Architecture for a scalable, pluggable multi-party, and distributed multimedia conferencing. A centralized policy and control conferencing component allows the seamless plug-in of different distributed media components (e.g., data, audio/video, messaging) to accommodate client participation in a conference session. The centralized conference control component includes the following: a conference notification service for accepting subscriptions to the conference state and notifying subscribers about changes to that state; a conference policy and roster control service for storing and manipulating conference policy and rosters; a security service for user authorization/authentication based on user identity information; a scheduling service for conference scheduling; an allocation service for allocating the most available media component(s) for a conference session; and, an MCU management service for conference policy and roster management of the distributed media components.

A facility for providing an IM mixed mode operation by utilizing both page mode IM and session based IM jointly in the same IM conversation is provided. The facility initiates an IM conversation between an originating user registered at an originating device and a remote user registered at a plurality of devices initially in page mode. Subsequent to discovering the identity of a remote device used by the remote user to initially reply to the IM conversation, the facility converts the IM conversation from page mode IM to session based IM.

Mixed massaging mode for multiple points of presence

A method and system for identifying whether an electronic communication is likely to be unwanted by the recipient is provided. A trust system relies on a trust provider, such as a sending domain, to indicate whether an electronic communication is likely to be unwanted. The sending domain may assign its trust level to the electronic communications based on various factors. Upon receiving the electronic communication and the trust level assigned by the sending domain, the receiving domain may determine whether to forward the electronic communication to the recipient based on the trust level. If a sending domain consistently provides trust levels that are accurate assessments of whether electronic communications are unwanted, then the receiving domain learns to trust the trust levels assigned by the sending domain. In contrast, if the assigned trust levels are not accurate, then the receiving domain learns not to trust the sending domain and may discard all message from the receiving domain without forwarding them to the recipients.
