Abstract

A system and method for facilitating signaling and media communication at a communication platform that includes receiving a communication request to a resource, wherein the communication request specifies a destination endpoint; establishing signaling and media communication in a session with the destination endpoint of the communication request; registering a callback resource to a signaling event of the session; monitoring signaling messages of the session; detecting the signaling event in the signaling messages of the session; and triggering the callback resource upon detecting the signaling event.

Claims

1. A method comprising:

receiving an incoming communication request of an originating endpoint;

establishing a media communication of a communication session according to the incoming communication request;

registering a callback resource to a signaling event message;

inspecting communication signaling messages of the communication session;

detecting the signaling event from communication signaling messages of the communication session;

triggering the callback resource upon detecting the signaling message type.

2. The method of claim 1, wherein triggering the callback resource comprises making an application layer communication to an external resource specified by the callback resource, wherein the application layer communication includes metadata of the session.

3. The method of claim 1, further comprising, during the session, receiving a signaling message that includes a parameter defining the callback resource;

authenticating tokens included in the signaling message and verifying an account; and

wherein registering a callback resource comprises registering the callback resource according to the parameter in the signaling message.

4. The method of claim 1, further comprising, receiving an application programming interface (API) communication that identifies the session and specifies the callback resource.

5. The method of claim 1, wherein the signaling message type signals that a connected endpoint is ending media communication.

6. The method of claim 5, wherein triggering the callback resource upon detecting the signaling message type comprises, enabling a second communication application mode.

7. The method of claim 6, further comprising accounting usage by an account in an original communication mode and accounting usage in the communication application mode, wherein usage in the original communication mode is distinct from usage in the communication application mode.

8. The method of claim 6, further comprising transitioning from the second communication application mode to a basic communication mode.

9. The method of claim 1, further comprising enabling media processing during the session, wherein media processing can selectively enable media recording during the session.

10. The method of claim 1, further comprising:

mapping a destination endpoint specified in the incoming communication signaling request to a primary account routing configuration;

if the primary account routing configuration specifies a signaling endpoint, establishing media communication of the communication session comprises routing an invitation signal to the signaling endpoint and establishing the media communication from an originating endpoint of the incoming communication request and the signaling endpoint;

if the primary account routing configuration specifies an application resource identifier, establishing media communication of the communication session comprises retrieving an application specified by the application resource identifier and processing the application in directing the media communication.

11. The method of claim 10, wherein the signaling endpoint includes metadata embedded in the endpoint;

and further comprising routing the incoming communication request to a signaling application module;
