Abstract
Grouping voice frames from multiple calls into a single packet as a means to reduce bandwidth requirement for IP voice calls is investigated. It is demonstrated that TCP-style Internet delay prediction can he instrumental to regulate the number of frames in each packet in a manner to minimize late losses of the frames under fast undulating Internet delay. The performance of the adaptive scheme is compared against those of fixed grouping cases with varying degrees of aggressiveness.
