Abstract
A method for communicating data during an audio conference is provided. Digital data is received from a data source. The digital data is then modulated onto a carrier signal. The modulated carrier signal is subsequently combined with an audio signal of the audio conference. The combined signal is communicated to at least one remote communication device. Upon receipt by the at least one remote communication device, the combined signal is separated into the audio signal and the modulated carrier signal. The modulated carrier signal is then demodulated to extract the digital data. Both the digital data and the audio signal are output by the at least one remote communication device.
