An administrator has determined that an end user is experiencing jitter. Which symptom is the end user experiencing?

Jitter refers to the inconsistent delay in packet delivery across a network. When voice packets arrive at uneven intervals, the receiving endpoint cannot reconstruct audio smoothly, resulting in choppy, broken-up audio quality for the listener.

Crosstalk is interference caused by signals bleeding from one circuit into another, not a symptom of jitter.

Static describes broadband noise or electromagnetic interference on a line, which is unrelated to packet timing variation.

Screeching is a high-pitched audio distortion typically caused by audio feedback or codec misconfiguration, not jitter.
