The various embodiments described herein generally provide apparatus, systems and methods which facilitate the transmission of data between a client device and a remote device over a voice channel of a telephone network. More particularly, data from a client device is modulated into an audio signal using linear predictive coding (LPC) synthesis and transmitted to the remote device during a phone call. The remote device receives the audio signal and performs linear predictive coding (LPC) analysis to extract the transmitted data.
