Unified Communications Solutions (UCS) are an orchestrated communication and collaboration across locations, time and medium to accelerate business results. It is achieved through the convergence of real-time, near-real time and non real time business communication applications including calling, 
conferencing, messaging, contact books, calendaring, collaboration and rich presence with voice, video, text and visual elements. UCS can improve customer service by simplifying interaction between customers and the enterprise, and by making workers more available and 
responsive. It also reduces costs by lowering corporate communication and mobile phone expenses, by reducing meeting and travel expenses and cutting real estate costs.
