How it works
Watch a missed call turn into a booked job.
They ring. You are busy.
Five minutes. You did nothing.
Why a text, and not a call back
You already meant to ring them back.
Everyone does. It is the bit that does not happen — and when it does happen, it arrives as a number they have been trained not to answer.
69% of missed business calls never get a callback within two days
Quo (formerly OpenPhone) — 16.7 million missed calls across their own customers, over three months in 2026.
80% of people block or screen calls from numbers they do not recognise
TransUnion, with Toluna — 1,556 adults surveyed in August 2024, ±2.5% at 95% confidence. 70% said they had missed a genuine call because of it.
So it goes out as a text
Sent within seconds, from your own number, with a link to your booking page. Nothing to answer, nothing to ring back, and it is still sitting there when they come out of the meeting.
Ofcom — The regulator’s Communications Market Report. 92% said the same of phone calls. Person-to-person texting is falling while business-to-person messaging keeps rising.
Not because you do not mean to ring back. Because the minute to do it arrives at nine in the evening, and by then they have booked somebody else.
Being straight with you
What it does not do.
Worth knowing before you buy rather than after. None of it is on a roadmap.
It does not answer the phone
No robot picking up and pretending to be you. It starts after the call is already missed.
It does not chase payment
It can take a deposit and send a receipt. Unpaid invoices are a different job.
It does not replace your judgement
Your slots, your prices, your services. It does not decide what work is worth taking.
The ten minutes
You keep your number. You just tell it where to send the ones you miss.
Nothing is ported, nothing is transferred, and nobody has to learn a new number. You dial three codes into the phone already in your hand, and calls ring you exactly as they do today — Ringback only ever sees the ones that go unanswered.
The last one on the list is how you undo the whole thing, and it is there deliberately. If you can leave in ten seconds without asking us, you are not trapped.
When you do not answer
**61*your Ringback number*11*20#
The one that matters. After twenty seconds of ringing unanswered, the call passes to Ringback and the recovery text follows. Change the 20 for a different ring time — most networks accept 5 to 30 seconds, in fives.
When you are already on a call
**67*your Ringback number#
The second caller does not get a busy tone or your voicemail — they get a text with a booking link while you are still on the first call. On a one-person business this is often the biggest single win of the lot.
When you have no signal
Optional**62*your Ringback number#
Down a cellar, in a loft, phone flat. The network never reaches you, so it passes the call on rather than dropping it.
Turning it all off again
##002#
Cancels every diversion on the handset and puts your phone back exactly as it was. It takes about ten seconds, it needs nothing from us, and it works even if you have cancelled your account and forgotten your password.
One code to avoid: **21*
Do not use this one. It forwards every call immediately without ringing your phone at all, which is not what you want — you want to answer the calls you can and have Ringback catch the rest.
These are the standard GSM codes, dialled on the handset like a phone number, and they work the same way on EE, O2, Vodafone and Three. Some business tariffs restrict diversions — if a code is refused, your network can turn it on.
Worth doing the sums first?
The calculator shows its working, and the one assumption it makes is set deliberately low.
