers harvested elsewhere is a different matter and requires consent.
Most systems send within 30 seconds of the missed call being detected. Some are near-instant; a few take a minute or two depending on the platform.
Some services route through your number directly; others send from a business landline or virtual number. Check with the provider. If the reply comes from a different number, some callers find it confusing.
SMS cannot be delivered to a landline. The call will still be missed and no text will arrive. For businesses that receive a significant proportion of calls from landlines, text back covers fewer gaps than it appears to.
Yes, and it is worth doing. A link to a booking page, calendar, or contact form gives the caller an immediate action. Keep the text short enough to accommodate the link without going over 160 characters.
Yes – it triggers on any missed call at any time. Evening and weekend callers get an immediate response rather than silence.
Standalone services range from free (included in some phone systems or CRMs) to around £10–£30/month for dedicated tools. Per-SMS costs may apply on some platforms. ---
