3CX: Best for – Unbeatable Pricing

3CX is an open-source PBX (Private Branch Exchange) contact centre service with more than 250,000 customers worldwide. Because it’s an open platform, users aren’t required to choose from a specific host and SIP trunk as well as an IP phone and phone number. Instead, you can choose your own Unified Communications (UC) platform such as MS Teams to integrate with. You also have the choice whether to deploy the phone system on premise or hosted in your own cloud. Services like Horizon can host using a desktop client as a softphone by simply adding a headset. This greatly reduces costs for the business as they don’t need to buy expensive phone equipment.

Pricing: £276 to £365 per user per year


Unified Communications

You can either integrate with your current UC platform or use 3CX’s unified communications at no additional charge. This omnichannel service includes video, SMS, Webchat and FB Messenger.

Vonage Business: Best for – User Specific Features and Customisations

Vonage’s beginnings started with a focus on the residential sales of VoIP as they strived to push it into the mainline. This has enabled their features to be fully customisable, making it ideal for companies that want user-specific VoIP features. This allows companies to use cloud-based VoIP features that help employees to be more productive when it comes to meetings and staying in contact with customers.

Pricing: £276 to £365 per user per year

With a wider range of features, as well as being cheaper, 3CX beats Vonage in most of the areas discussed here but you will have to remember it’s an open-source platform that will need to be hosted and supported.

Choosing your own end-points such as phones and headsets can be seen as benefit or a curse but does allow more variety and pricing points for users. 3CX is a very affordable and dynamic phone system, suitable for a heavy call volume and for remote work. You can either set it up yourself or use a dedicated I.T provider with experience in setting up a PBX contact centre.

However, if you are looking for more of an out of the box solution then Vonage may suit you more, especially with the user-specific customisations it has to offer. Other out-of-the-box solutions are discussed in our RingCentral vs. 8×8 battle.
