Abstract

A method and system for operating a multitenancy telephony system including a call queue that stores call requests received from a plurality of users; an expandable and contractible telephony resource cluster that establishes call sessions for call requests; a analysis system that calculates capacity requirements of the system; a resource allocator that manages the scaling and operation of the telephony resource cluster; and a plurality of telephony network channels that are used as telephony communication channels for call sessions.

Claims

1. A method comprising:

receiving, from an external server system, an outbound communication request;

in response to receiving the outbound communication request, establishing a communication session to a communication endpoint;

generating a communication resource for the communication session, the communication resource storing a state of the communication session; and

receiving, from the external server system, a request including an identifier of the communication resource; and

in response to receiving the request;

gathering the state of the communication session from the communication resource, and

providing the state of the communication session to the external server system.

2. The method of claim 1, wherein the outbound communication request is to initiate a call with the communication endpoint.

3. The method of claim 1, wherein the outbound communication request is to transmit a message with the communication endpoint.

4. The method of claim 1, wherein the request including the identifier is an Application Programming Interface (API) request.

5. The method of claim 1, wherein the communication session is established using a public switched telephony network (PSTN) channel.

6. The method of claim 1, wherein the identifier of the communication resource is a Uniform Resource Identifier (URI).

7. The method of claim 1, wherein the state of the communication session is provided to the external server system using an HyperText Transfer Protocol (HTTP) message.

8. A system comprising:

one or more computer processors; and

one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the system to perform operations comprising;

receiving, from an external server system, an outbound communication request;

in response to receiving the outbound communication request, establishing a communication session to a communication endpoint;

generating a communication resource for the communication session, the communication resource storing a state of the communication session; and

receiving, from the external server system, a request including an identifier of the communication resource; and

in response to receiving the request;

gathering the state of the communication session from the communication resource, and providing the state of the communication session to the external server system.

9. The system of claim 8, wherein the outbound communication request is to initiate a call with the communication endpoint.

10. The system of claim 8, wherein the outbound communication request is to transmit a message with the communication endpoint.

11. The system of claim 8, wherein the request including the identifier is an Application Programming Interface (API) request.

12. The system of claim 8, wherein the communication session is established using a public switched telephony network (PSTN) channel.

13. The system of claim 8, wherein the identifier of the communication resource is a Uniform Resource Identifier (URI).

14. The system of claim 8, wherein the state of the communication session is provided to the external server system using an HyperText Transfer Protocol (HTTP) message.

15. A non-transitory computer-readable medium storing instructions that, when executed by one or more computer processors of one or more computing devices, cause the one or more computing devices to perform operations comprising:

receiving, from an external server system, an outbound communication request;

in response to receiving the outbound communication request, establishing a communication session to a communication endpoint;

generating a communication resource for the communication session, the communication resource storing a state of the communication session; and

receiving, from the external server system, a request including an identifier of the communication resource; and

in response to receiving the request;

gathering the state of the communication session from the communication resource, and providing the state of the communication session to the external server system.

16. The non-transitory computer-readable medium of claim 15, wherein the outbound communication request is to initiate a call with the communication endpoint.

17. The non-transitory computer-readable medium of claim 15, wherein the outbound communication request is to transmit a message with the communication endpoint.

18. The non-transitory computer-readable medium of claim 15, wherein the request including the identifier is an Application Programming Interface (API) request.

19. The non-transitory computer-readable medium of claim 15, wherein the communication session is established using a public switched telephony network (PSTN) channel.

20. The non-transitory computer-readable medium of claim 15, wherein the identifier of the communication resource is a Uniform Resource Identifier (URI).
