You're right! I was aware of duplication of SIP packets, but I have it disregarded because I thought this was some normal behavior of the SIP proxy to compensate for possible loss of packets. But now seeing that even ICMP is showing up duplicated it is clear something is wrong with the machine. I checked packets on the distant end and nothing is duplicated there. So this is some issue in the machine running tcpdump which is the same that is running SIP and RTP proxies. Thank you for your time and sorry for the wrong report. regards, takeshi _______________________________________________ Users mailing list Users@rtpproxy.org http://lists.rtpproxy.org/mailman/listinfo/users
