The £50,000 call went to voicemail.

Your number, your mobile, your WhatsApp
Voxra isn't an app you forward calls to. It's built into IQ Mobile's UK mobile network, so Voxra answers on the line itself.
Your business number, on your mobile
Pro and Complete include an IQ Mobile eSIM, so your business mobile lives on our network: your mobile rings first, and if you are busy Voxra catches the rest. No call-forwarding apps to set up. Line rings the mobile you already have. Start with a new local number today, or bring your existing one across.
It knows you missed the call
Because Voxra runs the line, it picks up when you don't. Urgent calls come straight through to your mobile, and everything else lands as a summary in the Voxra app.
The Voxra app, and WhatsApp
Every call, recording and booking is in the Voxra app. Customers can WhatsApp you and Voxra replies, and you run the day by messaging it: “what did I miss?”, “book Mrs Patel Tuesday 10am”, “send the quote to Chris Moore”.
One UK bill
Number, mobile and AI receptionist on one monthly bill in pounds from IQ Mobile. No contract, cancel any time.
Built for building work
Voxra knows a loft conversion from a wall that's come down.
Extensions
Single or double storey, kitchen or rear. Size, plans and planning captured, then a site visit booked.
Loft and garage conversions
The house, what they want the space for and whether there are drawings, taken down for you.
Renovations and new builds
Bigger projects get the details and a meeting in your diary, so the serious enquiries reach you first.
Repairs and small works
Walls, patios, chimneys and damp. Quick jobs that fill the gaps between projects.
Urgent call-outs
Storm damage or a wall down? It flags it as urgent and offers to put the caller through to you.
Quotes
Voxra drafts a written quote from the call for you to check, and one tap sends it.

Why do Pro and Complete include an eSIM?
Voxra isn't an app you forward calls to. The eSIM puts your phone on Voxra's own line, so Voxra is built into both your mobile and your business landline number.
- It answers your mobile when you can'tCalls to your business number and your Voxra mobile number ring your mobile first. If you don't pick up (up a ladder, driving, on another call), Voxra answers in your business name. No call-forwarding codes to set up, and nothing to redo when you change handset.
- It listens to the calls you take yourselfVoxra records the calls you answer on your business number and Voxra mobile, and picks out the follow-ups as drafts for you to check: quotes to send, jobs to book, new contacts to save. Callers hear that the call may be recorded before you're connected, and you can switch it off in Settings.
- Your personal number stays yoursThe eSIM sits alongside your existing SIM on the same phone, with calls, texts and 3GB of data, all on one Voxra bill. Most phones from the last few years support it.
Voxra Line doesn't include an eSIM: it rings the mobile you already have, and if you don't pick up in 25 seconds, Voxra answers.

Questions
What is an answering service for builders?
An answering service for builders answers enquiries while you're on site. Voxra is an AI receptionist on your own UK number: it finds out what the caller wants built, gets photos on WhatsApp, books a site visit into your diary and puts urgent calls through to you.
Do I keep my number?
Yes. You get a new local number straight away so you can start today, and we'll help you move your existing number across. It then lives on the Voxra eSIM that comes with Pro, so it still rings your mobile first.
Can it tell a big project from a small job?
Yes. You tell Voxra what work you take on. It asks about the size of the job, plans, planning permission and timing, books the ones you want into your diary, and anything outside what you do comes to you as a message.
Will it give prices?
Only the ones you give it, such as a charge for a site visit. Building work needs a look first, so it never makes up a figure: it books the visit instead.
I get leads from MyBuilder and Checkatrade. Does it work with them?
Yes. Directory leads ring your number like any other call, so Voxra answers them. You stop paying for leads that go to voicemail.
What if I run out of minutes in a busy month?
Add a bundle any time: 250 minutes for £25, 500 for £50. If you don't, AI answering pauses until next month and calls go to your mobile and voicemail. There's never a surprise bill.
Will callers know it's AI?
Yes. Voxra says it's your AI assistant. That's the honest thing to do, and our terms require it. It sounds natural, and most people just want someone to come and look at the job. Anything it can't handle comes to you.
Why does Voxra come with an eSIM?
Because Voxra runs your mobile line itself, it can answer your mobile when you can't: calls to your business number and your Voxra mobile number ring your mobile first, and Voxra picks up the ones you miss, with no call-forwarding to set up. It also records the calls you take yourself and picks out follow-ups such as quotes to send and contacts to save (callers are told first, and you can switch it off). The eSIM sits alongside your existing SIM, so your personal number stays as it is.
How does the free trial work?
You get 7 days free from the moment your Voxra number goes live. Once you have your number we'll ask for a card or Direct Debit, but nothing is taken until the trial ends. Cancel before then and you pay nothing.
Is there a contract?
No. Monthly plans roll month to month and you can cancel any time. Pay annually and you get two months free. All prices exclude VAT.
