Abstract

A system and method for processing communication media in a regionally distributed communication platform that includes at a first platform region, establishing a communication session comprising establishing a media communication to at least one endpoint from the first region and establishing signaling communication to a second platform region; selecting a media resource in response to a change in media processing requirements of the communication session; when the selected media resource is outside the first region, routing media communication through a media resource outside of the first region; when the media resource is available in the first region, routing media communication through the media resource of the first region; and when the media resource is outside of the second region, storing the media communication in the first region at least temporarily and tunneling a branch of the media communication to a central media service in the second region.

Claims

1. A method for communicating in a distributed platform comprising:

providing a communication platform with resources in at least two regions, the resources including media resources and signaling resources;

initializing a communication session with connection to at least one endpoint, the communication session communicating media with the at least one endpoint, the media resources in the at least two regions including media services that process the media of the communication session, the media services including;

an active media service operating on the media of the communication session by altering or augmenting a state of the media of the communication session, and

a passive media service operating on the media of the communication session while maintaining a state of the media communication of the communication session;

associating the at least one endpoint with a first region;

determining a communication route topology according to media resource requirements of the communication session and availability of media resources in the regions; and

establishing the communication route topology of the communication session.

2. The method of claim 1, wherein determining a communication route topology further comprises determining a communication route topology according to communication quality.

3. The method of claim 2, wherein establishing the communication route topology of the communication session comprises in a first mode of a communication route topology, the communication route topology is maintained in a first region;

and in a second mode of a communication route topology, the communication route topology includes a segment between at least the first region and the second region.

4. The method of claim 3, wherein the communication session is initialized with a connection to at least a second endpoint;

further comprising associating the second endpoint with a second region, wherein determining a communication route topology comprises accounting for the regions of the first and second endpoint.

5. The method of claim 4, wherein the first region is distinct from the second region.

6. The method of claim 5, wherein the communication network topology includes a segment through a resource in a third region that is exclusive to the set of the first region, second region, and the third region.

7. The method of claim 1, wherein communication quality is based at least in part on media latency.

8. The method of claim 1, further comprising detecting a new service requirement in the communication session and updating the communication route topology.

9. The method of claim 8, wherein updating the communication route topology comprises transitioning a media communication route through a different sequence of resources in a set of regions distinct from the initial set of regions.

10. The method of claim 1, wherein determining a communication route topology comprises determining a media communication route topology based on media resources in the regions.

11. The method of claim 10,

wherein determining a communication route further comprises determining a signaling communication route topology based on signaling resources in the regions.

12. The method of claim 11, wherein the topology of the signaling communication route topology is independent of the topology of the media communication route topology.

13. The method of claim 1, wherein the communication session is initiated from a communication request.

14. The method of claim 13, wherein the communication request is transacted with a public switched telephone network (PSTN) provider.

15. The method of claim 14, wherein the communication request is transacted with a session initiation protocol (SIP) provider.

16. The method of claim 14, wherein the communication request is transacted with a internet protocol (IP) communication provider.

17. The method of claim 14, wherein the communication request is received in the form of an application programming interface (API) request.

20. The method of claim 1, wherein the media services include at least one of Dual-tone Multi-frequency (DTMF) detection, media recording, text-to-speech (TTS), speech recognition, transcoding, input detection, answering machine detection, conferencing and communication queuing.

18. A method for communicating in a distributed platform comprising:

providing a communication platform with media services in at least two regions;

initializing a communication session with connection to at least one endpoint, the communication session communicating media with the at least one endpoint, the media services including;

an active media service operating on the media of the communication session by altering or augmenting a state of the media of the communication session, and

a passive media service operating on the media of the communication session while maintaining a state of the media communication of the communication session;

associating the at least one endpoint with a first region;

determining a communication route topology according to media service requirements of the communication session and availability of media services in the regions; and

establishing the communication route topology of the communication session.

19. The method of claim 18, wherein the media services include at least one of Dual-tone Multi-frequency (DTMF) detection, media recording, text-to-speech (TTS), speech recognition, transcoding, input detection, answering machine detection, conferencing and communication queuing.
