Abstract
A system which compensates for jitter in the transfer of voice data over packet data networks. A predetermined quality of service factor is used to determine the jitter delay for received voice packets in order to optimize the number of voice packets received. The invention uses packet sequence information in the voice packet protocol to determine which voice packets are missing and which voice packets are late within a predetermined statistically significant interval. The jitter delay is decreased when the number of missing packets is significantly less than that specified by the quality of service factor. In most cases, the jitter delay is increased when the number of missing packets is greater than that specified by the quality of service factor. The jitter delay is not increased past a certain value when no late packets are observed during the predetermined interval.
