摘要:
Systems and methods of establishing IP telephony sessions between enterprises are disclosed. A first enterprise requests an association with a second enterprise. Both enterprises and the second enterprise belong to the same federation. The association request is accepted, to establish an association between the first and second enterprises. In response to the acceptance, a direct routed path is established between the first enterprise and the second enterprise. One of the associated enterprises requests activation of an IP telephony service. If the request to activate references the association, an IP telephony session is established using the direct routed path.

A system for assisting in controlling real-time transport protocol flow through multiple networks is disclosed. The system utilizes at least a first computer and a second computer that is connected to the first computer, wherein the second computer comprises a second transceiver, a second memory having logic stored therein defining functions to be performed by the second computer, and a second processor. The second processor is configured by the second memory to perform the functions of: performing an inbound screen on route information received by the second computer, from the first computer, to determine if the received route information should be discarded; if the route information is not discarded, comparing the received and screened route information to a local policy defined with the second computer, and performing an outbound screen on the received and screened information prior to transmitting the received and screened information.

The present invention is an apparatus that receives various types of call record information when a called number is busy or does not answer, and converts the call record information into uniform format information suitable for recording messages on a message storage system. The system receives the different call forwarding information from different devices and translates and reformats that information into mailbox information suitable for controlling a message storage operation. The system includes one integration process for each type of switching device even when plural devices of a particular type are connected to the system. The integration processes provide a uniform packet routed to the message storage system. Packets arriving from the message storage system defined for a switching device are presented to the integration processes in a uniform format.

Methods and systems for routing call signaling messages are disclosed. One such method is performed in a session router. The method includes: maintaining a telephony route information base (TRIB) stored in the session router as a result of participation of the session router in telephony routing over internet protocol (TRIP). The TRIB allows multiple routes to the same destination. The method further comprises: using the TRIB to route the received call signaling messages to another session router. One such system includes memory and a processor. The processor is configured by instructions retrieved from the memory to: build and maintain, as a result of participation of the router in telephony routing over internet protocol (TRIP), a telephony route information base (TRIB) that allows multiple routes to the same destination; and use the TRIB to route a received call signaling message to another router.

Methods and computer-readable media are provided to select the optimal route for communicating a signaling message in a telecommunications networking environment. The method includes receiving a signaling message at a sending proxy that is responsible for sending the signaling message to its destination. To determine the best route, the sending proxy inspect its dynamic routing table to identify one or more potential routes that can be used to communicate the signaling message to its destination. The optimal route is determined by a numeric value, which may be based on one or more of a cost, the relationship between service providers, quality, or the like. Once the optimal route is determined, it is communicated from the sending proxy to the receiving proxy, often through one or more intermediary proxies.

A system and method for providing rapid rerouting of real-time transport protocol (RTP) multi-media flows is disclosed. Generally, a first endpoint is connected to a second endpoint, wherein the first endpoint comprises a transceiver, software stored within the first endpoint defining functions to be performed by the first endpoint, and a processor configured by the software. The processor is configured to perform the steps of, performing flow processing on a data packet received at a first endpoint, from a second endpoint, removing a multi-protocol label switching (MPLS) tag from the data packet, translating a source address and destination address of the data packet, and determining a forwarding destination if more than one destination address of the data packet is provided.

A system for assisting in controlling real-time transport protocol flow through multiple networks via use of a cluster of session routers is disclosed. The system utilizes a first computer and a cluster of computers, wherein the cluster of computers comprises at least two associated computers that are connected to the first computer. Each of the associated computers comprises a second transceiver, a second memory having logic stored therein defining functions to be performed by the associated computers, and a second processor. The second processor is configured by the second memory to perform the functions of: performing an inbound screen on route information received by an associated computer, from the first computer, to determine if the received route information should be discarded; if the route information is not discarded, comparing the received and screened route information to a local policy defined within the cluster of computers; and performing an outbound screen on the received and screened information prior to transmitting the received and screened information outside the cluster of computers.

A system and method provides a tandem switch and call control/management platform to establish a telephone connection (bridge) between two parties, the telephone connection being initiated by one of the parties. The tandem switch connects a telecommunications system (Centrex or PBX) with cellular or wireless telephones. If either party is disconnected from the tandem switch, the telephone connection between the tandem switch and the remaining party is maintained. The telephone connection is re-established by instructing the tandem switch to reconnect the disconnected party to the maintained party.
摘要:
A dynamic transaction network having multiple management stations, one or more terminals, and one or more databases is disclosed. The dynamic transaction network is capable of adding and removing network hosts (terminals, databases, and management stations) in real-time while continuing to service transaction requests. In addition, the dynamic transaction network is capable of transferring database fragments from a source database to a target database in real-time. In response to a transaction request from a caller, the terminal accesses information stored in a corresponding database via dynamic transportable logic. The dynamic transportable logic derives the location of relevant information in the database from input characteristic(s) of the transaction request. The transportable logic stored in the one or more terminals may be updated with transportable logic stored in the management station if a host determines that there is a difference between its transportable logic and the management station's transportable logic. A method for initializing a distributed, scalable, dynamic transaction network is disclosed as well. The method comprises: identifying each host; verifying each host has a current copy of the network configuration; updating the network configuration as required; and periodically repeating the process.
