Abstract
A method and system for allowing multiple application programs to communicate in the context of a switched voice and data communication. The method includes providing a communication interface between multiple application programs and a router module in a sending and receiving system, and then using the router module to format data from one or more application programs into a single data block. During a brief interruption of the voice portion of the call, the sending system transfers the data block to the receiving system where the data block is interpreted and then routed to corresponding application programs. The system includes a router module to format data, a communication interface to couple applications to the router module, a communication port to transfer data over a phone line, through a communication device and a call manager module for performing line control.
