Abstract

A request to establish a communication session is received at a cloud communication application. The request is from a first enterprise communication device to establish a communication session with a second communication device that is typically also within the enterprise. In response to receiving the request to initiate the communication session, the cloud communication application directs the first enterprise communication device to use an enterprise media server for sending a media stream of the first communication session. This allows the cloud communication application to provide one or more cloud services for the media stream via a communication channel that has been previously established between the cloud communication application and the enterprise media server. This results in the media stream being sent within the enterprise, thus, providing enhanced security. In addition, less bandwidth is required because the media streams do not have to be sent to and from the cloud.

Claims

1. A method for managing communication sessions comprising:

receiving a request to establish a communication session at a cloud communication application, wherein the request is from a first enterprise communication device to establish a communication session with a second communication device;

in response to receiving the request to initiate the communication session, directing the first enterprise communication device to use an enterprise media server for sending a media stream in the first communication session; and

providing one or more cloud services for the media stream via a communication channel between the cloud communication application and the enterprise media server.

2. The method of claim 1, wherein the communication channel is established by the enterprise media server contacting a cloud media server Session Initiation Protocol (SIP) User Agent (UA).

3. The method of claim 1, wherein the second communication device is an enterprise communication device, wherein the enterprise media server comprises a plurality of enterprise media servers, and further comprising:

determining locations of the first and second enterprise communication devices within the enterprise; and

in response to determining the locations of the first and second enterprise communication devices within the enterprise, selecting one or more of the plurality of enterprise media servers as the enterprise media server for use by the first enterprise communication device based on the locations of the first and second enterprise communication devices within the enterprise.

4. The method of claim 1, wherein the request is a Session Initiation Protocol (SIP) INVITE, wherein the SIP INVITE is sent directly to the cloud communication application.

5. The method of claim 1, wherein the request is a first Session Initiation Protocol (SIP) INVITE, wherein a second SIP INVITE is initially sent to the enterprise media server and then redirected by the enterprise media server to the cloud communication application via the communication channel.

6. The method of claim 5, where the redirecting step comprises:

in response to receiving the second SIP INVITE, sending an Session Description Protocol offer to a cloud media server SIP User Agent (UA); and

sending the first SIP INVITE from the could media server UA to the cloud communication application.

7. The method of claim 6, wherein a first Session Initiation Protocol (SIP) dialog between the cloud communication application and the SIP cloud media server UA is established via the communication channel and wherein a second SIP dialog between the media server and the first enterprise communication device is established.

8. The method of claim 1, wherein the one or more cloud services are one or more Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) and further comprising:

creating a SIP dialog between the enterprise media server and the first enterprise communication device via the cloud communication application and the one or more B2BUAs.

9. The method of claim 1, wherein the request is a Web Real Time Communication (WebRTC) request.

10. The method of claim 9, further comprising:

in response to receiving the WebRTC request, sending a Session Initiation Protocol (SIP) INVITE to a cloud media server User Agent (UA).

11. A system for managing communication sessions comprising:

a cloud communication application configured that receives a request to establish a communication session, wherein the request is from a first enterprise communication device to establish a communication session with a second communication device, directs the first enterprise communication device to use an enterprise media server for sending a media stream in the first communication session in response to receiving the request to initiate the communication session, and provides one or more cloud services for the media stream via a communication channel between the cloud communication application and the enterprise media server.

12. The system of claim 11, wherein the second communication device is an enterprise communication device, wherein the enterprise media server comprises a plurality of enterprise media servers, and wherein the cloud communication application determines locations of the first and second enterprise communication devices within the enterprise and selects one or more of the plurality of enterprise media servers as the enterprise media server for use by the first enterprise communication device based on the locations of the first and second enterprise communication devices within the enterprise.

13. The system of claim 11, wherein the request is a Session Initiation Protocol (SIP) INVITE, wherein the SIP INVITE is sent directly to the cloud communication application.

14. The system of claim 11, wherein the request is a first Session Initiation Protocol (SIP) INVITE, wherein a second SIP INVITE is initially sent to the enterprise media server and then redirected by the enterprise media server to the cloud communication application via the communication channel.

15. The system of claim 14, where the media server sends an Session Description Protocol offer to a cloud media server User Agent (UA) in response to receiving the second SIP INVITE and the cloud media server UA sends the first SIP INVITE to the cloud communication application.

16. The system of claim 15, wherein a first Session Initiation Protocol (SIP) dialog between the cloud communication application and the SIP cloud media server UA is established via the communication channel and wherein a second SIP dialog between the media server and the first enterprise communication device is established.

17. The system of claim 11, wherein the one or more cloud services are one or more Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs), wherein the cloud communication application creates a SIP dialog between the enterprise media server and the first enterprise communication device via the cloud communication application and the one or more B2BUAs.

18. The method of claim 11, wherein the request is a Web Real Time Communication (WebRTC) request.

19. The system of claim 18, wherein the cloud communication application sends a Session Initiation Protocol (SIP) INVITE to a cloud media server User Agent (UA) response to receiving the WebRTC request.

20. A non-transient computer readable medium having stored thereon instructions that cause a processor to execute a method, the method comprising:

instructions to receive a request to establish a communication session at a cloud communication application, wherein the request is from a first enterprise communication device to establish a communication session with a second communication device;

in response to receiving the request to initiate the communication session, instructions to direct the first enterprise communication device to use an enterprise media server for sending a media stream in the first communication session; and

instructions to provide one or more cloud services for the media stream via a communication channel between the cloud communication application and the enterprise media server.
