  • Efficient voice activity detector to detect fixed power signals
    Patent number: 8311814
    Abstract: The present invention is directed to a voice activity detector that uses the periodicity of amplitude peaks and valleys to identify signals of substantially fixed power or having periodicity.
    Type: Grant

    Date of Patent: November 13, 2012
    Assignee: Avaya Inc.
    Inventors: Mei-Sing Ong, Luke A. Tucker
  • Clock management between two end points
    Patent number: 7936794
    Abstract: Clock correlation can be achieved, for example, utilizing the RTP stream between a sender and receiver by determining a baseline at the start of, for example, a communication. This baseline is derived as a point in time from an arriving packet and represents a point from which subsequent packets deviate. Using this baseline, an early packet or a late packet can be detected. An early packet pushes the baseline down to that earlier point, while late arriving packets, if they are arriving late for a continuous period of time, represents a shift in the opposite direction from the baseline, resulting in a baseline moving to the “earliest” packet out of the sequence of the late arriving packets.

  • Answer on hold notification
    Patent number: 7881450
    Abstract: An answer on hold notification feature is provided. The answer on hold notification feature is activated when a call is waiting for servicing by a human agent. For example the feature may be activated when the call is placed on hold by the user of the first communication endpoint. By providing an answer on hold notification signal feature, a user can engage in a second call, or perform other tasks, without the risk of losing an opportunity to speak with a human agent as a result of attending to such other call or task.
