The world has moved on.

Gone are the days of telephony as an isolated channel for voice alone. With a powerful new software-based switch it is at last integrated to IT systems. This makes it possible to think about internal communications and customer communications in the round.

All of which means more flexibility to improve your customer and staff interactions, easier management, and new opportunities for CRM and service innovation.


Zen Systems use 3CX, a breakthrough software phone system that operates over IP networks to handle calls to and from your business – replacing inflexible conventional telephone switches, and reducing the costs of calling.

It saves you a lot on conventional telephony charges, and it supports an array of technologies that make business easier, such as web conferencing, presence, soft phones, and smartphone clients.

A PBX that cuts call costs

Traditional PBXs are difficult to scale. Add more extensions and you are hit by licensing costs, underpowered hardware or you run out of ports. Cloud PBXs are one solution, but many lock you into expensive per extension and per minute pricing… Not so with 3CX.

Moreover, remote workers or employees on the go can call for free. Connect remote offices, improve communication, and make interoffice phone calls free. International DIDs and IP Telephony mean customers can call you cheaply too.

Integrated features for business productivity


3CX’s integrated web conferencing, WebMeeting, saves on third party conferencing subscriptions while more reliable and feature-rich than mass market providers.


Being able to see if colleagues are available or not is a great time saver. Avoiding unnecessary call transfers or ‘voice mail tag’, it makes managing and working with remote employees easier than ever. If you need some privacy, you can also set your own status to reduce annoying interruptions.

Instant messaging

Text chat, without the need to rely on third party internet messaging systems is a productivity advantage especially good for regulated businesses where it is vital that communications are ring-fenced. 3CX users can send and receive text messages via the 3CX Windows, Mac, iOS and Android clients from anywhere.

Voicemail and fax to email

Inbound faxes are converted to PDF and forwarded to users via e-mail, without requiring any fax server software. Likewise voicemails are converted to sound files and forwarded via e-mail.

Switching to 3CX is easy. Whether in the cloud or on site, we simplify the process.
Following a site visit and ongoing needs analysis we work out a plan with you, then design the system to meet those needs, agreeing the optimum solution for your business.
With complete visibility and clear monthly pricing as a managed 3CX host, Zen’s telecoms service is beautifully simple.
Install 3CX on site or in the cloud

3CX will run on an existing server using Hyper V or VMware, or equally easily on a cloud-based server with built-in backup and restore. Smaller installations can run on a low-cost, dedicated PBX appliance.

Whether in the cloud or on site, you’re in control. There are no long term contracts, and no per extension licensing. Self-host on popular cloud providers offering standard Linux VPS, or outsource to a managed 3CX hosting partner.

Take your office extension with you

With the 3CX VoIP clients for Android and iOS you can take your extension wherever you go. Now you only need publish one number, (you no longer need give out your mobile number). Set your status so your colleagues can see whether or not you are available to take a call.

3CX features native Android and iOS VoIP clients with an inbuilt tunnel to avoid remote firewall issues – calling from over 3G or from any Wifi hotspot is extremely reliable. 3CX Android and iOS clients fully support PUSH, allowing the phone to be on standby and save battery life.

Powerful, easy to use softphones for Windows and Mac included

With integrated clients for Mac and Windows, 3CX lets you manage your phone calls, whether in the office using CTI and your desk phone, or on the road using your laptop.

With 3CX’s softphones for Mac and Windows you can manage calls from you desktop and make and receive calls via the office phone system from your computer, even while out of the office.

Using a headset, your 3CX client becomes a full desk phone replacement.

Manage your calls with the 3CX switchboard – Integrates with Office 365, Google, or Outlook

3CX includes a powerful switchboard function that can be tailored to the way you want to view and manage your phone calls. With five different views to choose from, it adapts to any job role.

You can launch calls directly from your CRM package. Inbound calls are matched to customers based on the caller ID and logged in your CRM system. Keeping track of inbound and outbound calls with call durations allows you to generate insights on customer and agent activities.

Hassle-free conferencing with WebRTc

3CX harnesses Google’s revolutionary WebRTc technology, which puts video and voice communications in the internet browser – participants join meetings without having to download any additional software or plug-ins.

3CX’s integrated video conferencing can easily be launched through the 3CX client with a few mouse-clicks. With 3CX there’s no monthly subscription fee for each user and no peripheral hardware required.

There’s no need to login anywhere, so it’s incredibly easy to setup meetings. Upload your PowerPoint and PDF files for crisp, responsive delivery – take comments then use the simple polling tool for approvals.
