what is the impact on the audio at the receivers IP phone?

Voice packets are arriving at a destination with a variance of between 20 and 50 milliseconds. If
the jitter buffer has a capacity of 30 milliseconds, what is the impact on the audio at the receivers
IP phone?Voice packets are arriving at a destination with a variance of between 20 and 50
milliseconds. If the jitter buffer has 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
buffer window.

C.
The DSP will automatically increase the jitter buffer size after sampling the range of incoming
voice packets 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 of voice packets to avoid voice gaps.
