A data messaging system includes a first Internet Protocol (IP) switch that includes a processor. The data messaging system also includes a first gateserver coupled to the first IP switch and coupled to a second IP switch. The data messaging system includes a second gateserver that is coupled to the first IP switch and to the second IP switch. The data messaging system further includes a first gatekeeper coupled to the first IP switch. The first gatekeeper is adapted to detect a failure of the first gateserver and to route data to the second gateserver in response to detecting the failure.

Data and voice messaging system

In a particular embodiment, a system includes a messaging system configured to provide a messaging service. The messaging system includes a centralized Internet Protocol switching network, an Internet access subsystem, a voice access subsystem, a mail subsystem and a storage subsystem. One or more of the subsystems may be coupled to the centralized Internet Protocol switching network via one or more communication links integrated with and internal to the messaging system.

Provisioning unified messaging system services

A messaging system is disclosed that includes an Internet Protocol switching network, an Internet access subsystem coupled to the Internet Protocol switching network via a first communication link, a voice access subsystem coupled to the Internet Protocol switching network via a second communication link, a mail subsystem coupled to the Internet Protocol switching network via a third communication link, and a storage subsystem coupled to the Internet Protocol switching network. The first and second communication links transfer data according to different data protocol formats.

In a particular embodiment, a method includes providing a messaging service using a messaging system. The messaging system includes a centralized Internet Protocol switching network, an Internet access subsystem, a voice access subsystem, a mail subsystem and a storage subsystem. One or more of the subsystems may be coupled to the centralized Internet Protocol switching networks via a communication link integrated with and internal to the messaging system.

In a particular embodiment, a method of assigning identifications for unified messaging system subscribers is provided. The method includes assigning a unique temporary identity to a subscriber of a unified messaging service and upon the subscriber's first access to the unified messaging service, receiving a second identity selected by the subscriber.
