Adaptive Coding and Packet Rates for TCP-Friendly VoIP Flows
... TCP friendly manner in order to optimize the quality of VoIP flows. The conversational call quality of VoIP flows depends on the transmission delay and on the speech quality [2]. For example, a higher coding rate usually gives a better speech quality. On the other hand, if the packet rate is set low ...
