Voice packets are arriving at a destination with a variance of between 20 and 50 milliseconds. If the jitterbuffer has a capacity of 30 milliseconds, what is the impact on the audio at the receivers IP phone?Voicepackets are arriving at a destination with a variance of between 20 and 50 milliseconds. If the jitter bufferhas a capacity of 30 milliseconds, what is the impact on the audio at the receivers IP phone?
A. The jitter buffer will replay the previous voice packets to replace those packets that exceed 30 milliseconds to avoid speech gaps.
B. There will be no impact the audio stream because the audio packets are arriving in the jitter bufferwindow.
C. The DSP will automatically increase the jitter buffer size after sampling the range of incoming voicepackets to accommodate the wider range in variation of voice packet arrival times to avoid voice gaps.
D. The IP phone will negotiate in mid-call a lower bandwidth codec to reduce the delay in the arrival ofvoice packets to avoid voice gaps.
