1. Software code stored on computer-readable memory and executable on a processor for communicating digital data over a voice channel of a digital wireless telecommunications network comprising:

  • code for forming the digital data into a packet payload in an inband signaling packet;

    code for attaching preconditioning bits to the inband signaling packet that prevent circuitry in the wireless telecommunications network from corrupting the digital data;

    code for converting the bits in the inband signaling packet into a series of voice frequency tones that simulate characteristics of human speech; and

    code for converting the simulated voice frequency tones into encoded data transmitted over the digital voice channel of a wireless telecommunications network.
