Abstract

A system and method for regional routing of internet protocol based real-time communication that includes registering a set of client application endpoint routes, comprising registering at least a first client gateway route of a first endpoint in a first region; receiving a communication invitation of the first endpoint; processing a set of communication instructions associated with the communication invitation and identifying a set of communication resources and at least a second endpoint; querying the client application endpoint routes and identifying a client gateway route of the second endpoint; and dynamically directing signaling path and media path of the communication according to the regional availability of the communication resources, the client gateway route of the first endpoint, and client gateway instance route of the second endpoint.

the communication processing server negotiating a first peer-to-peer media path between the second client device and the first client device via the first client gateway device and the third client gateway device, the first client gateway device providing media communication of the first peer-to-peer media path to the third client gateway device, and the third client gateway device providing media communication of the first peer-to-peer media path to the first client gateway device, and

responsive to selection of the second client gateway device;

the communication processing server negotiating a second peer-to-peer media path between the second client device and the first client device via the second client gateway device and the third client gateway device, the second client gateway device providing media communication of the second peer-to-peer media path to the third client gateway device, and the third client gateway device providing media communication of the first peer-to-peer media path to the second client gateway device,

wherein the second client gateway device is a real-time communication gateway device, and

wherein the third client gateway device is a real-time communication gateway device, and

wherein the first geographic region is different from the second geographic region.

2. The method of claim 1, wherein the first client device is constructed to communicate with the first client gateway device and the second client gateway device by using application based communication.

3. The method of claim 2, wherein the second client device is constructed to communicate with the third client gateway device by using application based communication.

4. The method of claim 1, wherein the second client device and the first client device are external to the hardware system.

5. The method of claim 1, wherein the communication processing server identifies the first client gateway device and the second client gateway device registered for the first communication endpoint.

6. The method of claim 1, wherein the communication processing server processes a set of communication instructions associated with the first communication invitation, and identifies a set of communication resources of the hardware system and at least the first communication endpoint.

7. The method of claim 6, wherein the communication processing server dynamically directs a signaling path and a media path of a communication of the first communication invitation according to regional availability of the communication resources, the first client gateway device, the second client gateway device, and the third client gateway device.

8. The method of claim 1, wherein the communication processing server selects one of the first client gateway device and the second client gateway device according to geographic location, and the communication processing server selects the first client gateway device having the same geographic region as a third client gateway device registered for the second communication endpoint, wherein the third client gateway device is a gateway device of the first geographic region.

9. The method of claim 1, wherein the communication processing server dynamically updates selection of the client gateway device of the first communication endpoint according to a change in at least one of user preference, location, usage history and presence information, and responsive to the change of selection, the communication processing server negotiates a third peer-to-peer media path between the second client device and the first client device via the third client gateway device and one of the first client gateway device and the second client gateway device based on the updated selection.

10. The method of claim 9,

wherein the first client gateway device, the second client gateway device and the third client gateway device are constructed to provide real-time media communication over an internet protocol, and

wherein the media communication includes one of audio media stream communication and video media stream communication.

11. The method of claim 10, wherein the communication processing server selects one of the first client gateway device and the second client gateway device according geographic location of the first client gateway device and geographic location of the second client gateway device.

12. The method of claim 1,

wherein the first client gateway device is a real-time audio communication gateway device that is constructed to provide real-time audio communication between at least the first client device and the second client device via a public network,

wherein the second client gateway device is a real-time audio communication gateway device that is constructed to provide real-time audio communication between at least the first client device and the second client device via a public network, and

wherein the third client gateway device is a real-time audio communication gateway device that is constructed to provide real-time audio communication between at least the first client device and the second client device via a public network.

13. The method of claim 1,

wherein the first client gateway device is a real-time video communication gateway device that is constructed to provide real-time video communication between at least the first client device and the second client device via a public network,

wherein the second client gateway device is a real-time video communication gateway device that is constructed to provide real-time video communication between at least the first client device and the second client device via a public network, and
