Abstract: Call control messages and audio signals between a telephone device and a computer network telephone client on a computing device can be intercepted. For control messages from the computer network telephone client, the control messages can be translated from a first control protocol to a second control protocol and forwarded to the telephone device. For control messages from the telephone device, the control messages can be translated from the second control protocol to the first control protocol and forwarded to the computer network telephone client. For audio signals from the computer network telephone client, the audio signals can be translated from a first audio protocol to a second audio protocol and forwarded to the telephone device. For audio signals from the telephone device, the audio signals can be translated from the second audio protocol to the first audio protocol and forwarded to the computer network telephone client.

Abstract: A method and system for managing presence information based on collections of publications is provided. The presence system creates collections of publications for a publisher. A publication includes a type and value. A publisher may define one collection of publications that is to be made available to certain subscribers and another collection of publications that is to be made available to other subscribers. The presence system may allow a publisher to update individual publications within a collection. Moreover, the presence system may identify subscribers of a collection at the time of subscription.

Abstract: A method and system for increasing the computational and network efficiency of presence servers having collections of publications is provided. The presence system uses several techniques that enable a presence server to provide rich presence information without requiring expensive processing. First, the presence system accepts batches of publication updates in a single presence update request. Similarly, the presence system accepts batches of subscription requests. Next, the presence system supports new expiration types for publication update requests that eliminate the need for a publishing user to continually refresh presence information that has not changed. Finally, the presence system accepts access lists that contain membership groups rather than an individual list of users that are to have access to a particular presence collection.

Abstract: 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.
