The Internet telephony gateway receives the transmitted voice packets(S510). The Internet telephony gateway checks a sequence of the received voice packets(S521-523). The internet telephony gateway generates threads for the received voice packets(S531-533). The threads for the received voice packets determine whether a buffering command for the received voice packet is received from each thread manger within a determined time(S541-543). If not, the threads become time-out states(S551-553). If the buffering command is received within a determined time, the threads respectively buffer the received voice packets to a buffer(S561-563). If the threads become the time-out states and the received voice packets are buffered, the threads are removed(S571-573). The Internet telephony gateway lights the buffered voice packets to a digital signal processing(DSP) according to the checked sequence(S580).
