Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method provides for concurrent sessions to be maintained by multiple endpoints.

Abstract: An improved system and method are disclosed for providing voice call continuity in an enterprise network. For example, an enterprise public branch exchange (PBX) may be configured with a pilot number that is used to provide VCC services when called by a client. Digit collection via DMTF signaling or other means may be used to collect destination information from the client. The enterprise network may use the collected digits to establish a communication session with another device that corresponds to the destination information.

Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method enables an endpoint to sweep an ongoing communication session to another endpoint by transferring session information between the endpoints.

Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method enables the creation of a virtual endpoint that may operate within a peer-to-peer network to represent a device that is unable to operate as an endpoint.

Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method enables an endpoint to transfer data directly to another endpoint.

Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method enables two endpoints to dynamically select one of multiple possible routes for inbound and outbound messages.

Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method enables an endpoint to use a tunneling server to bypass a network address translation (NAT) device that is blocking messages to an endpoint on the other side of the NAT device.

Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method includes retrieving a profile and a routing table from an access server by a first endpoint during an authentication process. The profile identifies at least a second endpoint as an endpoint with which the first endpoint has permission to communicate. The routing table contains address information needed for the first endpoint to communicate directly with the second endpoint. The first endpoint sends a notification message directly to the second endpoint using the address information to inform the second endpoint that the first endpoint is online.

Abstract: An improved system and method are disclosed for peer-to-peer communications. In one example, the method is for connecting an endpoint that is separated from another endpoint by a symmetric network address translation device.

Abstract: A system and method for endpoint handoff in a hybrid peer-to-peer networking environment are provided. In one example, the method includes logging into the peer-to-peer network by a first endpoint. The first endpoint directly notifies a second endpoint that the second endpoint is to transfer an active communication session existing between the second endpoint and a third endpoint from the second endpoint to the first endpoint. The first endpoint receives session parameters associated with the active communication session directly from the second endpoint and directly notifies the third endpoint that the first endpoint is online. The first endpoint then re-establishes the active communication session with the third endpoint using the session parameters.

Abstract: Provided are a system and method for network transitions. In one example, the method includes receiving messages from a mobile device indicating that the mobile device is in a session initiation protocol (SIP) wireless hotspot and that the mobile device is engaged in a communication session via a cellular network while in the SIP wireless hotspot. The cellular network is instructed to add the mobile device to the communication session via the SIP wireless hotspot. An affirmative response is received from the cellular network and a third message is sent to the mobile device to notify the mobile device of the affirmative response.

Abstract: Provided are a device and method for maintaining a communication session during a network transition. In one example, the method includes monitoring, by a client, a connection with a first network to determine whether a signal strength of the connection falls below a threshold value. The client establishes a connection with a second network if the signal strength of the connection with the first network falls below the threshold value. Establishing the connection with the second network includes obtaining an address and port assignment corresponding to the client from the second network. The client uses the obtained address and port assignment to maintain a communication session during the changeover from the first network to the second network.
