This Integer32 object, measured in milliseconds, reports the interarrival jitter for a bearer connection as measured by the DSP and periodically polled by the host processor. Jitter reflects variability in packet arrival timing, and excessive jitter causes audible voice quality problems even when no packets are outright lost. A voice quality engineer troubleshooting choppy or robotic-sounding calls on a specific connection would check this value to see if jitter, rather than packet loss, is the root cause.
