Save The Day
With a phone system everyone will love.
Your business phone system shouldn’t cost ‘that’ much!
With…
-
High monthly service costs for every employee (per seat)
-
Expensive national and international call costs every month
-
Additional costs for each premium feature you need to use
-
And yet more monthly costs for phone line and number rental
And that leads to constantly rising costs as your business grows.
It doesn’t need to be that way.
Switch to 3CX with Zen Systems and we’ll maximise your cost savings.

How many simultaneous calls do you need?
We can work with you to determine what’s best for your business. However, as a general rule of thumb, 1 simultaneous call per 3-4 extensions is sufficient, i.e. a company with 50 extensions would need a 16 sim. call licence.
Is the free licence actually free?
Yes. Annual Standard 3CX licences for 4 or 8 simaltaneous calls are free licence.
That inlcudes unlimited extensions, iOS & Android apps and auto-provisioning.
To make inbound and outbound calls you will need to BYO or choose own SIP trunk and numbers.
You can DIY setup, or set-up and support can be purchased.
Upgrade at any point by paying the price difference and without reinstalling.
What are simultaneous calls?
Simultaneous calls are calls made concurrently at a given time.
Most businesses find they need the ability to make 1 simultaneous calls per 3-4 extensions.
Can I upgrade later?
Yes. You can upgrade your subscription at any point in time by just paying the difference for the remaining period.
What is a 3CX reseller?
A 3CX reseller is company authorised to provide 3CX products. 3CX does not
directly sell its own licences; they must be bought through a 3CX reseller.
We are a Platinum 3CX Partner and have been working with 3CX for 15 years.
Does my licence need to be renewed annually?
Yes. 3CX licences require renewal every year.
Where can I get the 3CX Software?
You can download the latest version of 3CX from the 3CX website. You will find versions for Windows and Linux (Debian) as well as the 3CX SBC. There are also links to download the softphone applictation for Windows, Android and iOS. The aplications are all subject to the 3CX End User Licence Agreement.

The guide covers Installation, creating Users, SIP Trunks, IVR’s/Call centres and System Manangement.

3CX Pricing Guide
3CX pricing is based on the number of simultaneous calls your company needs to make and not the number of extensions or users. This includes internal and external calls. This makes 3CX pricing much more competitive than other phone systems that charge per user.
1 simultaneous call per 3-4 people works best for most businesses. For example, if you have 50 people, you’ll need a 16 SC license. If you’re unsure, buy your license using this ratio and you can easily upgrade it later if needed.
How do I get my license?
Your 3CX license is sent to you via email once your order has completed.
As soon as you place your order, you’ll receive an order confirmation email and we’ll begin processing your order right away. We usually process licence orders within 2 hours.
