Abstract: A method and exploration engine for automatically detecting a call flow path of a voice application having a plurality of dialog states, the method comprising the steps of: identifying, in an automated manner, the plurality of dialog states of the voice application through execution of the voice application; and identifying at least one relationship between the plurality of dialog states. The method may further comprise some of the following steps: creating a unique identifier (ID) for one of the plurality of dialog states, wherein the unique ID is based on information received when executing the voice application, wherein the information comprises attributes associated with one of the plurality of dialog states; storing the unique ID and other information associated with the dialog state; and graphically illustrating a call flow path of the voice application based on the unique ID and other information stored in the database.

Abstract: A system and method are disclosed for preventing intelligible interception of information signals transmitted over a two-direction line. A masking signal is applied through a hybrid circuit at the receiving end of the line, and this masking signal, which appears on the line together with the information signal, prevents intelligible decoding. Only at the receiving end of the line, where the hybrid circuit attenuates the masking signal which it receives at its receive port, can intelligible decoding take place. Signal processing techniques used at the receiving end permit larger amplitude masking signals to be used, thus creating even greater confusion for an unauthorized detecting mechanism which is coupled to the line.

Abstract: A technique for inhibiting intelligible interception of information signals transmitted over a line from a first site to a second site. A masking signal is applied to the line immediately upon the detection of the information signal at the second site, but prior to the time at which the validity of the signal is verified. As long as the information signal remains on the transmission line, the masking signal is repeatedly turned on and off to thereby inhibit decoding of the signal by an eavesdropping device.

Abstract: A system and method are disclosed for preventing intelligible interception of information signals transmitted over a two-direction line. A masking signal is applied through a hybrid circuit at the receiving end of the line, and this masking signal, which appears on the line together with the information signal, prevents intelligible decoding. The masking signal includes a series of frequencies which are sequentially applied. Only at the receiving end of the line, where the hybrid circuit attenuates the masking signal which it receives at its receive port, can intelligible decoding take place. The amplitude of the information signals is sensed at the receiving end and the amplitude of the masking signals on the line is adjusted to be great enough to provide security, by confusing an eavesdropping detector, yet small enough at the receiving end so that the receiving detector is not confused.
