There is a statistics area and you can select sip or voip calls to see calls. It shows packet loss, jitter, latency, out of sequence packets, etc. It can even play them back, so you can check where the loss is and play back the call to see if the noise is in the same spot. Here is some info from the wireshark website:

Do you know of a link that explains how to detect latency or jitter? My wireshark skills are pretty non-existent. Does it have a wizzy filter that will tell you or do you need to check the timestamps of the RTP packets? Any chance you could write up your technique? -- Thanks in advance, ------------------------------------------------------------------------- Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
