Powered by Gradwell
Get modern telephony for your business, at a fraction of the cost
A powerful phone system for every business
3CX is a VoIP phone system that brings all the benefits of powerful telephony at a fraction of the cost through its simultaneous call license model. Flexible, scalable and feature-rich, it’s a great choice for modern businesses of almost any size. Gradwell is a Titanium level 3CX partner and can provide SIP Trunks that come recommended by 3CX.
Benefits of 3CX
3CX stands out from most VoIP systems with its cost-efficient licensing model, giving you more flexibility and better value. Most platforms charge per user—even if they rarely make calls. 3CX uses simultaneous call licensing, meaning you only pay for the number of calls happening at once, not the number of users. It’s a smart, cost-effective way to scale. Other key benefits of 3CX include…

Frequently asked questions
What’s the difference between a 3CX phone system and my current on site PBX?
3CX is primarily deployed as a cloud managed service in a data centre, rather than as a physical on-site PBX. This removes the risk of any expensive repairs, offers a range of extra features and there is no need for any maintenance contracts. Find out more in our Buyer’s Guide to 3CX.
How is 3CX different to other phone systems?
3CX is an open-source phone system with a user friendly management interface, which can be easily adapted for a diverse set of business needs.
How do I set up additional lines for my business?
Yes! 3CX offers you access a ‘soft phone’ which is an app installed on your mobile phone. This will allow you to access all the features from your office phone and make calls from your office number.
Can I transfer my existing business number to Gradwell?
As long as we have a porting agreement in place with your current provider, we will be able to move over your business numbers. Our experienced team will complete the necessary porting documentation and manage the order through to completion.
Can I get 3CX on my mobile phone?
