Abstract: A non-transitory computer-readable medium can include instructions for performing a method that includes docking a mobile device with a docking station using at least one physical connection and at least one wireless connection to provide communication between the mobile device and the docking station. One of the physical or wireless connections can be selected for providing a signaling channel for communication of signaling data between the mobile device and the docking station. Independently of the signaling channel, one of the physical or wireless connections can be selected for providing a media channel for communication of media data between the mobile device and the docking station.

Abstract: A telephony system is presented that enables a phone to access a directory and use the directory in conjunction with other phone functions. The system includes a server with a telephony management software (TMS) unit, a telephony application programming interface (TAPI) unit, and an application unit. The application unit includes a control module, a function module, a filter module, a presentation module, a phone interface module, and a storage interface module. A server sends a signal to a phone regarding the contents of a directory. A server also enables a user to navigate through the directory, filter the directory, and perform call functions on phone numbers associated with directory entries.

Abstract: A client application server (CAS) can include a presence layer configured to compute a published presence state for a client of the given CAS that characterizes at least one of an ability and a willingness of the client to communicate with another communication endpoint. The presence layer can also be configured to provide the published presence state for the client to a presence layer of at least another CAS according to a subscription request provided from the another CAS.

Abstract: Session-based data, such as call detail accounting information, is tracked and distributed to a plurality of servers in a distributed telephony environment. One type of session is a telephone call between participants. Session-based data includes information about a session provided by the switches along the media path. Session-based data further includes information related to the session obtained from the application layer (e.g., user input metadata). A network proxy maintains a participant list to which the session data is distributed. The network proxy sends updates to the participants and determines the network status to implement fault tolerance of data distribution.

Abstract: A system for providing voice mail backup on a secondary server including two or more distributed voice mail servers. Each distributed voice mail server includes a telephony management software (TMS) unit, a telephony application programming interface (TAPI) unit, and an application unit. The application unit includes a voice mail control module, a call status module, a call transfer module, a voice mail migration module, a storage module, an audio encoding/decoding module, a configuration module, an extension library module, and a telephony application programming interface (TAPI) interface module. Each server is capable of storing a voice message for an extension serviced by a remote server if the remote server is unavailable.
