Abstract

In one embodiment, the method of processing telephony sessions includes: communicating with an application server using an application layer protocol; processing telephony instructions with a call router; and creating call router resources accessible through a call router Application Programming Interface (API). In another embodiment, the system for processing telephony sessions includes: a call router, a URI for an application server, a telephony instruction executed by the call router, and a call router API resource.

Claims (42)

1. A non-transitory computer-readable medium comprising instructions that, in response to execution by a processing device, cause the processing device to perform operations comprising:

initializing, using an application programming interface (API) call to a call router, a telephony session between a first application associated with a first party and at least one second application associated with a second party;

receiving, from the call router, call state data of the telephony session;

in response to determining that the call state data indicates an in-progress state of the telephony session, performing at least one of: transmitting a first audio via the telephony session or receiving a second audio via the telephony session; and

in response to detecting a termination event associated with the telephony session, causing the call router to terminate the telephony session.

2. The non-transitory computer-readable medium of claim 1 , wherein:

the API call to the call router is via a uniform resource locator (URL).

3. The non-transitory computer-readable medium of claim 1 , wherein the call state data comprises a status indicator of a command.

4. The non-transitory computer-readable medium of claim 1 , wherein the call state data is received as parameters to a uniform resource locator (URL) provided by the first party.

5. The non-transitory computer-readable medium of claim 1 , wherein the operations further comprise:

providing, using a second API call to the call router, an instruction to collect dual tone multi frequency (DTMF) digits received in the telephony session.

6. The non-transitory computer-readable medium of claim 1 , wherein the API call comprises a unique identifier of the telephony session.

7. The non-transitory computer-readable medium of claim 1 , wherein the operations further comprise:

providing, using a second API call to the call router, an instruction to hold the telephony session.

8. A method comprising:

initializing, using an application programming interface (API) call to a call router, a telephony session between a first application associated with a first party and at least one second application associated with a second party;

receiving, from the call router, call state data of the telephony session;

in response to determining that the call state data indicates an in-progress state of the telephony session, performing at least one of: transmitting a first audio via the telephony session or receiving a second audio via the telephony session; and

in response to detecting a termination event associated with the telephony session, causing the call router to terminate the telephony session.

9. The method of claim 8 , wherein:

the API call to the call router is via a uniform resource locator (URL).

10. The method of claim 8 , wherein the call state data comprises a status indicator of a command.

11. The method of claim 8 , wherein the call state data is received as parameters to a uniform resource locator (URL) provided by the first party.

12. The method of claim 8 , further comprising:

providing, using a second API call to the call router, an instruction to collect dual tone multi frequency (DTMF) digits received in the telephony session.

13. The method of claim 8 , wherein the API call comprises a unique identifier of the telephony session.

14. The method of claim 8 , further comprising:

providing, using a second API call to the call router, an instruction to hold the telephony session.

15. A system comprising:

one or more processors; and

a memory that stores instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

initializing, using an application programming interface (API) call to a call router, a telephony session between a first application associated with a first party and at least one second application associated with a second party;

receiving, from the call router, call state data of the telephony session;

in response to determining that the call state data indicates an in-progress state of the telephony session, performing at least one of: transmitting a first audio via the telephony session or receiving a second audio via the telephony session; and

in response to detecting a termination event associated with the telephony session, causing the call router to terminate the telephony session.

16. The system of claim 15 , wherein:

the API call to the call router is via a uniform resource locator (URL).

17. The system of claim 15 , wherein the call state data comprises a status indicator of a command.

18. The system of claim 15 , wherein the call state data is received as parameters to a uniform resource locator (URL) provided by the first party.

19. The system of claim 15 , wherein the operations further comprise:

providing, using a second API call to the call router, an instruction to collect dual tone multi frequency (DTMF) digits received in the telephony session.

20. The system of claim 15 , wherein the API call comprises a unique identifier of the telephony session.
