Abstract: A Media Gateway proxy receives a message and parses the message. The message contains an attribute, sub-command, and a destination address. The proxy stores the message and the attributes. Each of the attributes corresponds to a selected one of a plurality of Media Gateways. Each of the gateways has an address. The proxy finds in the memory the address of the selected Media Gateway using the destination address and the attribute. The proxy then forms a message using said sub-command, said address, and said attribute and transmits the message to the destination Media Gateway.

Abstract: A method and system for providing directory based services is provided. The directory service may process an ambiguous destination identifier from a call-session request to multiple database entries in a directory server, and return an appropriately constructed response that can be interpreted by a user as a prompt for additional input to refine the destination identifier. The possible matches could be sent as a list of possible choices. The user can then select the desired match from the list and send a follow-on request including the selection to the directory server. Based on the selection, the directory server will then either send additional possible matches to the user or obtain a contact address corresponding to the selection. After resolving the ambiguous match to a unique destination identifier, a call can then be established.

Abstract: A system and method for providing user mobility handling in a network telephony system is provided. In one embodiment, the method includes receiving a register request from a network entity on a first domain and modifying a user identifier in the register request. A registration database is preferably updated with the modified user identifier. The modified register request is transmitted via a network to a network entity on a second domain. An authentication process preferably takes place between the network entity on the first domain and the network entity on the second domain. If successful, a confirmation is received via the network from the network entity on the second domain. Various embodiments of the invention may, for example, allow a user typically located in a home domain to temporarily move to a visiting domain, while maintaining the user's home domain user identifier. Preferred embodiments utilize the Session Initiation Protocol.

Abstract: A system and method for routing information includes a resource manager. The resource manager includes a configuration table. The configuration table includes at least one group of physical gateway addresses, each of the at least one group of physical gateway addresses has a single and unique logical identifier. The resource manager is coupled to a plurality of gateways. A proxy coupled to the resource manager. The resource manager receives a register request message from a selected one of the plurality of gateways.

Abstract: A provisioning server (11) having various operating modes serves to provide a unified logical view of a soft switch (10) to a user via a display (14) and in response to receiving new service information from the user, provisioning corresponding configuration parameters to various of the logical communications support platforms (10A-F) that comprise the soft switch. Depending upon the mode of operation, the provisioning server can also receive current configuration parameter information from the logical platforms.

Abstract: A telephony system and method having a switch for analog voice and data signals that is connected to a first network, and a router for routing Internet Protocol packets that is connected to a second network using Internet Protocol addressing. The telephony system and method also includes a telephony gateway that is connected to both the switch and the router for converting analog voice signals into Internet Protocol packets and for converting Internet Protocol packets into analog voice signals, the telephony gateway being connected, and a remote access server that is connected to both the switch and the router for converting analog data signals into Internet Protocol packets and for converting Internet Protocol packets into analog data signals. The switch may have a switch matrix capable of being connected to the Public Switched Telephone Network, a line rack with a plurality of line cards connected to the switch matrix, and a trunk rack with a plurality of trunk cards connected to the switch matrix.
