Hi everyone,

I am doing a simple test, I interconnected 2 Windows XP clients through a 
crossover cable, recompiled SIPp with PCAP support using Cygwin, and run the 
following commands:
    On client 1:    sipp -sf g711a_pcap.xml users 2 192.168.0.2
    On client 2:    sipp -sn uas

Everything works fine when I use 2 Windows XP clients, RTP packets are 
transmitted and can calculate jitter, delay...

-> However I have a problem when I run the above commands on 2 Mandriva Spring 
2008 clients (using the same .xml and .pcap files as with the WinXP clients) 
still interconnected through a crossover cable and compiled using "make 
pcapplay". Basically I cannot see any RTP packets going through (so cannot 
calculate jitter...), has anyone had this issue before? I do not understand why 
I do not see any issue with the Windows base clients...

Did a final test, a WinXP client connected to a Mandriva client, here again no 
RTP traffic. As soon as I involve a Linux client I do not get the RTP traffic.

Note: I use the latest SIPp build for both Windows and Linux.

Thanks if anyone can help,
Antoine
