Best placed to support you
Telecoms companies are no longer the best placed to install configure and manage modern network based phone systems. Modern phone systems and their hardware are IT devices that connect to the same network and switches as your IT network. The PBX is now software driven. The connection to the rest of the telephone network is via your Internet connection, the same as your PCs. The best companies to manage these systems are IT companies.

Why use us for your telecoms?
Expertise
We have been using and installing Internet based phone systems at Tenacity for almost 20 years.
Cost
As we aren’t only a telecoms company, we can offer very attractive costs for customers who already have an IT support contract with Tenacity.
One point of contact
If there’s an issue, you won’t get any confusion over where the responsibility lies. If we support the phone system, you will only need to call us to get it resolved.
Meet PowerQ
We are excited to be able to offer our customers PowerQ, a Sheffield based start-up which gives the power to visualise call data. The software allows data to be pulled from your Asterisk or FreePBX system and then collates and displays the data into the metrics you need. From queue times, abandoned calls and call volumes, PowerQ gives you the overview of your phone system in order to make key decisions to maximise efficiency and capitalise on opportunity.
Simple Self-Managed System
Our system is so easy to manage, you can do it yourself - no need to wait on a support ticket for small changes. Add or remove users, update business hours, and configure call flows in just a few clicks.
Even better, use AI to generate announcements automatically: just type the text you’d like and let the system create a professional recording for your menus, queues, or out-of-hours messages.
