30. A method for creating a ternary bitmap of an audio segment from an outbound call, the method comprising the steps of: a) computing a binary acoustic fingerprint bitmap of the audio segment; b) deleting a first number of samples from the audio segment; c) after step (b), computing another binary acoustic fingerprint bitmap of the audio segment; d) repeating steps (b) and (c) a plurality of times to create a plurality of binary acoustic fingerprint bitmaps; and e) combining the plurality of binary acoustic fingerprint bitmaps into the ternary bitmap, where each bit in the ternary bitmap is determined as follows: e.1) If a bit is 0 in a first predetermined number of the plurality of binary bitmaps, set the bit in the ternary bitmap to 0; e.2) If a bit is 1 in a second predetermined number of the plurality of binary bitmaps, set the bit in the ternary bitmap to 1; and e.3) Otherwise, set the bit of the ternary bitmap to *, wherein * is a Don't Care.

The method of claim 30 , wherein said first predetermined number comprises all of the plurality of binary bitmaps and said second predetermined number comprises all of the plurality of binary bitmaps.
