This read-write integer, from 10 to 255 milliseconds, sets the amount of jitter buffering the unit's voice function applies to smooth out variable packet arrival times. An administrator increases this value when the underlying network shows inconsistent latency, trading a bit of added delay for fewer audio glitches. For example, on a WAN link with noticeable jitter, raising this buffer from a low default would reduce choppy or garbled voice audio at the cost of slightly higher call latency.
