Abstract

A method, system, and computer program product for routing network traffic (calls in a Voice over Internet Protocol (VoIP)), which expands the capabilities of existing systems by providing faster and more efficient direction of network traffic, is disclosed. A routing management system includes a routing manager which maintains a list of local routes, establishes and manages connections to the routing server(s), exports routes to the routing server(s), imports disseminated routes from the routing server(s), obtains static global and dynamic routes from the routing server(s), caches those routes for future use, finds all matching routes for a particular number dialed by the user, and prioritizing those routes based on timing, access and ordering information. An additional embodiment contains at least one routing server which provides look-up services for gateway server(s), allows export of local routes from gateway server(s), and distributes translation data; and at least one gateway server which handles calls received on either the Internet protocol (IP) or traditional telephony networks. The gateway server bridges calls between the different kinds of networks, interacts with users, interfaces with the routing system.

Claims

1. A system, comprising:

a gateway server configured to communicate with a routing server and database server, receive one or more calls from a public switched telephone network, and route the one or more calls over a packet switched network, wherein the gateway server comprises a routing manager, and wherein the routing manager is implemented on one or more processors coupled to a memory having instructions stored thereon that, if executed by the one or more processors, cause the one or more processors to;

import routes from the routing server and export routes to the routing server;

maintain a list of the imported and exported routes;

receive a request for a route from the gateway server;

find one or more matching routes for a specific telephone number from the list of imported and exported routes based on the received request from the gateway server;

prioritize the one or more matching routes based on one or more parameters and including determining an order in which the gateway server will attempt to route a call received by the gateway server; and

provide the one or more matching routes to the gateway server in order to route the call received by the gateway server;

wherein the gateway server, the routing server, and the database server are communicatively coupled to;

a management system implemented on one or more processors coupled to a memory having instructions stored thereon that, if executed by the one or more processors, cause the one or more processors to send messages over the packet switched network; and

a network manager system implemented on one or more processors coupled to a memory having instructions stored thereon that, if executed by the one or more processors, cause the one or more processors to query a client database to determine an update and further configured to send a message representative of the update to at least one of the gateway server, routing server, or database server over the packet-switched network.

2. The system of claim 1, wherein:

the database server is coupled to a provisioning system.

3. The system of claim 1, wherein the exported local routes are stored as dynamic routes.

4. The system of claim 1, wherein the one or more processors of the routing manager further utilize the instructions to register system components.

5. A method, comprising:

receiving one or more calls from a public switched telephone network and routing the one or more calls over a packet switched network via a gateway server;

managing route usage on the gateway server, wherein managing route usage includes;

importing routes from a routing server and exporting routes to the routing server;

maintaining a list of the imported and exported routes;

receiving a request for a route from the gateway server;

finding one or more matching routes for a specific telephone number from the list of imported and exported routes based on the received request from the gateway server;

prioritizing the one or more matching routes based on one or more parameters, wherein the prioritizing includes determining an order in which the gateway server will attempt to route a call received by the gateway server using the one or more matching routes;

providing the one or more matching routes to the gateway server in order to route the call received by the gateway server;

configuring system properties with a management system, wherein messages are sent between the gateway server and the management system over the packet switched network; and

updating system components based, at least in part, on a message representative of an update detected in a client database.

6. The method of claim 5, further comprising:

accessing database records with a provisioning system.

7. The method of claim 5, further comprising:

registering system components.

8. The method of claim 5, further comprising transforming the exported local routes into dynamic routes.

9. A computer-readable device having stored thereon executable program instructions, execution of which by a computing device causes the computing device to perform operations comprising:

receiving one or more calls from a public switched telephone network and route the one or more calls over a packet switched network using a gateway server;

managing route usage on the gateway server, wherein managing route usage includes;

importing routes from a routing server and exporting routes to the routing server;

maintaining a list of the imported and exported routes;

receiving a request for a route from the gateway server;

finding one or more matching routes for a specific telephone number from the list of imported and exported routes based on the received request from the gateway server;

prioritizing the one or more matching routes, wherein the prioritizing includes determining an order in which the gateway server will attempt to route a call received by the gateway server using the one or more matching routes;

providing the one or more matching routes to the gateway server in order to route the call received by the gateway server;

configuring system properties with a management system, wherein messages are sent between the gateway server and the management system over the packet switched network; and

updating system components based, at least in part, on a message representative of an update detected in a client database.

10. The non-transitory computer-readable medium of claim 9, wherein the instructions further cause the computing device to access database records with a provisioning system.

11. The non-transitory computer-readable medium of claim 9, wherein the instructions further cause the computing device to register system components.

12. The non-transitory computer-readable medium of claim 9, wherein the instructions further cause the computing device to transform the exported local routes into dynamic routes.
