User-preference information is utilized in conjunction with a conference bridge for the purpose of customizing the receiving of text data, alerts, or other associated information. These settings can be stored in a media file, or a set of data that is kept on an endpoint, such as a conference-enabled endpoint or it can be a configuration of data maintained by one or more conference bridges. This user preference information can specify various preferences such as language, font, phone capabilities, phone number associated with a conference, video conferencing capabilities, preferences for rendering images, multi-media content preferences, whiteboard resolution, volume, and in general, any preference associated with any application or data associated with a conference.

Provided are methods, devices, and systems for maintaining a SIP survivable network. A SIP endpoint maintains an ordered list of the controllers that are available to it and registers with a subset containing the first N controllers in the list, where N is a plurality, but not all, of the controllers in the list, and obtains services from one or more of the controllers of the subset. If one of the controllers of the subset becomes unavailable, the endpoint registers with the (N+1)controller in the list, thereby adding it to the subset. If and when the one controller becomes available again, the endpoint de-registers with the (N+1)controller, thereby removing it from the subset, and if necessary re-registers with one controller. The subset thus forms a sliding window on the list.

Registering an endpoint with a sliding window of controllers in a list of controllers of a survivable network

Provided are methods, devices, and systems for maintaining a SIP survivable network. The present invention is adapted to allow SIP endpoints or User Agents to discover and select the controller or controllers that the SIP endpoint will register with. Selection of the controller or controllers may be based upon the relative attributes of the controllers and the needs of the SIP endpoint.

Simultaneous active registration in a SIP survivable network configuration

Provided are methods, devices, and systems for maintaining a SIP survivable User Agent. The present invention is adapted to allow the User Agent to detect the status of the network, thus providing the User Agent to perform failover/failback operations. The User Agent may be adapted to determine the status of the network based on its own monitoring mechanisms and/or based on messages received from other network components.

Survivable phone behavior using SIP signaling in a SIP network configuration

Provided are methods, devices, and systems for maintaining a SIP survivable network. The present invention may utilize messages, such as SIP NOTIFY messages, to trigger various network components to failover and failback based on the determined status of the SIP network.

A method and apparatus are provided for analyzing a user's communication activity to determine presence patterns at one or more communication devices. A user's presence at one or more communication devices is monitored over time to detect at least one pattern of behavior indicating that a user is likely to be present at a given communication device during a particular time interval. Once a presence pattern is detected, a call that is destined for the user during the associated time interval can be automatically routed to the user at the given communication device. As a transition between each presence pattern is reached, i.e., when the user changes locations or devices, the probability of the user being present on one device decreases while the probability of the user being present on another device increases. According to another aspect of the present invention, the presence call processor can optionally send messages to multiple devices during these transitional times to ensure that the call is received by the intended recipient.

Method and apparatus for routing a communication to a user based on a predicted presence

A method and apparatus for dynamically and automatically configuring an endpoint device to a computer network of a network system. When the endpoint device, such as a computer or router, initially connects to a computer network, it is dynamically assigned or allocated a first unique network (IP) address, as by a DHCP (Dynamic Host Configuration Protocol) server. The allocation of the first network address is monitored and, in response to the monitored allocation, a connection between a configuration manager and the endpoint device is established. The class of the endpoint device is then remotely identified and appropriate configuration information stored in a configuration database is retrieved and utilized to automatically configure the endpoint device within the network system.
