3CX Helps UK Company Achieve Business Goals to Expand with Mobility

NANT Ltd. gives up expensive and restrictive PBX for scalable 3CX Phone System for Windows and sees immediate staff mobility benefits


NANT LTD ( is a water risk assessment company specialised in the detection, elimination and prevention of Legionella. Established since 1994 and with over 1000 clients all over the UK, they have a busy and growing operation that includes several home workers as part of their permanent staff. They were stuck with a traditional hardware-based proprietary PBX that was restricting employee’s mobility, until their Network Manager decided to deploy 3CX Phone System for Windows. This move has brought mobility to NANT’s staff and significant cost savings to the business.

NANT_WATER1David Buckley runs RAPIDTECH LTD (, which is a software development solutions provider and sister company of NANT Ltd. David is NANT’s Network Manager and the person responsible for the installation and management of 3CX IP PBX at the water treatment company, “Home-working is very important for NANT’s operation: from administration staff who take care of general duties, to the risk assessment team who performs the on-site Legionella risk assessments and all associated paper work that needs to be completed to create the logbook that is presented to each client. Also, management staff works from home on days that they are unable to get into the office. All home users are permanent members of staff and, although numbers vary on a day to day basis, it generally tends to be five members of staff working from home on any given day.”

Before 3CX IP PBX for Windows, NANT’s phone system was a basic Panasonic PBX with a limit of 30 internal extensions and 6 ISDN lines. “The system was limited and expensive, not to mention restrictive. Not only we could not have the 27 staff members at NANT and the staff at RAPIDTECH seamlessly connected to the phone system, but the company is in the process of moving to new premises, which means that we need to add at least 6 lines and 5 phones. This expansion would represent a high cost with the old system,” says David.

“I have made a rough estimate on some of the savings from using 3CX against the previous PBX”, added Buckley, “Hardware system: from £6,000 to £800; handsets: from £75 each to £45 each; and the BT bill down from £1,200 to £600. Also, 3CX has enabled us to reduce costs when it comes to having home-workers incorporated into the company’s phone system; this is a significant benefit.”

David found that installing and configuring 3CX IP PBX was a breeze. Its management and usage is also extremely easy, especially when compared to their previous PBX, “3CX is well laid out, with a good user interface and functionality, and it is far easier to manage and use than the system we had before, which requires a lengthy installation process and complicated instructions. Also, in a Windows-based environment as ours, we found that the fact that 3CX is also Windows-based is an advantage over an Asterisk®* alternative.”

Buckley has 3CX Phone System running on an HP Prolient Intel Xeon Duel Core server with one PSTN and four VoIP lines, and VoIPfone, Sipgate and PSTN Gateways. He is using fifteen hardware and fifteen soft phones, and when running tests he found that every phone that was tested with 3CX produced good quality results with minimal effort: X-Lite softphone, 3CX VoIP phone, SJ Labs, Axon, Linksys SPA 941 and Linksys SPA 3012.

During the deployment process Buckley used 3CX forums for support, something that he found really useful, “The 3CX forums are very helpful and have polite, friendly staff and community members.”

In 3CX, NANT and RAPIDTECH have found a phone system that delivers a full set of enterprise features that their old PBX could not offer without incurring a hefty investment. It has brought NANT Ltd.’s telephone infrastructure to the 21st Century.

Nick Galea, CEO at 3CX said, “Staff mobility, the elimination of phone tag and a reduction in administration and training time by IT staff are some of the main ChrisGreen1drivers in the migration to software-based PBX. We are delighted to see that an established UK business such as NANT is already enjoying these tangible business benefits from 3CX IP PBX.”

Chris Green, Managing Director at NANT Ltd. has only good things to say about 3CX Phone System for Windows, “It has significantly helped in achieving our business goals to expand with mobility.”

For David Buckley, it is all about being available to work remotely to provide off-site support to their sister company off hours and in emergencies, and also about offering his clients a telephone solution that helps businesses become more efficient and competitive. “3CX allowssmall and medium-sized businesses to work on a corporate scale. Fantastic!” Buckley concluded.
