摘要： A central directory system for a network of dial-up communication devices is described. In a preferred embodiment, the communication devices are videoconferencing devices. The system includes a directory management module coupled to the network and configured for importing and exporting directory information to and from a communication device. The directory information received by the management module can be grouped into address books by an access control module coupled to a database in which the address books can be stored. The access control module is further functional to manage access to the address books. Embodiments of the directory system provide systems and methods for providing intelligent dialing service to the dial-up communication device. A dialing algorithm determines a dialing sequence to connect communication devices through a network based on geographic dialing rules and information related to the requesting device.
