Provided herein are system and methods whereby a speaker in a webconference may take control of a pointer that is visible to other participants of the webconference. Speaker detection identifies the speaker, or 'active talker,' and then provides, or offers, pointer control to the detected speaker. The speaker may then be able to utilize their client device's input device, such as a mouse, touchpad, or other pointer control mechanism to control a common pointer visible to the other participants of the webconference. The a host of the webconference maintains control of the other aspects of the webconference, as well, administrative control of the pointer and may, for example, rescind pointer assignment given to a particular 'active talker.'

Active talker activated conference pointers

A communication device sends a Session Initiation Protocol (SIP) INVITE message to establish a call. In response, the call is forked. For example, in parallel forking, the SIP INVITE may be sent to two different communication devices. The forking causes each communication device to send at least one provisional response message. In this case, first and second SIP provisional response messages are received that include Session Description Protocol (SDP) information for a media stream. A first media stream associated with one of the first or second SIP provisional response messages is received and played. A second media stream associated with the other one of the first or second SIP provisional response messages is received within a first time period. In response to receiving the second media stream within the first time period, the first media stream is discarded and the second media stream is played.

Early media handling

In order to deal with multiple communication endpoints that use a single address of record (e.g., a telephone number), a list of friendly names is determined for the multiple communication endpoints. The friendly names identify individual communication endpoints. For example, a friendly name may be 'Joe's Desktop.' When a Computer Telephone Integration (CTI) application is associated with a communication session, the list of friendly names is presented to a user. The user selects one of the friendly names. This results in a message being sent that indicates a communication endpoint associated with the selected friendly name. The message with the friendly name causes a new communication session to be automatically initiated from a communication endpoint associated with the selected friendly name or an answer of a forked communication session with the communication endpoint associated with the selected friendly name.

Methods and systems are provided such that users, servers, and applications may utilize an extensible data filtering model where data is organized into a tree with filtering available at any node level. Accordingly, the node filtering and propagation method and system allows for the efficient management and automatic replication of common information for multiple applications at all data levels.

Method, apparatus, and system for providing and using subscriptions and filtering based on tree structures

A communication system, method, and components are described. Specifically, a communication system having the ability to carry a transitive context and communicate the transitive context to new participant user agents for continuity through all related call dialogs is disclosed. The transitive context communication is possible through the use of a newly created SIP dialog using a REFER message and/or an INVITE message for all call flows and topology change operations.

Call context conveyance

To provide better administrative access control for allowing access to network applications, an authorization framework is extended by dynamically adding administrative access control to the authorization framework. For example, the authorization framework can be extended by adding a plug-in to the authorization framework. The authorization framework manages the access control by generating tokens. For example, a token may be a digital certificate. The tokens define what access control an application, such as a client application has when accessing the network application. The tokens are based on the dynamically added administrative access control. When a request for a token is securely received, the authorization framework generates a token that identifies if the application (e.g., the client application) is allowed or not allowed to access the network application. The token is then used by the application to access the network application.

Extension of authorization framework

A first Session Initiation Protocol (SIP) REFER message is sent by an application server to a User Agent (UA). A UA is typically in a communication device, such as a telephone or personal computer. The first SIP REFER message requests the UA to provide a unique Uniform Resource Identifier (URI) for an instance of a networked application. For example, a networked application may be a call recording application. In response to sending the first SIP REFER message, a SIP NOTIFY message with the URI for the instance of the networked application is received by the application server. The application server sends a second SIP REFER message to the UA using the URI. The second SIP REFER message includes information for managing a widget. A widget is object, such as a button or sound. The widget is then displayed or played on a communication device according to a set of rules.

Pushing graphical user interface widgets for communication devices

An indication of a change in a right to use a service or feature is received. For example, this can be based on an administrator granting access to a previously installed service or feature. In response, a notification is sent to a user of the change of the right to use the service or feature. The notification requests the user to provide a credential to approve the change of the right to use the service or feature. For example, a link may be provided in an email or text message that the user can click on to provide a password/user name. The credential is received and verified. In response to validating the credential, access is allowed according to the change of the right to use the service or feature. The user then has access to the service/feature without the administrator having to know the user's credential.

Adding features and services without password exposure

The concept of chained parallel forking is introduced. Addresses of record are included in a contactee's contact resolution preferences to enable an incoming INVITE message to be routed to one or more users as well as other devices, per the contactee's contact resolution preferences. A communication system configured to execute the chained parallel forking contact resolution process is also described.

Parallel forking with AoR chaining

Methods and systems for providing an elegant and efficient multi-protocol eventing layer are disclosed. The multi-protocol eventing layer includes a converged container capable of handling multiple types of protocols to manage events while using an open source database. Accordingly, the multi-protocol eventing layer efficiently provides real-time or near real-time eventing to a plurality of devices for scalability and performance enhancement.

Method, apparatus, and system for providing and using multi-protocol eventing

Systems and methods are described for creating and managing Global Session Identifiers (GSIDs) for communication sessions. GSIDs provide a way to globally identify communication sessions including those communication sessions that have experienced one or more topology changes. The GSID may be considered a header itself or a value within a header and information contained within a GSID can be used to trace backwards through time to find the session segments that led up to (or exist concurrently to) a currently signaled session.

Global session identifier

Methods and systems are provided that utilize the functionality of an end user device in binding a virtual desktop infrastructure (VDI) media client on an end user device with a VDI host client on a VDI server. In particular, the native operating system (OS) on the end user device may take a screen-shot of a quick response (QR) code displayed to a graphical user interface of the end user device. The end user device may provide information associated with the screen-shot of the QR code to a collaboration server where the collaboration server binds the VDI media client together with the VDI host client upon verifying the information associated with the screen-shot of the QR code.

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 application. Such a communication log application 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.

The concept of a secure call indicator is introduced. In general, the secure call indicator is capable of inspecting the security of signaling associated with Session Initiation Protocol (SIP) messages and comparing the security with media descriptions of the actual media path of the SIP messages. Furthermore, the secure call indicator may be configured to indicate the security associated with a communication session via a physical or virtual notification system.
