| AbstractThe present invention applies the waveform interpolation method to restoring and generating the dropout current IP voice packet when the current IP voice packet is dropped out or unreached by relaying at the receiving end under the condition that the last and the next IP voice packets are existed. The linear predictive method is applied to restoring and generating the dropout current IP voice packet if the last iP voice packet is existed only and the restored current IP voice packet is decoded for outputting to improve calling effect of IP telephone service. | |||
