The business phone system UK teams choose.
Just have the conversation. Olatti brings your calls and team messages together: a business telephone system for UK teams who want to reach someone, say what they need to say and get back to work.
From £5 per user a month, billed annually at £60, or £6 on monthly billing. Calls charged separately on Metered. Prices exclude VAT.
Your business calls, wherever you work.
A business phone system, or business telephone system as it used to be called, gives your team a place to make and receive calls on your business numbers. With a cloud phone system, those calls travel over the internet. Your team can use apps or supported desk phones, without a phone cabinet in the office.
Olatti is built for small teams, typically five to a hundred people, who care about the tools they spend their day using. An agency taking client calls, a consultancy working between home and the office, a software team talking through a decision. The number belongs to the business. The conversation reaches the person.
What changes in your working day.
Keep the conversation together.
Calls, direct messages and channels live in one product. Your call history gives you the number, the person and a way to call back, without copying digits between apps.
Go back to what was said.
Call recording is included on every plan. Plus and Unlimited add call and voicemail transcription and summaries. Recording storage is 1 month on Metered, 12 months on Plus and 3 years on Unlimited.
Use the devices that suit the job.
Desktop and mobile apps are included. A desk phone can still make sense at reception or on a shared desk. Supported handsets are optional; check the hardware range before buying.
A price you can work out before you speak to us.

Move the calls. Keep the number.
Your existing number is already on your website and in your customers' phones. Ask us to check whether it can move to Olatti before you cancel anything with your current provider.
- Check the team, numbers and services you need to move. Include any broadband, alarms or other equipment tied to the old line.
- Set up your users and devices. Test outgoing and incoming calls before moving the number your customers use.
- Agree the porting date once your provider has accepted the request. Keep the old service active until the move is confirmed, then check calls reach the right people.
A new account and an existing number transfer have different timelines. The porting date depends on your number, current provider and the details on the request. We confirm the next steps after checking them.
What to check before you choose.
Work out the whole bill.
Count users, existing numbers and the calls your team makes. Compare monthly and annual commitments. Include call charges, porting and any hardware, rather than comparing the headline price alone.
Try the calls your team actually makes.
Call a colleague, answer a customer and find a previous conversation. Check your required call routing and devices with the provider. A feature list won't tell you how those tasks feel.
Ask where the recordings go.
Check storage periods, access and how recordings are processed. Olatti's voice, transcription and summaries run on We UC's own infrastructure. Read our privacy policy for how we handle data.
Check the move as carefully as the product.
Confirm number eligibility, contract notice, broadband dependencies and the support you need. Our provider comparisons and short answers cover more of the buying questions.
Make the move before the old line goes.
Openreach plans to retire its analogue phone network on 31 January 2027. If your business still relies on an old line, speak to your provider about what needs to change. Openreach explains the move to digital phone lines.
An internet phone service needs a working connection and power. If either fails, calls on the affected devices can stop. Plan how your team will stay reachable, including a separate mobile connection or suitable backup power where needed. Check alarms, payment terminals and other equipment that use the old line before changing it.
Moving a number can also affect broadband supplied on the same line. Ask your existing provider which services are linked before requesting the port. Ofcom's switching guidance explains why the services need to be considered together.
We've been on the other side of the install.
Our founder, Axel Molist, started in telecoms in 2012. He went on to start circle.cloud in 2015, installing and supporting other providers' systems for UK small businesses.
Olatti is the product we built after doing that work. One team building the calls, messages and the software around them, with voice, transcription and summaries running on our own infrastructure.
Choosing a business phone system.
VoIP describes how a call travels over the internet. A business phone system is the service around it: business numbers, users, calling and the tools your team uses to manage conversations. Olatti brings those calls together with team messaging.
Yes. "Business telephone system" is the older name for the same thing, from the years when it meant a physical switchboard wired to desk handsets. The job hasn't changed: give a business its own numbers, ring the right people and keep a record of what was agreed. What changed is where it runs. A cloud business telephone system like Olatti runs as software on the devices your team already carries, so there's no cabinet in a cupboard and no engineer visit to move a desk.
Calls, messages and call history live in one product. A desktop shortcut brings a contact within reach of the work you're already doing. Plus and Unlimited add transcripts and summaries, so you can return to what was said after the call ends.
Metered is £6, Plus is £20 and Unlimited is £25 per user a month on monthly billing. Annual billing works out at £5, £17 and £21 per user a month respectively, paid for the year. Prices exclude VAT. Metered calls and ported numbers are charged separately; allowances and fair use depend on the plan.
Ask us to check your number and provider before cancelling your current service. An accepted port costs £20 per number when raised, then £5 per ported number each month on top of your plan, excluding VAT. Timing and eligibility depend on the number and provider.

Calling on affected devices can stop. Plan an alternative way to stay reachable, such as a separate mobile connection, and assess whether you need backup power. Check any alarms or other equipment using the old line before moving it.
It can provide business calling through apps and supported desk phones. Before replacing an existing system, check the numbers, routing, devices and connected services you need. We can then confirm which parts of your setup can move.
