Transitioning Aerospace Communications

Situation

A global aerospace organization with tensof thousands of employees across Canada and Europe, had undergone multiplel arge-scale organizational changes, including cloud migrations, business mergers, and later separations. Their communications environment relied heavily on Cisco-based telephony, which introduced significant cost,operational complexity, and management overhead. With Microsoft 365 alreadyin place, the client saw an opportunity to simplify and modernize theircommunications stack.

Task

Red X Carbon was engaged to design andexecute the transition from Cisco telephony to Microsoft Teams Telephonyfor a large, regulated aerospace environment. The objective was to reducecomplexity and cost, maintain business continuity, and support a wide range ofmission-critical devices—including shop-floor phones, security turnstiles, andemergency systems—without compromising safety or compliance.

Action

Red X Carbon acted as a core architecture and program leadership partner, designing the telephony migration while Cisco systems were gradually decommissioned. The team addressed complex requirements such as:

• Supporting thousands of heterogeneous devices beyond standard user endpoints
• Ensuring emergency and security call handling in regulated environments
• Integrating third-party solutions for call recording and  attendant consoles where Microsoft Teams capabilities were insufficient at the time
• Stepping in mid-project to course-correct deployment   challenges, extend timelines responsibly, and stabilize delivery

Red X Carbon leveraged a flexible benchof subject-matter experts across cloud architecture, security, identity,and device management, enabling rapid problem resolution across interconnected systems.

Result

The client successfully transitioned alarge portion of its workforce from Cisco to Microsoft Teams Telephony,consolidating communications into a single, familiar platform. The solutionreduced technology duplication, improved user experience, and positioned the environment for long-term manageability by incumbent services teams. The client remained highly satisfied and continues to engage Red X Carbon for ongoing and future initiatives.
