One less thing to piece together

Set up around your business

Numbers, users, opening hours, call menus and fallback routes start from how your calls actually arrive.

Answer from anywhere

Desk, laptop or mobile: the app is included on every plan, so the business number follows your team.

Managed by people you know

The same Confluxus team that looks after your website and IT configures and supports your phones.

What is a hosted phone system?

A hosted (or cloud) phone system runs your business phone lines over the internet instead of a box in a cupboard or an old copper line. Your numbers, extensions, call menus and voicemail live on a managed platform, and your team makes and takes calls on desk phones, laptops or the mobile app.

For a small business that means no hardware to buy or maintain, a professional caller experience from day one, and a phone system that moves with you — add a user in minutes, answer from home, keep the same number when you change office.

Confluxus sets it up around how your calls actually arrive, then manages and supports it, alongside the website and IT you may already have with us.

Care agencies

Office hours to the team, out of hours to whoever is on call, and no missed call from a family or a carer.

Recruitment

A direct number for every consultant, transfers between desks and queues for the busy Monday morning.

Estate agents

One number across branches, with calls following negotiators out to viewings on the app.

Professional offices

A proper reception, departments callers can choose from, and voicemail that lands in email.

An estimate, not a quote. Desk phones and number transfers are quoted separately. No VAT is added — Confluxus is not VAT registered.

Keep your existing number

Change the phone system, not the number your customers know. Eligible numbers can be moved to Confluxus after checks with your current provider, and your existing line stays active until the switch date is confirmed.

The old landline network is closing

BT plans to retire its traditional copper phone network by 31 January 2027. Business lines, alarms and card machines that still use it need a plan — we can check what you have and move it over in good time.

Questions, answered

Plans start at £7.99 per user per month, with the mobile and desktop app included. Each UK number (DDI) is £2.99 a month. Calls are pay as you go — 2p a minute to UK landlines and 03 numbers, 5p to UK mobiles — or you can add a shared minute bundle. There is a £50 one-off setup fee per business. No VAT is added — Confluxus is not VAT registered.

No long contract. Plans run month to month and you can cancel with 30 days' notice.

In most cases, yes. Eligible numbers can be moved to Confluxus after checks with your current provider. Your existing service stays active until the switch date is confirmed, so calls are not lost in between.

A bundle is one pool of minutes shared by everyone on your account, covering UK landlines, 03 numbers and UK mobiles. It resets each month with no rollover, and anything beyond it is charged at the pay-as-you-go rates. Bundles are the better deal when a good share of your calls go to mobiles; the estimator above works out which option is cheaper for you.

Not necessarily. Every plan includes the softphone app for mobile and desktop, so many teams need no hardware at all. If you want desk phones, we will quote for them separately.

VoIP needs power and an internet connection, so calls — including 999 calls — will not work during a power cut or internet outage unless you have a backup. See the important information below, and tell us if anyone relies on their phone line.

Important information about 999 calls

  • 999 and 112 calls are free and can be made from every phone and app on your Confluxus system.
  • Emergency services are given the address we hold for each of your numbers. Tell us straight away if a phone moves to a different address. Calls made from the app away from that address may not show where you are.
  • VoIP will not work in a power cut or if your internet connection fails, unless you have a backup. Keep a charged mobile phone available.
  • If anyone relies on their landline — for example, they have a telecare alarm or no mobile signal — tell us before you switch and we will provide a free solution so they can still call 999 during a power cut.
