Avaya phone system Chelsom


Chelsom is a third-generation family business designing, manufacturing and supplying lighting to the global hospitality and marine industries for over 70 years. With an award-winning reputation for inspirational product design, the business is committed to providing high quality and bespoke designs to hotels and cruise projects all over the world.

Project Overview

Chelsom had been running with an older Panasonic phone system which was coming towards end of life, running digital phones and ISDN30 phone lines. After reviewing their needs for the future, Chelsom decided it was time for an upgrade for the growing business.

Why Tech Advance?

After speaking with one of their suppliers, Tech Advance came recommended to the business as a trusted business communications provider and were invited to provide a proposal and recommendations for an upgraded new system.

The Solution

After looking at what would work best for the thriving business, Tech Advance recommended a state-of-the-art Avaya phone system using VoIP lines on site and VoIP/SIP lines for the external connectivity.

The system was upgraded at the end of 2019 and Chelsom are already seeing the benefits of such an advanced business Avaya phone system.

Benefits of the Avaya System

  • The ability to run phones and PC’s over a single network outlet and converged LAN architecture.
  • A new future proofed system that won’t be affected by BT’s planned ISDN switch off.
  • A new improved call reporting application and administration application.
  • Operating cost savings for the new VoIP system when compared with the older system being upgraded.


Comment from Zara Waters – Operations – “We were recommended to speak with Tech Advance from one of our other trusted suppliers for advice regarding our business telephone system as we were looking to update our office phone system. Following initial meetings, they were able to quickly understand our key drivers for the project and proposed a solution which delivered functional benefits to Chelsom whilst also reducing our operating costs.

Once we had chosen to proceed with the new system; we found the whole process of change to be well managed with Tech Advance providing the expertise we needed. They were very professional and took the lead on project management and handled any issues that came up, quickly and efficiently. We would have no hesitation in recommending Tech Advance to anyone looking for a good company to work with.”
