Our IT Services team transitioned 160 users to a cloud-hosted Gamma Horizon Webex solution, ensuring staff had a reliable, modern system ahead of key events such as open days and new student registration.

Challenges

  • Minimising operational disruption - Migrating all users and numbering systems without impacting day-to-day school activity

  • Time-Critical deployment - Ensuring the new platform was fully operational ahead of major school events

  • Transition from legacy hardware - Managing the move from an ageing on-premises Mitel system to a modern cloud-based solution.

Solutions we delivered

  • Cloud-hosted Gamma Horizon Webex Platform - Deployment of a secure, public cloud communications solution

  • User & number migration - Seamless transition of 160 users from the legacy Mitel system, including numbering and call routing

  • Hardware-light setup - Simple on-site deployment requiring only handsets and analogue adapters.
