Abstract

Providing a proxy server feature includes initiating the proxy server feature at an endpoint of a number of endpoints. Registration information comprising addresses for the endpoints is received and then stored in a routing table at the endpoint. The endpoint locates a callee endpoint using the routing table in order to establish a session with the callee endpoint.

First claim

What is claimed is:

1. A method for providing a proxy server feature, comprising:
initiating a proxy server feature at a first endpoint of a plurality of endpoints, wherein each endpoint of the plurality of endpoints is operable to provide the proxy server feature, and wherein initiating the proxy server feature at the first endpoint of the plurality of endpoints further comprises:
accessing feature logic using a service framework at the first endpoint, the feature logic stored on the first endpoint operating as the proxy server, the feature logic defining the proxy server feature and an event handler that indicates a response to an event; and
initiating the proxy server feature by executing the feature logic stored on the first endpoint;

receiving registration information corresponding to the plurality of endpoints, the registration information corresponding to an endpoint comprising an address for the endpoint, and wherein receiving registration information corresponding to the plurality of endpoints further comprises:
broadcasting registration information from the first endpoint to one or more other endpoints of the plurality of endpoints; and
receiving at the first endpoint registration information from the other endpoints of the plurality of endpoints;

storing the registration information in a routing table at the first endpoint;
locating a callee endpoint of the plurality of endpoints using the routing table in order to establish a session with the callee endpoint;
intercepting an endpoint state process of the session at a feature interaction point; and
determining a next state of the endpoint state process according to a feature finite state machine corresponding to the feature interaction point;
determining whether the event occurs; and
if the event occurs, accessing a web page stored on the first endpoint to determine whether the web page includes the event handler for the event and responding to the event according to instructions within the event handler stored on the first endpoint.

2. The method of claim 1 , wherein:
the first endpoint comprises a primary endpoint; and
the plurality of endpoints comprises a secondary endpoint operable to provide the proxy server feature if the primary endpoint fails to provide the proxy server feature.

3. The method of claim 1 , wherein:
the first endpoint is operable to provide the proxy server feature to one or more other endpoints of the plurality of endpoints; and
receiving registration information corresponding to the plurality of endpoints further comprises:
instructing the other endpoints to register at the first endpoint.

4. The method of claim 1 , wherein:
the first endpoint is operable to provide the proxy server feature to one or more other endpoints of the plurality of endpoints; and
locating the callee endpoint of the plurality of endpoints using the routing table further comprises:
receiving an invite message from a caller endpoint of the other endpoints; and
locating the callee endpoint in response to receiving the invite message.

5. A method for providing a proxy server feature, comprising:
initiating a proxy server feature at a first endpoint of a plurality of endpoints, wherein each endpoint of the plurality of endpoints is operable to provide the proxy server feature, and wherein initiating the proxy server feature at the first endpoint of the plurality of endpoints further comprises:
accessing feature logic using a service framework at the first endpoint, the feature logic stored on the first endpoint operating as the proxy server, the feature logic defining the proxy server feature and an event handler that indicates a response to an event; and
initiating the proxy server feature by executing the feature logic stored on the first endpoint;

receiving registration information corresponding to the plurality of endpoints, the registration information corresponding to an endpoint comprising an address for the endpoint, and wherein receiving registration information corresponding to the plurality of endpoints further comprises:
receiving at the first endpoint registration information from a second endpoint of the plurality of endpoints; and
providing the registration information to a third endpoint of the plurality of endpoints;

storing the registration information in a routing table at the first endpoint;
locating a callee endpoint of the plurality of endpoints using the routing table in order to establish a session with the callee endpoint;
intercepting an endpoint state process of the session at a feature interaction point; and
determining a next state of the endpoint state process according to a feature finite state machine corresponding to the feature interaction point;
determining whether the event occurs; and
if the event occurs, accessing a web page stored on the first endpoint to determine whether the web page includes the event handler for the event and responding to the event according to instructions within the event handler stored on the first endpoint.

6. A first endpoint of a plurality of endpoints, comprising:
a memory operable to store a routing table; and
a processor coupled to the memory and operable to:
initiate a proxy server feature, wherein each endpoint of the plurality of endpoints is operable to provide the proxy server feature, and wherein initiating the proxy server feature at the first endpoint of the plurality of endpoints further comprises:
accessing feature logic using a service framework, the feature logic stored on the first endpoint operating as the proxy server, the feature logic defining the proxy server feature and an event handler that indicates a response to an event; and
initiating the proxy server feature by executing the feature logic stored on the first endpoint:

receive registration information corresponding to the plurality of endpoints, the registration information corresponding to an endpoint comprising an address for the endpoint,
record the registration information in the routing table; and
locate a callee endpoint of the plurality of endpoints using the routing table in order to establish a session with the callee endpoint;
intercept an endpoint state process of the session at a feature interaction point; and
determine a next state of the endpoint state process according to a feature finite state machine corresponding to the feature interaction point;
determine whether the event occurs; and
if the event occurs, access a web page stored on the first endpoint to determine whether the web page includes the event handler for the event and respond to the event according to instructions within the event handler stored on the first endpoint, and

wherein the processor is further operable to receive registration information corresponding to the plurality of endpoints by:
broadcasting registration information from the first endpoint to one or more other endpoints of the plurality of endpoints; and
receiving at the first endpoint registration information from the other endpoints of the plurality of endpoints.

7. The endpoint of claim 6 , wherein:
the first endpoint comprises a primary endpoint; and
the plurality of endpoints comprises a secondary endpoint operable to provide the proxy server feature if the primary endpoint fails to provide the proxy server feature.

8. The endpoint of claim 6 , wherein:
the first endpoint is operable to provide the proxy server feature to one or more other endpoints of the plurality of endpoints; and
the processor is further operable to receive registration information corresponding to the plurality of endpoints by:
instructing the other endpoints to register at the first endpoint.

9. The endpoint of claim 6 , wherein
