Zen Systems · 3CX Titanium Partner
Fully managed hosted 3CX
One monthly payment for hosting, a 3CX Pro licence, SIP channels and UK support. We build the system, move your numbers across and look after it for as long as you're with us.
Why fully managed
Why we think fully managed is the right choice for most businesses
3CX works the same whichever way you run it. The difference is who keeps it running, and who you call when something goes wrong. For most businesses that depend on their phones, handing both of those to us is the safer call.
Buying just a licence
A 3CX licence on its own won't make a single call
The licence is only the software. You'd still need to find somewhere to host it, then a SIP trunk provider to connect your calls, and then someone to set it all up and keep it running. That's three suppliers to choose, pay and chase when something goes wrong. Fully managed brings all of it together with us.
One supplier, one monthly payment
Nobody in your office has to become the phone system expert
On your own server, someone has to install updates, check the backups and fix things when they break. It usually lands on whoever knows most about IT, on top of their actual job. With fully managed, that's our job.
The people who built your system are the ones who answer
When you call us, the engineer already knows how your extensions, queues and call routing are set up, because we set them up. You don't have to explain your system from scratch while a customer waits.
A hardware fault doesn't take your phones down
Every fully managed plan runs across two physical hosts on our Equinix London private cloud. If one fails, your calls carry on from the other, without anyone in your office needing to do anything.
You know what it costs every month
Hosting, the Pro licence, SIP channels and support come in one monthly payment, and UK calls are included on a 36-month term. There's no separate call contract to manage and no charge each time you need help.
When it might not be the right fit
If you have your own IT team who want full control of the server, running 3CX yourself may suit you better. We'll tell you that honestly, and we can still supply your licence.
What fully managed means
We run the phone system, and you get on with running the business
With fully managed hosting, your 3CX system lives on our private cloud rather than a server in your office, and we're responsible for keeping it running. That covers the hosting, the updates and the day-to-day admin, as well as the support when someone needs help.
Because we built your system, we already know how it's set up when you call. If a new starter needs an extension or your opening hours change, you tell us and we make the change.
What we look after
- Hosting on our Equinix London private cloud, with a 99.99% uptime SLA
- 3CX updates and backups, plus 24/7 platform monitoring
- Setting up extensions, call queues and the "press 1 for sales" menu
- SIP channels, and moving your existing numbers across
- UK support, 9am to 5:30pm Monday to Friday
What's left for you
Letting us know when your team or call routing changes, and one monthly Direct Debit.
Plans
Tell us the size of system you need and we'll send your price
Plans are sized on simultaneous calls (how many calls can happen at the same time) rather than per user. If you have 40 staff but rarely more than 12 on the phone together, Medium would usually be enough. Get in touch, tell us your team size, and we'll confirm the right plan and send you a price.

Getting you live
What happens between choosing a plan and your first call
The switch is the part most people worry about, so we keep it in an order you can follow. Your old phones keep working until the new system has been built and tested.
-
01
You tell us what you need
Request a quote with your team size and how you take calls. We confirm the right plan and send you a price.
-
02
You approve and set up payment
Once you're happy, you pay the one-off setup fee and complete a Direct Debit for the monthly payment.
-
03
You tell us how you take calls
Fill in the onboarding form: who needs an extension, which numbers you have and where calls should go. It saves as you go.
-
04
We build, test and move your numbers
We set up and test the system, then bring your numbers across at a time agreed with you.
Set up for you
Because we manage it, your team gets the parts of 3CX that usually go unused
Every fully managed plan includes the 3CX Pro licence. On a system you run yourself, features like these often stay switched off because nobody has time to configure them. With fully managed, we set them up around how your business takes calls, and change them when you ask.
Your desk phone on your laptop and mobile
We set up the 3CX apps for each person, so staff can take calls on their business number from a computer or mobile and callers never know they are away from the office.
Seeing who is free before you transfer
Each person's status shows in the app, so a call goes to someone who can actually take it instead of ringing out at an empty desk.
Call queues and a "press 1" menu
We build the menu and queues from your onboarding form, so callers reach the right team and wait for the next free person. When your teams change, we change the routing.
Call recording, stored for you
Calls can be recorded for training or disputes, and we look after the storage on our servers, from 5GB on Micro to 60GB on Enterprise. There is no disk space for you to watch.
Links to the software you already use
We can connect 3CX to Microsoft 365, Google Workspace or your CRM, so the caller's details appear before you answer, without your team working out the integration.
Video meetings on the same system
Staff can start a video call from the same app they use for phone calls, so meetings and calls sit in one place.
Questions
What people ask before signing up
Why choose fully managed instead of hosting 3CX myself?
Running 3CX yourself means someone in your business owns the server, the updates, the backups and every change to how calls are routed. With fully managed, we do all of that, the system runs across two physical hosts so a hardware fault doesn't take your phones down, and the people who answer your support calls already know your setup. You pay one monthly amount instead of arranging hosting, calls and support separately.
What's included in fully managed 3CX?
We host and administer your 3CX system on our private cloud. The monthly payment includes a Pro licence, SIP channels (the connection that carries your calls over the internet), backups, call recording storage and UK support. On a 36-month term it also includes calls to UK local, national and mobile numbers.
How is it paid for?
A one-off setup fee, then one monthly Direct Debit. We'll confirm both in your quote, so you know exactly what you'll pay before anything is built.
How do I choose the right plan size?
Think about your busiest hour rather than your headcount. Plans run from 4 to 32 simultaneous calls, and if your team spends most of the day on the phone, the next size up may suit you better. Anything above 32 is a custom quote. Tell us how your team works and we'll recommend the right size.
What happens once I agree a quote?
We email a welcome pack with your login, the Direct Debit mandate and a link to the onboarding form. Once that's complete, we can start building your system.
Can I keep my existing phone numbers?
Yes. Moving your numbers to a new provider is called number porting, and we handle it as part of the setup. List your numbers on the onboarding form and we'll take it from there.
About Zen Systems
We've spent 18+ years looking after 3CX for UK businesses
We're a 3CX Titanium Partner, and 3CX phone systems are what we know best. Over that time we've seen what happens to the system after it's switched on, and that's where most hosting falls short.
Run 3CX on your own server and someone in your business has to keep it updated, backed up and working. Basic hosting takes the server off your hands, but the setup, the calls and the support are still yours to sort out, often paid for one ticket at a time. Fully managed is how we close that gap: we host it, run it and support it, so there's one team responsible for your phones.
