| 20110044184 | SWITCHING COMMUNICATIONS BETWEEN DIFFERENT NETWORKS BASED ON DEVICE CAPABILITIES - Methods and systems provided herein allow a communication session to be established on an optimal communication network and subsequently transferred to alternative networks if conditions dictate that such a change is necessary or desirable. The types of conditions which may be considered when identifying the optimal communication network or the alternative network include conditions related to the operation of a user device, communication profiles of the user, resources available on other networks, and the like. | 02-24-2011 |
| 20110066694 | SIP ENDPOINT ENHANCER - Methods, devices, and systems are provided for enhancing the functionality of a communication device, such as a communication endpoint. This provides the ability to enhance less intelligent SIP endpoints with required features to support a richer user experience. Furthermore, the endpoint enhancer may be dynamically pluggable onto an existing network device. This provided pluggability allows a network administrator to add a new SEE template to the network without disrupting the network operation or the operation of previously existing SEEs. | 03-17-2011 |
| 20110081013 | Shared Media Access for Real Time First and Third Party Media Control - A method comprising a data-processing system that enables one or more applications to share fewer ports by having the data-processing system request the ports, and then assign a “token” to establish a “session” to permit the one or more applications to interact with the ports. | 04-07-2011 |
| 20110289203 | SIP MONITORING AND CONTROL ANCHOR POINTS - The concept of anchor points is introduced. Anchor points, and specifically Session Initiation Protocol (SIP) anchor points, serve as a media and call control point that is established on a per-user basis which can then be shared by any application. The use of an anchor point allows for applications to become aware of and control a communication late or cease monitoring and controlling a communication session early without disrupting the session or introducing a significant amount of control or media delay. | 11-24-2011 |
| 20110289219 | SIP ANCHOR POINTS TO POPULATE COMMON COMMUNICATION LOGS - The concept of a centralized communication log is provided. Anchor points, and specifically Session Initiation Protocol (SIP) anchor points, serve as a media and call control point that is established on a per-user basis which can then be leveraged by a communication log service. Such a communication log service is able to determine accurate and real-time communicant information for a communication session and populate a centralized communication log with the same. Such a communication log is, therefore, accurate with respect to multiple users in a system, highly available, and scaled horizontally. | 11-24-2011 |
| 20120163571 | HIGHLY SCALABLE AND DISTRIBUTED CALL/MEDIA MODELING AND CONTROL FRAMEWORK - A highly scalable and distributed call/media modeling and control framework is described. In particular, a plurality of anchor point servers are provided which enable one or more applications to exert call and media control over in-progress communication sessions even though the applications were not originally bound to the communication session during its setup. | 06-28-2012 |
| 20120265808 | CONTEXTUAL COLLABORATION - An activity stream is created in a first medium. The activity stream is a mechanism where participants can collaborate on a subject. Participants are added to the activity stream. A participant in the activity stream initiates a communication in a second medium. The status of the communication is determined. If the status of the communication is active, the status of the communication is indicated in the activity stream. | 10-18-2012 |
