Case Study: MTU Aero Engines safeguards investments and modernizes communications with Unify's OpenScape Voice

MTU Aero Engines Gmbh Safeguarding Investments By Gradually Migrating Into The IP World With Openscape Voice.

MTU Aero Engines, Germany’s leading engine manufacturer with about 7,600 employees across multiple sites, needed a clear VoIP strategy to move into IP communications without abandoning its existing TDM investments. The company required a gentle, standards-based (SIP) migration with centralized administration and applications, easy extension to new locations, minimal disruption to operations, and compliance with its security policy.

Unify delivered a phased migration built on OpenScape Voice, HiPath 4000, OpenScape Xpressions and ComAssistant, using HiPath 4000 as media gateways to preserve legacy equipment while centralizing voicemail, user management and CTI. The result was protected investment, reduced operating and maintenance costs, centralized administration for multi-site control, simpler rollouts (e.g., a 400-port site in Poland) and a scalable, standards-based platform for future growth.
