Abstract: A method for controlling or monitoring a common PBX phone line from a plurality of personal computer endpoints with multiple instances of application of a SIP soft phone application.

Abstract: A method and system for accepting invitations sent to multiple endpoints for an instant messaging participant is provided. The acceptance system allows multiple endpoints of a participant to be registered at the same time with an instant messaging service. The endpoint of the inviting participant sends an invitation to the instant messaging service indicating that the receiving participant is to be invited to establish a conversation with the inviting participant. When the instant messaging service receives the invitation, it detects that the receiving participant has multiple endpoints registered and forwards the invitation to each registered endpoint. When an endpoint receives the invitation request, it displays an information window asking whether the receiving participant wants to accept the invitation. Upon acceptance, the endpoint sends an acceptance to the endpoint of the inviting participant to establish the conversation between that endpoint and the endpoint of the inviting participant.

Abstract: Architecture that facilitates the conveyance of a trust level when the caller makes a call, the trust level in dependence on the state of the caller system. The callee (call recipient) receives notification of the trust level and can use this information in the communication such as to request verification from the caller and/or initiate other modes of communication. A caller can authenticate the caller identity in different ways to a communication server. Based on that, the server can assign an appropriate server-verified trust level to the caller. Further, an unsecured phone controller can indicate a lower client-side defined trust level. The server verified and client-side trust levels are then sent to the callee, where the callee determines whether to allow caller access to one or more secured features based on the feature values and the trust level imposed by the callee to access those features.

Abstract: A method and system for providing expanded presence information of publishers to subscribers is provided. The presence system receives expanded presence information from a publisher. A client component of the presence system sends the expanded presence information to a presence server of the presence system. Upon receiving the expanded presence information, the presence server stores the expanded presence information in association with the publisher. When the presence server is to provide the presence information of a publisher to subscribers, the presence server identifies the current presence state of the publisher and retrieves the expanded presence information. The presence server then provides the current presence state and the expanded presence information to the subscribers.

Abstract: Techniques for associating one or more real-time sessions, which are each signaled separately, into one logical conversation without a centralized control, are provided. Some techniques share a conversation identifier that uniquely identifies a logical conversation across the real-time sessions that belong to the logical conversation. The conversation identifier is generated before the first real-time session belonging to the logical conversation is signaled, and distributed to the other participants in the logical conversation via the signaling channel. A called participant can use the conversation identifier for associating the previous real-time sessions belonging to the logical conversation, and for making new invitations for other real-time sessions that are associated with the same logical conversation.

Abstract: A call forwarding system forwards telephone calls based on presence information of a user as reported by computing devices associated with a telephone number. When a telephone system receives an incoming call directed to one of the telephone numbers of the user's computing devices, it sends an incoming call event to each computing device. Upon receiving the incoming call event from a telephone system, each computing device determines whether the user is most likely present at that computing device based on the presence information. When a computing device determines that the user is most likely present at that computing device, it sends a notification to the telephone system to forward the incoming call to the telephone number associated with that computing device to effect the automatic forwarding of a call based on presence information.

Abstract: A method and system for providing context of a caller to a callee when a call is initiated is provided. The context system executing on the calling device collects context for the call. The calling device initiates the call and sends a message to the callee that includes the context. Upon receiving the message, the callee device notifies the caller that a call has been initiated and displays the received context. The callee can decide based on the received context whether to answer the call or not answer the call.

Abstract: In one embodiment, a user may transfer a multimodal conversation. A multimodal conversation may have a first mode communication session and a second mode communication session. A first user point of presence may execute a first transfer of the first mode communication session with a first partner point of presence from the first user point of presence to a first target point of presence. A second user point of presence may execute a second transfer of the second mode communication session with a second partner point of presence from the second user point of presence to a second target point of presence.

Abstract: A method and system for providing context of a caller to a callee when a call is initiated is provided. The context system executing on the calling device collects context for the call. The calling device initiates the call and sends a message to the callee that includes the context. Upon receiving the message, the callee device notifies the caller that a call has been initiated and displays the received context. The callee can decide based on the received context whether to answer the call or not answer the call.

