3CX Licenses

Setting Businesses Free Since 2005

Save Money

By reducing your current costs by up to 80%

Save Time

With a phone system you can rely on

Save The Day

With a phone system everyone will love

Your phone system shouldn’t be allowed to hold your business back


  • High monthly service costs for every employee

  • Frequent phone system outages and poor quality calls

  • Additional costs for each premium feature you need to use

  • A support service that couldn’t care less about your business

Which leads to unhappy employees, frustrated customers and reduced profits.

It doesn’t need to be that way.

Switch to 3CX with Zen Systems and we’ll guide you to frustration-free telecoms.

We understand

How stressful it feels

Choosing your next phone system, with too many options, confusing jargon, pushy salespeople and the pressure of actually changing systems without any down time – it’s enough to overwhelm anyone!

And it’s not easy to know who to trust if you’ve been burnt by a previous supplier.

At Zen Systems, we know how that feels and we’re here to help. With general advice on getting started with 3CX as a self-managed service, to providing you with a fully managed 3CX service that gves you total peace of mind – whatever you need we’re here for you.

We’re a friendly bunch and it would be great to hear about your phone system needs.
