First Claim
Patent Images
1. A method for detecting an attempt to mask a three-way call, said method comprising the steps of:
- monitoring an audio stream;
detecting when a power level of said audio stream exceeds a pre-determined threshold;
calculating an elapsed time when said power level of said audio stream exceeds said pre-determined threshold; and
determining whether said elapsed time exceeds a maximum allowable period of time,wherein the above steps are performed by a processor.

6. An apparatus for detecting an attempt to mask a three-way call, said apparatus comprising:
-
an interface for receiving audio streams from a telephone line; a microprocessor coupled to said interface for detecting when a power level of said audio stream exceeds a pre-determined threshold; wherein said microprocessor monitors said audio stream for a pre-determined time; and wherein said microprocessor determines whether said power level of said audio stream exceeded said pre-determined threshold for the duration of said predetermined time. - View Dependent Claims (7, 8, 9, 10, 11)
