Abstract

The present invention provides a method and apparatus for providing voice and data communications in a single connection. More specifically, the present invention monitors the phone call at the first device (108). The present invention then determines whether an outgoing component (signal between 306 and 312) of the phone call at the first device (108) is substantially silent and transmits the one or more data packets to the second device (102) via the outgoing component (signal between 306 and 312) whenever the outgoing component (signal between 306 and 312) is substantially silent. The present invention also determines whether an incoming component (signal between 310 and 304) of the phone call contains one or more data packets, and extracts the one or more data packets from the incoming component (signal between 310 and 304) whenever the incoming component (signal between 310 and 304) contains the one or more data packets.
