Why Train Collab Academy

Built by engineers who run enterprise voice for a living

We're not a content library. Every course is designed around what it takes to deploy, operate and fix Cisco and Microsoft collaboration in production.

  • CCIE-level expertise

    Courses are designed and taught by CCIE Collaboration engineers and senior Teams voice specialists.

  • Enterprise deployment experience

    Every lesson draws on real deployments, from 500-seat sites to global multi-cluster estates.

  • Real troubleshooting scenarios

    Broken-call labs built from the incidents engineers actually face: traces, debugs and captures.

  • Hands-on labs

    Browser-based pods running real CUCM, CUBE, Expressway, Webex and Microsoft 365. No simulations.

  • Migration expertise

    Proven patterns for moving from CUCM to Webex Calling or Teams Phone without disrupting the business.

  • Cisco + Microsoft hybrid

    One academy for both platforms and the CUBE layer that connects them, as most enterprises run them.

Academies

Three specialist academies. One connected skill set.

Each academy is a complete learning path with labs, certification mapping and a clear sequence, and they're designed to work together.
