Abstract: A communication system is provided that uses loosely-coupled client-server architectures to improve the efficiency of communications. The communication system includes client and facilitator applications. The client application is a component of processor-based mobile communication devices. The facilitator application is hosted on one or more servers or other processor-based devices, and communicates with the client application via one or more couplings. The facilitator application can also be distributed among one or more portable processor-based devices including the communication devices hosting the client application.

Abstract: Communication systems and methods are described that include class-based call request routing. Components of the communication systems are configured to receive information of a class at a calling device. In response to the class information, a call request is automatically generated and addressed to resources of a class group. The resources of the class group all possess a common attribute of the class. The attribute includes one or more of a skill, job specialty code, job title, company, department, and division. The generated call request is routed to target devices of the resources. In response to a resource accepting the call request, a response message is received from a target device of the resource. Communications are established between the calling device and the at least one target device in response to the response message received from the target device.

Abstract: A conversation-based user interface (UI) is described. The presenting of the UI includes receiving communications from numerous people. The communications include media that is electronic. A conversation list is generated that includes conversation information of each of the communications. The conversation information includes information of a sender and the media of each communication. The conversation list is displayed.

Abstract: Embodiments for generating a sorted integrated directory are described. The sorted integrated directory integrates contacts from disparate directories into a common directory. The formation of the integrated directory includes receiving contacts from multiple directories. The contacts represent or are formed under multiple data structures, with one data structure corresponding to one of the directories. The received contacts are converted into contact objects. The contact objects, each of which represents a contact, all include or are formed under a common data structure. An integrated directory is generated or formed from the contact objects. The integrated directory thus includes a set of contacts of the disparate source directories.

Abstract: Communication systems and methods are described that enable mobile devices to route telephone calls via an enterprise telephone system. The communication system is configured to receive via a data channel a request from the mobile device. The mobile device corresponds to a user making a call. The server receiving the request includes a private branch exchange (PBX) and one or more other servers hosted by or coupled to the enterprise. A first call leg is initiated over a first voice channel in response to the request. The first call leg is coupled to the server and mobile device. Numerous second call legs are initiated over a second voice channel, and the second call legs are coupled to the server and numerous client devices corresponding to an intended call recipients. A voice conference call is formed between the mobile device and client device by joining the first and second call legs.

Abstract: Embodiments for searching multiple directories are described. The searching includes remote searching and local searching. Local searching is performed against the local integrated phonebook on a client device. In contrast, remote searching is performed against one or more directories or directory types of an enterprise server (e.g. corporate directory, etc.). The local directory on the client device therefore effectively functions like a cache of information of one or more of the directories of the enterprise server, where the cache is stored locally on the client device.

Abstract: Melting information of a client device is described. The device melting includes receiving a melt message at an inbox of a client device. A source of the melt message is authenticated using identification information of the melt message. The client device automatically deletes client state information of the client device in response to authenticating the source of the melt message.

Abstract: Communications rate control is described. The rate control includes receiving a message addressed to a client device of a user. A determination is made as to a category of the message. Data of the message is synchronized between a server and the mobile device in response to one or more of the category and one or more user actions at the client device.
