RZDstroy is a transport infrastructure construction company whose 3,000 employees implement projects and manufacture products for the Russian Railways network. With 18 construction subsidiaries spread across Russia, timely communication is a key element for finishing projects on time and on budget. RZDstroy had deployed both a traditional private-branch exchange (PBX) telephony solution from Ericsson and a voice over IP (VoIP) solution to help employees communicate. RZDstroy wanted to find an enterprise-wide unified communications solution that would help its employees be more efficient and productive. To help decide on a solution, RZDstroy contacted CROC, a Microsoft Gold Certified Partner that provides system integration solutions and services some of the largest companies across Russia. CROC offered a unified communications solution based on Microsoft technologies, including Microsoft Exchange Server 2007, Microsoft Office Communications Server 2007 R2. In October of 2009, with the help of CROC engineers, RZDstroy began the full migration of Office Communications Server to its computers at its Moscow headquarters. At its main data center, it deployed two mediation servers and two AudioCodes Mediant 1000 media gateways to integrate Office Communications Server with its existing PBX telephony system. By December 2009, it had deployed the full solution to 2,000 of its employees.
