The document presents a total cost of ownership (TCO) benchmarking study conducted by Aberdeen Group on various unified communications (UC) solutions across 236 corporate environments. It emphasizes the growing importance of evaluating both capital and operational costs over the expected lifespan of UC systems, highlighting implementation, training, and ongoing support expenses that often exceed initial costs. The findings suggest a significant variation in TCO across different UC platforms, detailing specific cost components and the need for companies to take a holistic approach to assess their communications investments.