Abstract: A muting system that allows audio of a computing device to be automatically muted when a telephone call is received on a telephone number associated with the computing device is provided. When an incoming call event occurs for that telephone number, the computing device directs a software component to mute the audio. When the muting system subsequently receives a call event indicating that the call has terminated, it may automatically un-mute or resume the software components. The muting system may allow a user to manually specify to un-mute or resume the software components.

Abstract: Techniques for transfer error recovery are described. A system may comprise a context generator module operative to record context information for a first call session between a first call terminal and a call system resource, and store the context information with a context identifier in a context table. The system may include a transfer error context module to couple to the context generator module, the transfer error context module operative to generate transfer error context information having the context identifier. The system may include a call transfer module to couple to the transfer error context module, the call transfer module operative to send the transfer error context information to the first call terminal for use in case of a transfer failure event. Other embodiments are described and claimed.

Abstract: Multiple instances of an incoming call in an integrated system capable of communicating through multiple networks are associated such that the called party is provided a single (merged) notification along with options to select among available call types. The call is established using a selected network and end device registered to the called user. Association of the instances is accomplished by comparing caller identity derived from a variety of information associated with the calling party. Conversation or correlation IDs are used to associate the instances as being for the same call and with other related communications such as a related instant messaging session.

Abstract: Context-based call routing is provided in a unified communication system by enabling subscribers to define a routing document, which is published by the communication system to callers who subscribe to a presence of the called party. Through publication of the context-based routing information, callers are enabled to make selections between call destination options as defined by the caller and provide a subject for the requested call. The call is then routed by the system according to the caller selection allowing efficient facilitation of the communication between the caller and the called party or their designees.

Abstract: The claimed subject matter provides a system and/or a method that facilitates authenticating a data communication. An interface component can receive data related to a real time data communication between two or more clients. A verification component can employ a human interaction proof (HIP) to a client participating within the real time data communication, wherein a human identity of the client is authenticated as a function of a response to the HIP.

Abstract: A notification system, upon receiving an indication of an event, determines whether the user has requested to suppress event notifications. When the user has requested to suppress event notifications, the notification system suppresses the event notification by not notifying the user of the event. When the user has not requested to suppress event notifications, the notification system infers whether the user wants to suppress event notifications. When the notification system infers that the user does not want to suppress event notifications, the notification system provides to the user a normal event notification. When the notification system infers that the user does want to suppress event notifications, the notification system provides to the user a modified event notification.

Abstract: A facility for integrating data in conversations is provided. In various embodiments, the facility sends a first message to a responding computing device to begin a conversation, receives a second message associated with the conversation from the responding computing device, determines whether the received message contains an indication of data that is to be associated with the conversation and, when the received message contains an indication of data that is to be associated with the conversation, renders the data. The facility can comprise an application server that receives from an initiator a first message associated with a conversation and responds to received messages, a conversation component that handles messages associated with the conversation, and an integration component that determines whether there is data that is to be associated with the conversation and, if so, adds an indication of the data to a second message that it sends to the initiator.

Abstract: A client-side signaling mechanism that allows a client to control how a telephone call is handled on a call server. The client user can create call routing rules on the client device using a client control component that manages session protocol messages. Once created, the call routing rule(s) created on the client are transmitted to the call server where a call routing component of the call server processes the rule(s) for a call related to the client. When the server receives the rule(s) and determines that the rule(s) are related to an existing call (incoming or currently in-process), the server halts current normal server rules processing for that call and executes the client-created rule(s). In one example, SIP session messages are employed for client control of server-side call forwarding.

Abstract: A presence aggregation system provides a presence aggregation server that allows for the publication of presence state of a publisher from the publisher's multiple endpoints. A presence state includes an availability value and an activity. An activity may include an activity token and/or a custom string. When any one of the publisher's endpoints makes a presence state publication on the presence aggregation server, the presence aggregation server generates an aggregated state of the publisher (i.e., the availability of the publisher aggregated across all of the publisher's endpoints) and publishes the generated aggregated state to each of the publisher's endpoints. The presence aggregation server may also provide the publisher's aggregated state to the subscribers of the publisher's aggregated state information.
