International Classification:

H04M 3/42

US Classification:

37920301, 37940601

Abstract:

This is a method for use in a teleconference that troubleshoots echo problems. After receiving a code to begin the troubleshooting process, all legs of the teleconference are muted except a test leg. That test leg is evaluated for echo. The process is repeated for each of the legs of the teleconference. After automatically measuring echo on all legs, results are reported to a moderator or host, who can take action such as muting all legs with echo, or discussing remedial action with each participant on a leg with echo.

Abstract:

A method and system for administering a subjective listening test to remote users. A user can participate in a subjective listening test, such as an MOS listening test, over a telephone call. The telephone call is received and audio recordings are sequentially played over the telephone call. Quality ratings corresponding to the audio recordings are input by the user over the telephone call. The user can input digits corresponding to the quality ratings. This allows a user to take part in a subjective listening test without traveling to a lab.

International Classification:

H04M 1/60

Abstract:

A method and apparatus for providing privacy for telephone conversations over communication networks is disclosed. For example, a telephony endpoint device comprises a microphone for receiving an audio signal and a gain boost circuit, coupled to the microphone, for applying a gain boost to the audio signal. The telephony endpoint device also comprises a switch, coupled to the gain boost circuit, wherein operating the switch will control whether the gain boost is to be applied to the audio signal.
