We moved from BT to Zen Systems for our Telecoms and it's been fantastic. They helped us implement 3CX. The call quality is excellent and the system is incredibly user-friendly. Their customer support is always prompt and helpful, ensuring any issues are resolved quickly.
Highly recommend Zen Systems for any business looking for a reliable telecom solution!

We have trusted Zen with our IT support for the last 8 years and have always found the team to be very willing and able to support on all our IT and telecom needs. We have had a number of office moves, system upgrades and rather challenging internal database integration issues, all worked through by the Zen team.
Particular thanks to Dean, always happy to help and calm in a crisis. A superstar!

As a 3CX customer with a different service provider we were previously encountering very slow response times to issues raised, and an inability to correctly handle them when there were finally responded to.
This experience prompted me to switch to Zen Systems who demonstrated very clearly their expertise with 3CX. James Howard-Dobson and his team were extremely helpful in migrating us from our previous provider, responding with grace to challenges encountered along the way. I'm pleased to report that our service is now running very smoothly.
