Hi,
I am trying to simulate VoIP calls so I thought I could use PackETH to create an RTP stream and Wireshark to capture the traffic. I am building UDP packets with RTP payload on one end (win XP) and on the wireshark(other end windows 7) I can only see IP packets(info column= IP fragmented protocol). I am obviously doing something wrong……..
thank you for your help.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Open packETH, UDP is the default protocol
Click select payload, then enter the RTP values, choose frequency and length according to the codec you want to simulate
Capture this packet with Wireshark, it should be decoded up to UDP protocol.
The right click on this packet, Decode as… and select RTP.
At least on Linux this is the procedure, that works.

Hi i used packeTH to create an RTP stream for G7231 payload and wireshark to capture the traffic.I am building UDP packets with RTP payload on one end (windows 7) and on the wireshark(other end windows 7) but I can only see IP packets(info column= IP fragmented protocol).
Decode as option can be applied only if we can see as UDP packets, right? so what should be done if its showing only as IP packets?
Thanks in advance…

I think you will have to switch to Linux version. The problem with windows version is, that the fragment bit is always set I think and that is why you don't get the UDP options to select the payload…
I'm sorry but I won't be able to help you here much, because port to Windows was not done by me and I'm not able do build a new version (at least not now, I have the wish but don't have the knowledge). So I can only suggest you to try the Linux version, which has many other features as well.
Nice day, Miha
