Abstract: The present invention provides a full-featured telecommunications system without the cost and infrastructure requirements of conventional private branch exchange (PBX) systems. A system according to aspects of the present invention comprises a data processing unit and an application controller in communication with the data processing unit. The application controller comprises a processor, a user interface, and a memory coupled to the processor. The memory stores instructions that, when executed by the processor, cause the processor to receive a request for a communication through the data processing unit and instruct the data processing unit to perform the communication in accordance with the request.

Abstract: The present invention provides a data processing unit that provides elements of a full-featured telecommunications system without the cost and infrastructure requirements of conventional private branch exchange (PBX) systems. A system according to various aspects of the present invention comprises a processor, a data interface, a wireless transceiver, and a memory coupled to the processor. The memory stores instructions that, when executed by the processor, cause the processor to receive information pertaining to a wireless communications format through the data interface, configure the wireless transceiver to communicate in the wireless communications format, and perform a communication, using the wireless transceiver, in response to a request for a communication received through the data interface.
