Today, Microsoft begins life as a real competitor in the enterprise voice space. It has slain dragons (like enabling call access control and E911), faced mighty jousters (Miercom has called Lync a resilient, feature-rich, scalable UC system in their review), and emerged triumphant to compete for enterprise accounts looking for unified communications and collaboration (UC&C) solutions. Microsoft has amassed an impressive list of early adaptors — of both Office Communications Service Release 2 (OCS R2) and Lync — that includes large and small deployments with varied features/capabilities enabled.
Lync required Lighthouse accounts to use a wide array of services at significant scale, so I expect to see big accounts like Marquette University and the Dominican Republic Ministry of Education join current OCS enterprise voice users like Shell, Intel, AT Kearney, and Sprint on Microsoft’s “Customer Success Stories” page. In talking to many early adopters, I heard very few complaints about voice quality or reliability of the solutions, and:
Almost every firm using Lync is connecting employees together using Lync AND other Microsoft products.
Improved voice quality and reliability drives customer satisfaction and makes Microsoft’s story more credible in delivering UC&C solutions.
