I can't imagine any normal network where you would get duplicate RTP packets (they are UDP datagrams, so who is going to resend them?) Regards, Martin MartinVisser99 () gmail com On 11 April 2011 17:30, RUOFF, LARS (LARS)** CTR ** < lars.ruoff () alcatel-lucent com> wrote:
What you describe can happen if you have all packets as duplicates or if they all have the same RTP sequence number. Your sample capture file will tell us. If you limit the file to a reasonable size (10 successive RTP packets from the stream will be sufficient to see where the problem is), there's no problem for posting it as an attachment on this list.

The jitter results match what I expect, but the packet loss results do not. I know for a fact that the file contains no packet loss and yet the RTP analysis screen reports all packets as lost "negatively" (and gives an odd -100% value). Any ideas?
