20100118742 | System and Method for Monitoring Call Flow in Heterogeneous Environments - The call states of all devices in a call are monitored and reported even when the devices belong to networks that use different types of call identifiers. A first device and a second device are different types of devices selected from a group of types comprising: a legacy device type, a SIP basic device type, and a SIP advanced device type. In response to a request-from an application to monitor the first device and a request to establish a call between the first device and the second device, a Universal Call Identifier (UCID) is generated for the call and the call is established. A request to monitor the second device is sent using the UCID. When a change in the call state of the second device is detected, the change of the call state is reported to the application based on the UCID. | 05-13-2010 |
20130173812 | SIP TRANSFER IN A BACK-TO-BACK USER AGENT (B2BUA) ENVIRONMENT - The system generates a change in the SIP INVITE message during a call transfer. Here, a user relation element involved in the call can change the header information in the message to include the endpoint view of the transferring party. Thus, the INVITE message is redirected to the transferring party's user relation element, which can interpret the received message and “unravel” the B2BUAs in the existing call path. The system includes changes in the user relation element to effect the message change and interpret the message once received. Changes to the user relation element forgo the need to change the communication endpoints. | 07-04-2013 |
20130254302 | SUPPORTING INTERMEDIATE BACK TO BACK USER AGENTS BETWEEN USER AGENTS AND A CONFERENCE FOCUS - A communication system, method, and components are described. Specifically, a communication system having one or more Back-to-Back User Agents (B2BUAs) therein is described. The communication system also includes an RFC 4579 conference focus. Mechanisms are described which enable User Agents (UAs) to subscribe to conference state events and create ad-hoc conferences even though the conference focus is operating in a B2BUA environment. | 09-26-2013 |
20140047122 | HIGH AVAILABILITY SESSION RECONSTRUCTION - A first message is received at a primary container that is replicated by a secondary container. The first message is an initial message to initiate a first session. The first message is processed by an application in the primary container. At a point in time, the primary container is unavailable and the system and method detect that the primary container is unavailable. A second message is received. The second message is associated with the first session. The second message is modified by moving at least a portion of a header in the second message into a different header in the second message and adding an additional header to the second message in response to the primary container being unavailable. | 02-13-2014 |
20140095723 | BYPASSING OR REDIRECTING A COMMUNICATION BASED ON THE FAILURE OF AN INSERTED APPLICATION - The system and method allow enhanced capabilities for Session Initiation Protocol (SIP) dialogs (communication sessions) between SIP devices. The SIP dialogs have applications that are inserted into the SIP dialog such as a Back-to-Back User Agent (B2BUA) or a proxy application. After the initial dialog is established and these applications fail or become unavailable, the system and method allow the applications to be bypassed or have the SIP dialog redirected to an alternative application. This provides a better user experience because the SIP dialog (e.g., a SIP telephone call) will not be dropped if the application fails mid-dialog. | 04-03-2014 |

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 |

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 |

The hot-desking application can be provisioned as an explicit sequenced application for all user addresses of record in addition to being provisioned as an implicit sequenced application for all of the possible hot-desk endpoint addresses. Through such provisioning, the hot-desking application can, among other things, allow for calls to be placed directly from a hot-desk endpoint but still show the user's address of record as the calling identity. | 03-27-2014 |
