Gateway devices and Call Managers are not limited to geographical boundaries. A properly designed system would easily provide the scalability, redundancy and fault tolerance that highly available networks require. The unified communications approach relates very closely to the Internet model that the Department of Defense designed. The Cisco Call Manager server clustering approach represents a highly available network model that can meet disaster recovery requirements when aligned with the proper underlying quality of service (QoS)- enabled infrastructure. QoS is the glue of the network that guarantees the quality level necessary for real-time communications, such as voice and video | Global Knowledge Expert Reference Series ofWhite Papers Cisco Unified Communications Unifying Communications Infrastructure 1-800-COURSES Cisco Unified Communications Unifying Communications Infrastructure Dennis J. Hartmann Global Knowledge Instructor CCIE CCVP. CCSI Introduction The communications devices of today are physically disparate systems with many technical intricacies. There are great advantages to using these devices yet they do not represent a cohesive collaboration system that has the intelligence or power to meet the challenge for business to deliver higher-quality products with a lower time to market at competitive costs. As product life cycles become shorter and shorter business is forced to transform itself on a dime. The communications devices of today can become down right frustrating to use at times. Technology should solve a problem or provide an avenue that will lead to productivity gains and innovation. When technology is purchased for the sake of having the latest technology the business suffers. The systems of today must be joined cohesively to ease the proliferation of new empowering technology. Management can easily align this one unified system to the business core values while delivering on the commitment to provide one system that meets all of the company s communications needs. Cisco s unified communications vision combines individual systems with different communications capabilities into a cohesive powerful communications ecosystem. The ecosystem is the enabling factor in allowing a business to revolutionize itself overnight. The power of the system is not the system itself but the human capabilities that are enabled from the utilization of the system. Human collaboration has the power to transform unified communications is the enabler. Unified Communications Systems Powerful business leaders are continuously faced with a similar challenge How do I reinvent the corporate culture and business processes of .
