About us
Specialists in enterprise voice and collaboration
Our mission
Make every voice engineer platform-fluent
Enterprise voice has changed more in the last five years than in the twenty before. Calls now flow between CUCM clusters, Webex Calling, Microsoft Teams and SIP carriers, often all in the same organisation.
Most training still treats these as separate worlds. We don't. Our curriculum is built around the reality of hybrid enterprise voice: protocol fundamentals, deep platform skills on both Cisco and Microsoft, and the session border controllers that connect them.
What makes us different
- Cisco and Microsoft, together. One academy for CUCM, Webex Calling, Teams Phone and the interop between them.
- Transparent labs. We publish every lab topology and software version before you buy.
- Blueprint-mapped. Every course shows exactly which exam domains it covers.
- Built for working engineers. Short lessons, flexible labs and live sessions outside business hours.
Values
