On-Premises Systems

We take pride in offering a wide range of on-premises solutions for all types of businesses. We supply top-end systems for enterprise users, call-centres, and SME’s. Our ethos is unwavering; we will always  recommend the ideal system for any given environment or business.

The hardware needed to run an on-premises phone system is housed in a safe place in your business, such as a rack. The system is then operated and maintained exclusively on-site.

The component parts of an on-premises phone system are as follows. The lines, which are broadband based. The controller which is known as the ‘brains’ of the system, and handles all the functionality, and the third component which are the handsets.

An on-premises phone system is a telephone system that is physically located on the premises of the business or organisation that uses it. The term “on-premises” refers to the fact that the phone system is not hosted by a third-party service provider. Instead, the phone system controller is housed within your own business location. 

You may quickly expand or shrink your capabilities with an on-premises phone system. This can be accomplished by adding or removing lines, extensions, and features. Systems also come with a variety of functions and capabilities such as intelligent call routing, conferencing, voicemail, and call recording and monitoring which can be customised to meet the specific needs of the business. 


On-premises phone systems are ideal for businesses that require a higher level of security and control over their telecom infrastructure or have specific communication requirements. As the system is stored on-site at your business location you can ensure that your data and calls are secure and protected.

What Clients Say About Us

Joanne Bloomfield, CEO JDE Marketing

"My telecom system was a daily pain! It never worked the way I needed it to, and cost more than I was comfortable with. Then I was introduced to Sloane Curtis Solutions. Fantastic service, the right tech for my company and a much better price than I was paying. I’m now a happy camper. Highly recommend.”

Craig Rosenthal, CEO Medical Equipment Supplier

“We needed to plan for the end of ISDN services, but we didn’t know where to start. The Sloane team not only helped us develop a roadmap to phase out our old system, but they also helped with creating for the future, identifying the right kit and training our whole team so the switch over was seamless.”

Janet Simmons, MD Mobility Solutions

“When we returned to being fully office based after lockdown, a large percentage of our team wanted to continue working from home. Sloane Curtis Solutions leaned into the task of finding the right solution for our new normal of working both at home and in the office. Superb service at every stage – highly recommend.”

Robert Yelland, IT Director PPE Provider

“When it came time to upgrade our system Gary and his team helped us figure out what we needed. We had always had an office-based telephony system, but it was clear that moving to a hosted solution was the way forward for us. HUGE saving and no hassle to switch over.”

Jean Hartzel, MD Utilities Management

“We had four different numbers in play for our UK offices and it was causing confusion with both our customers and within our internal operations. Sloane reviewed our set-up, built out a plan to unify our calls with a non-geographic number and create a more professional front of office via the use of an App for our remote workers and sales team. Great company to work with.”
