Convergence is the ability to combine voice, data and video over a single network infrastructure and single platforms. IT encompasses the coming together of voice and data applications in a common networked environment. Its significance is the integration of communications applications with key business applications. The business applications are usually tied to business processes, which are central to an organization's operations. Converged communications help organizations to unlock network value by realising the benefits of tying together applications that until now have been completely separate.
IP is becoming the de-facto communication standard that will glue the multitude of business applications available, into a cohesive infrastructure to support your business.
