For what it's worth, I downloaded the latest unstable source snapshot.
After building the pcap-enabled binary, I ran my same scenario. It
looked like SIPp sent the audio RTP to the correct port for a brief
moment, but then SIPp segfaulted before I saw any video RTP.
I don't really feel like debugging segmentation faults, so I applied
Jordan's patch to the stable version and rebuilt. Now my audio and
video are being sent to the correct ports and the test is working.
For what it's worth, Jordan's change appears to NOT be in the latest
unstable source code. So maybe somebody fixed part of the problem some
other way. But it's hard to say if it's completely fixed since SIPp
crashes before completing even the first call.
Thanks Jordan!
Cheers,
Todd.

Subject: Re: [Sipp-users] SIPp Linux is sending pcap media to
wrong port
On Windows, I'm using this:
SIPp v3.1-PCAP, version svn456, built May 30 2008, 09:41:13.
On Linux, I'm using this:
SIPp v3.1-PCAP, version unknown, built Jul 31 2009, 17:29:33.
In both cases, it's the latest SIPp "stable" version available
on http://sipp.sourceforge.net. Is it a bad idea to use that version?

Hello,
Which sipp version you are using for windows for which
it works ?
Are you trying with the latest linux src present in the
snapshots ?

Anuj

This is definitely a known bug. There's a patch
for it, I know I submitted one a while back, but I doubt it got included
into a build. Someone else wrote this up too.
See the following:

Let me know if you need some more guidance.

I'm running SIPp on both Windows (using
pre-built binaries) and Linux
(64 bit CentOS system, built from
source). I have a scenario where I'm
sending audio and video media from my
SIPp scenario to a video
conferencing system.
The scenario works fine under Windows,
but I was wondering why the audio
and video aren't played when I run the
scenario under Linux. Using
Wireshark, I found that SIPp is not
sending the audio and video RTP
packets to the port numbers specified in
the SDP. Instead, it appears
to be truncating those numbers.
In the 200 OK message from the UAC, the
SDP says to use port 49160 for
audio media and port 49170 for video
media. However, the actual RTP
packets are being sent to ports 4916 and
4917, according to Wireshark.
Has anyone seen this, and do you have a
workaround or patch for it?
Thanks,
Todd.
