In this report, we examine the possibility of transmitting data on the GSM full rate voice channel. We conclude that the goal is achievable in principle, but that it requires too much processing power. We also examine the transmission of V.23 signals through the encoder-decoder chain and show experimentally that they cannot be distinguished reliably.
