Maintenance & Support

We pride ourselves on giving our clients a personal service and this extends to every element of our maintenance and support.

Telephone Systems

Buying a phone system will be one of the most significant purchases your organisation ever makes. We work with you to find and implement the most suitable solution.

Cheaper Line Rental

Would you bite our hand off if we told you we could potentially get you cheaper line rental and make more from the budget you’re spending on call charges? Thought so!

Call Management

Missed calls; they can be frustrating for the person making the call and mean lost organisation for the person unable to answer. Our call management can help improve your performance.

Specific Numbers

Want to let the people wanting to ring you know that you’re local? A geographical number could be ideal! National coverage? How about a 0800, 0844, 0845, 0870 or perhaps even an 03 number?

Unified Communications

Do you have multiple offices, teams, or systems? Our Unified Communication systems will allow you to share information faster and more efficiently throughout your organisation, helping you to perform smarter.

Call Centre Solutions

You want to give your customers a great experience. They don’t want to have to wait to speak with you and what is more, you don’t want them to have to wait; we facilitate that experience.

Audio Conferencing

The question for many organisations has long been how to get people that are in different geographical locations in the same place at the same time; we have the answer through our conferencing systems.


Do you have members of staff that often move around your office building, school or warehouse? Do you still need them to be contactable on the phone when on the move? Try our cordless DECT handsets.


We know the relationship you have with your stakeholders is at the heart of everything you do. Our Uninterruptible Power Supply (UPS) ensures that bond will never be broken.


In a world where providing a personal service to your stakeholders is vital, the ability to know exactly who is calling you before you even answer the phone is a valuable one. Welcome to Computer Telephone Integration (CTI).

Structured Cabling

Behind every telephone system there needs to be a robust infrastructure. We want your phone system to be with you for a long time; our cabling will make sure it does.

Our Experience

What our Clients Say

From the outset, Equations grasped what we wanted to achieve. We have wanted changes, often at short notice, and Equations has responded to meet our needs.- Happy Client
It was clear from the outset that very few products could meet even the majority of our requirements. Yet, Equations grasped what we wanted to achieve, and had a product in their portfolio (the Splicecom Maximiser) that could meet our needs both initially, and as we continue to grow. Since the initial installation we’ve added eight more users and have another thirteen scheduled. Equations have handled the additions and programming changes quickly and painlessly.- Happy Client
Equations are wonderful. I was given clear, simple-to-understand advice and a competitively-priced entry level system that has grown with my business.- Happy Client
