IMS to the enterprise

摘要

Although most recent announcements about IP multimedia subsystem-enabled applications have centered on consumer voice services, network operators are indicating increased interest in IMS applications for enterprise customers. For example, BT recently announced the availability of its fusion fixed/mobile convergence service to enterprise markets. Last year, BellSouth and Cingular Wireless rolled out dual-mode Wi-Fi/GSM services in a trial deployment with Grey Advertising.
