  • System and method for minimizing overrun and underrun errors in packetized voice transmission
    Publication number: 20030191631
    Abstract: When it is determined that a sample queue exceeds a first predefined level, samples being received from a IP switched network are modified such that samples are removed within the voiced region of the samples by removing whole pitch periods of samples. If the sample queue is below a second predefined number, additional samples are placed into the queue by analyzing voiced samples from the IP switched network and generating additional pitch periods of samples.
