There are so many different types of business telephone system on the market today, and 3CX is one of them.
A new telephone system is an essential investment for any business—and understanding what your signing up for is important. Our guide is here to help you get a clear picture of what 3CX actually is, and how your business might benefit from 3CX.
What is 3CX?
If you’re in the market to upgrade your businesses phone system, then you have probably come across the name 3CX.
3CX is a brand of software-based business telephone systems. 3CX allows your business to make and receive telephone calls using a technology known as VoIP (Voice over IP).
‘Traditional’ PBX (telephone system) equipment uses physical, on-site hardware to control your businesses telephone calls. This hardware is clunky, outdated and expensive to purchase and maintain—and as such is being swiftly replaced by software based telephone systems such as 3CX.
3CX uses a licence-based model, which means that you’re only paying for the number of licences you’ll actually need. The licence you choose will depend on the number of concurrent calls your business requires, and more licences can be added as your business grows.
How does 3CX Work?
As we mentioned, 3CX uses a technology called VoIP to carry your businesses telephone calls. VoIP calls travel over your businesses broadband connection, rather than traditional ISDN telephone lines.
This makes better use of your existing broadband connection, and eliminates the requirement for multiple telephone lines, as the costs associated with these lines.
3CX phone systems use something called SIP Trunks. It is these SIP trunks that turn your broadband connection into a phone line, by running onto of your line and allowing calls to pass through unimpeded by data traffic.
Each 3CX telephone system needs SIP Trunks to carry their calls. The more SIP trunks your business has, the more calls you can carry.
In terms of physical hardware, 3CX supports a huge range of existing deksphones and DECT phones. This means that you can pick and choose the phones that best suit your business, whether you need wireless handsets for a warehouse, or touch screen desk phones for your office team.
Types of 3CX Deployment
Part of what makes 3CX telephone systems so versatile is the flexibility in their deployment. In fact, there are three different types of deployment for 3CX phone systems—each with their own benefits.
1. Cloud Hosted
Hosted deployment, often referred to as a ‘hosted PBX’ is a fully cloud-based deployment of 3CX. With little-to-no physical hardware required at your office or premises, cloud deployment is often the chosen route for many businesses, particularly small and SME size companies.
Low rollout cost
No maintenance required
Less reliable than on-premise
2. On Premise
On premise 3CX systems use your businesses IT hardware to host your telephone system, this is typically a dedicated PC or a server. By hosting your 3CX system on premise, you can increase the reliability of your solution, and make use of your existing infrastructure, rather than paying hosting fees.
However, on-premise solutions are often more difficult to implement as they require hardware and equipment at your site. Typically, an on-premise 3CX rollout is the best option for larger businesses with 60+ extensions. But every business is different.
More security options
By far the most reliable and robust option for a 3CX implementation is a hybrid setup. This combines both on-premise and cloud hosted 3CX setups. With a hybrid 3CX, your business has the reliability and robust-ness of an on-premise 3CX, but with the backup and failover of a cloud solution.
This is normally reserved for large or enterprise level businesses with service-critical reliance on telephony, such as business call centres, 999 handlers or telesales setups. A hybrid setup does require more management and setup than it’s alternatives, but offers the most reliable telephony possible.
Increased management required
