1. A system for providing secure communications over a network, the system comprising at least two communication devices, each including:

  • a processor;

    a security device coupled to the processor;

    a digital port being coupled to the processor;

    a conversion device operable to convert between digital data and audio and being coupled to the processor;

    an audio port coupled to the conversion device;

    a memory coupled to the processor; and

    code being stored in the memory and executable by the processor to;

    selectively establish a point-to-point communication between first and second ones of the communications devices across the network via at least one cellular communications portion of the network so as to effect a secure exchange of data by encrypting data and decrypting data to be transmitted and received, respectively; and

    selectively communicate data from the conversion device of the first communications device and indicative of audio received at the audio port of the first communications device across the point-to-point communication via the digital port of the first communications device to the conversion device of the second communications device, where it is converted to audio provided at the audio port of the second device.
