Business communications standardization in ETSI

Enterprise networks are in the process of a major and rapid evolution toward IP. At the same time, the 3GPP IP multimedia subsystem is gaining momentum in the telecom industry as the target architecture for delivering and controlling multimedia services in carrier-grade IPbased networks. As a logical consequence, standards are emerging that enable the support of business trunking and hosted enterprise services using the IMS. This article provides insight into the benefits of this approach and takes an in-depth look at related ETSI standards.
