PVX 8.0.2) and checked the packet traffic using<br>> wireshark.<br>><br>><br>><br>> I use RTP stream analysis of wireshark for viewing the result, and I notice<br>> that every packet(which is final slice of a frame, contain Marker=1) has a<br>> status of "Incorrect timestamp".<br>><br>><br>><br>> 1. Why it behave like this?<br>><br>><br>><br>> 2. Does it affect the receiving site during a conference meeting?<br>><br>><br>><br>> 3. Is there any timeout for RTP packet handling(like dropping packet) in<br>> h323plus? Because I found out that it cause large packet loss during the<br>> conference compare to other h.323<br>><br>> system on the same situation(ie. same executing environment).<br>><br>><br>><br>> Btw, I have done some enhancement on MyOutput display according to the<br>> suggestion of "Simon" to one of the h323 member, to avoid dropping packet.<br>><br>><br>><br>> Thanks.<br>><br><br><o:p></o:p></p></div></div><p class=MsoNormal><span style='color:#888888'>--<br>Jan Willamowius, <a href="mailto:jan@willamowius.de">jan@willamowius.de</a>, <a href="http://www.gnugk.org/" target="_blank">http://www.gnugk.org/</a></span><o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p></div></body></html>
