摘要： An architecture for an extensible real-time collaboration system is provided. The architecture presents a unified application program interface for writing application programs that use communications protocols. The architecture has activity objects, endpoint objects, and multiple media stacks. These objects may use various communications protocols, such as Session Initiation Protocol or Real-Time Transport Protocol to send and receive messages. The activity objects, endpoint objects, and multiple media stacks may each have one or more APIs that an application developer can use to access or provide collaboration-related functionality. These objects map the API to the underlying implementation provided by other objects. Using the activity objects enables a developer to provide less application logic than would otherwise be necessary to provide complex collaboration services.

摘要： A method and system is provided to integrate the Kerberos security mechanism into the message flow of the signaling operation under the Session Initiation Protocol to allow a SIP client and a SIP proxy to authenticate each other. When the SIP proxy receives an request message, such an INVITE request, from the SIP client, it responds with a challenge message indicating that authentication based on Kerberos is required.In response, the SIP client sends a second request message with a proxy authorization header containing authentication data, including a Kerberos server ticket for the Proxy, to allow the proxy to authenticate the client's user.

摘要： 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.
摘要翻译：客户端信令机制，允许客户端控制如何在呼叫服务器上处理电话呼叫。客户端用户可以使用管理会话协议消息的客户端控制组件在客户端设备上创建呼叫路由规则。一旦创建，在客户端上创建的呼叫路由规则被发送到呼叫服务器，呼叫服务器的呼叫路由组件处理与客户端相关的呼叫的规则。当服务器接收到规则并确定规则与现有呼叫（传入或正在进行中）相关时，服务器将暂停针对该呼叫的当前正常服务器规则处理，并执行客户端创建的规则（s）。在一个示例中，SIP会话消息用于服务器端呼叫转发的客户端控制。

摘要： 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.

摘要： A system for detecting and communicating the presence of one or more computing devices is presented. The invention also presents a method and system for aggregating presence information generated by multiple devices associated with a single user. A server acting as a presence agent on behalf of a first user receives and responds to a subscription request generated by a computing device operated by a second wishing to be permitted as a watcher of the first user. When the second user corresponds to access preferences of the first user, a notify message is sent to the second user's device that includes presence information indicative of an activity level and availability level associated with the first user. When the first user employs multiple computing devices, the server generates an aggregate presence document that is representative of the overall presence of the first user.

摘要： A method and system for establishing a connection with a server after a connection has been broken is provided. A connection system in a service layer of a client detects that a connection between the client and the server has been broken. Upon detecting the broken connection, the connection system of the service layer automatically attempts to re-establish an application-level connection to the server. If the connection system can re-establish an application-level connection to the server, then it need not notify the application layer of the broken connection.
