Why We’re a Recommended Telecoms Company

Company CEO

Following the pandemic we wanted to upgrade our telecommunication and internet system to allow us to work effectively from anywhere in the world. We went through an extensive tender process with three companies and chose Tetra Networks to manage our telecommunications and IT services. Since implementing the Telephony service with Tetra Networks across both our Bluebird Care and Care Homes we have had positive feedback from staff, customers, and healthcare professionals. Furthermore, both businesses have grown in turnover whilst allowing us to be more productive and effective in helping our customers and supporting staff.  I would highly recommend speaking to Tetra Networks to help you with your IT and Telecommunication systems. 

Managing Director

We have been a customer of Tetra Networks for a few years and would recommend their telecommunication services for your business.  Two years ago we upgraded to a cloud based solution, which allowed us more flexibility and control over our business and certainly came useful during the pandemic where staff were working from home. All staff were able to make and receive calls as if they were in the office, which was assuring to our customers, most of whom are vulnerable. Also worth mentioning is the after sales service, which has been great. The guys in technical support are efficient, professional and understand that business cannot afford any system downtime and are always on hand to get us up and running as quickly as possible. So good has the service been, we will not look elsewhere for our IT and telecom needs.
