-We’ve already touched on VoIP’s sensitivity to timings. One may state that, jitter above 25ms in either call direction, starts to impact and degrade call quality. The higher the jitter the more call quality will suffer. For a list showing only calls that were affected by bad jitter, filter (avgjitter > 25) is easily set within the search bar on the SIP calls screen.
