Hi, The "X" on the stream appears if at least one packet is marked non-OK. non-OK currently includes: * Comfort noise (PT=13 or PT=19) * Wrong sequence nr. * Changes in Payload type (PT) * Incorrect timestamp * Marker missing? for details, see gtk/rtp_analysis.c As you can see, there's no check concerning the latency or framing. For other info around RTP analysis, see http://wiki.wireshark.org/RTP_statistics Regards, Lars -----Original Message----- From: wireshark-users-bounces () wireshark org [mailto:wireshark-users-bounces () wireshark org] On Behalf Of Patrice Bertin Sent: jeudi 6 octobre 2011 15:19 To: wireshark-users () wireshark org Subject: [Wireshark-users] Latency in RTP streams Hi everybody, I have a capture example of a SIP call with G711 codec. Looking at the RTP streams, the final field shows an X which normally means that we have a VoIP related problem. By selecting the problematic stream and analysing it, wireshark provides a packet-by-packet look at the stream. The thing I don't understand, is why does it give me the status "OK" everywhere if I have the famous X and especially when I have a latency of 5843.74 ms (cf the screencapture joined in the mail). Other thing, which values Wireshark put for the latency and jitter? Is it possible to modify it? I hope this is understandable enough. Thanks for your reply Patrice ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
