3CX phone system case studies

6 reasons your business should be using a 3CX phone system

Like every other phone system provider you will meet, we have a preferred VoIP PBX (in our case 3CX) that we recommend to our clients. However unlike most of our competitors, we intentionally took the decision to pick a phone system that is actively disrupting our industry – this is why…


1. Compatibility

Since 3CX only do software, they have made 3CX hardware agnostic. This means that 3CX can work with nearly all modern VoIP handsets, gateways and other SIP standards based hardware.

2. Rapid feature development and release

As a software only product, all of 3CX’s engineering resource is focused on new feature development, and since it’s just another windows application, it can be upgraded quickly and easily.

3. Really easy to manage

Use the included web management interface to manage your phone system from anywhere. 3CX can auto provision handsets from most major vendors making the deployment of 3CX (and subsequent extension configuration, additions and moves) really easy.


4. It’s just another application

Use existing Windows or Linux servers, and management tools to manage your phone system, making backups and restores of your business communications as easy to perform as any other application on your network.

5. Use VoIP/SIP trunks from any provider

Since 3CX supports the industry standard SIP protocol, it can connect to all major SIP trunk providers. Grapevine can help you migrate your existing landline numbers to SIP releasing your numbers from a physical line into your premises providing you with the ability to get your phones back up and running fast in the event of a disaster or loss of service.


6. Unified Communications Ready

3CX has been built from the ground up to support Unified communications, with mobile presence, a dedicated smartphone app for making and receiving calls and incoming fax and voice mail to email.

3CX Phone Systems Frequently Asked Questions

How does a 3CX phone system work?
3CX is a software based VoIP telephone system. That means that it runs on a server (hosted by us or in the public cloud), a desktop PC or even a Raspberry Pi. Gone are the days of the physical telephone system being hung on the wall in your comms room or under a desk. VoIP stands for Voice Over Internet Protocol. This means that your calls will use the internet to route through instead of traditional fixed lines such as PSTN or ISDN.
What phones/handsets work with 3CX?
The great thing about 3CX Phone System is that works with many different brands of IP based phones, including Fanvil, Snom, Yealink, Grandstream & Gigaset. This means that you could utilise your existing hardware to simply connect to your new 3CX phone system hence reducing on costs.
How much does 3CX cost?
3CX is very different to many other VoIP telephone systems in that it is licensed based on the number of simultaneous calls the system will allow you to make.
A simultaneous call could be an internal conversation between two extensions on the system, or it could be a customer/client calling and speaking to your team. Therefore, you could have 1,000 extensions connected to the system, but only require a much smaller simultaneous call license. Licenses come in 3 different levels; Standard, Professional & Enterprise. Within each level, you can then choose your number of simultaneous calls required ranging from 4 all the way up to 1024.

What is 3CX?
Founded in 2005, when VOIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications. Taking advantage of the SIP open-standard and WebRTC technology, 3CX has evolved from its roots as a PBX phone system to a complete communications platform, offering customers a simple, flexible, and affordable solution to call, video and live chat. With 3CX, businesses can increase productivity and enhance customer experiences, whilst dramatically cutting costs and management headaches.
What are the benefits of 3CX?
Can your employees work productively from anywhere using voice apps on their smartphones? Conduct remote business meetings via web conferencing without requiring apps? Service customer requests via website live chat? With 3CX Phone System they can do this and much more. The freedom of choice doesn’t end there, with 3CX you can choose to deploy on-premise on Windows or Linux, in your private cloud account or opt for Grapevine Connect to host your PBX for you. Whatever your preference, you are guaranteed a hassle-free PBX that requires minimum management.
What is a VoIP call?
VoIP stands for Voice Over Internet Protocol. This means that your calls will use the internet to route through, instead of traditional fixed lines such as PSTN or ISDN.
What is the difference between PBX and IP PBX?
An IP PBX is Internet Protocol based, and therefore is software that runs on a generic server or computer. A traditional PBX is a proprietary device that manufacturers produce.  (It was generally that black box on the wall that nobody knew how it worked or what it did.) Generally with a traditional PBX, you would have to purchase the same brand telephone hardware to connect to the telephone system. An IP PBX is so much more flexible! It allows deployment in the cloud which helps reduce capital set up costs, disaster recovery and facilitates simple remote working. 
How do you set up 3CX?
There are many different ways you can set up a 3CX, but in the first instance you have to ask yourself the question; do I want to install this in our office environment on a server etc…or, do I want to deploy this in the cloud? Your answer to that question will then lead you onwards. If you install on site, there are factors to consider including firewall management and what hardware specification you require to run your system. If you install in the cloud you have similar questions, but why don’t you contact us and we will help you through the decision making process.
How is 3CX difference from other systems?
3CX disrupted the PBX market when it introduced its innovative licensing model. For example, other hosted systems will charge a per handset(or user)/per month fee. Imagine you have a school with 50 telephone handsets. Most of those handsets are in classrooms where the handset could be used once a week at most. You then have a small proportion of handsets in the administration offices which will make the bulk of the call traffic. Now, in the per handset/per month model, you would be paying for handsets that are very rarely used. Now think about the 3CX model, you could have 50 handsets connected to the system, but only need an 8 simultaneous call license costing £276 annually to cover everything you need!
How is 3CX hosted?
There are many different options if you want to have your 3CX hosted, ranging from Google, Azure, Amazon Cloud or directly with Grapevine Connect in our bespoke, tailor made environment that has 3CX at its core.
Who is 3CX for?
Everyone! 3CX has been selected by world leading companies to meet their Unified Communications and telephony requirements. These range from the likes of American Express, McDonalds, NHS, Holiday Inn & Air France. But 3CX is not just for giant corporations, it also fits perfectly for smaller companies with just a few employees.
How can 3CX help my business?
Too many ways to number but here is a brief list: enabling seamless remote working anywhere in the world, free iOS & Android apps, free video conferencing, live chat plugins for your website, Microsoft 365 integration, Facebook messaging, sending business text messages and most importantly, cutting your telco costs by up to 80%.
