Abstract: A unified session detail records of a multi-hop session is provided. The multi-hop session may be established through multiple nodes in a VoIP network. Each node may generate session detail records for the legs of the multi-hop session that are connected to the node. The nodes on the path of the multi-hop call may send the record to a single node to consolidate the session detail records of the legs of the multi-hop call in the single node so that the single node can provide unified session detail records of the multi-hop session. By providing unified session detail records, the user does not need to track down the nodes that are on the path of the multi-hop call to obtain the session detail records of the multi-hop session.

Abstract: The present invention enables testing of a VoIP network using various instrumented test streams. The testing can determine the quality of the transmission network before an internet VoIP service is put into production. The testing also enables regular diagnostic audits of a VoIP network to maintain the quality of the VoIP network. The testing enable measurement of, for example jitter, packet loss and delay and allow characteristics of the VoIP network to be obtained. In addition, the present invention can to determine the capacity and utilization of a VoIP transport network. Based on the measurements and characteristics of the VoIP network the present invention can control routing of a call on the VoIP network or can prevent a call from being made. The present invention also enables dynamic switching of CODECS during a session to enhance the performance of the VoIP network.

Abstract: A mechanism for managing and enhancing communication streams in a VOIP service using SIP is discussed. SIP is used to manage and enhance a communication stream at a centralized switching element in the VoIP environment rather than at the communication stream endpoints. The communication stream set up by SIP is directed through a central switching element under administrative control rather than traveling directly between the stream endpoints. As a result, the media stream may be conditioned with treatments and may be provided with enhanced services at the central switching element without the specific treatments and services being supported at both stream endpoints. The use of the centralized switching element allows full administrative control of the VoIP environment.

Abstract: The present invention provides in one aspect a method and a system for displaying a VoIP quality to a user, so that the user may determine if a specific call should be placed in view of the VoIP quality. The present invention also provides in another aspect a method and a system for non-intrusively signaling of an incoming VoIP call so that a user can be informed of the incoming call and yet not be interrupted from his/her current work.

Abstract: Some embodiments of the present invention provide a method and system for correlating information regarding an interactive communication. A session application record is provided to store information of a session that represents an interactive communication that is at least between two endpoints. An application programming interface (API) is provided for users to create and manipulate session application records. Application specific data or customized data can be stored with the session application record using a tag that includes a name and value pair. One session application record can be associated with another session application record by using a relation. Any information that is gathered during a session can be accessible even when one of the endpoints is replaced by another endpoint.

Abstract: The illustrative embodiment of the present invention provides a find-me service for VoIP. The find-me service allows a user to specify multiple communication devices. Further, the find-me service allows a callee to assign a priority to each communication device specified or in the alternative allows the calle to place the specified communication devices in prioritized lists. Multiple communication devices can have an identical priority level or can be placed in the same priority list. When the user is called, the call is processed by a software based call manager that initiates the find-me service. The call manager sends the call to all of the communication devices with the highest priority. This allows a single call to be sent to multiple communication devices simultaneously. If there is no answer at any of the communication devices the call manager sends the call to all of the communication devices on the list with the next sequential priority level.

Abstract: A mechanism for managing software modules in a VOIP service is discussed. A component management agent is provided for each VOIP software component in the VOIP environment. The component management agent registers with a session management agent which is in communication with a session management software facility. The component management agent accepts registrations from each software module in the component that it represents. The software module registrations indicate the type of objects that the software module supports. Subsequent managed object requests received from the session management facility are automatically directed to the appropriate software modules based on the registration information. Additionally, the session management agent and component management agent perform format conversions for the managed object requests where the session management facility and software modules are utilizing different object systems.

Abstract: A remote plug-in framework is provided in a VoIP (Voice over Internet Protocol) environment. One or more remote plug-ins may communicate with the call control engine of the VoIP environment. The remote plug-ins may provide a customized call processing logic so that a user can implement a customized call processing logic or add new services to the VoIP environment without changes in the call control engine of the VoIP environment. In an embodiment, the remote plug-ins may be provided using Web services.
