Wireshark-users: Re: [Wireshark-users] Why does wireshark not recognize my RTP packets in the cor
Thanks a lot! I can not believe it was that easy! And shame on me for failing at that simple task.
Not only have you fixed my problem here, but now I already know, that my SIP implementation is incorrect.
Problem solved, no more mails needed, thanks! :)

If you right click on one of the packets and select decode
as, then select RTP, does it fix the problem? If so, go to edit preferences -
protocols - RTP and check all three boxes.
Hello,
at work I have programmed my own RTP stack to send data
(wrapped in RTP packets) through the network to another pc, where it can be
recieved by a voip application.
For testing purposes I am sending the RTP
data to my own computer and watching the traffic with wireshark, where I can see
all the RTP packets I sent. The problem is: Wireshark just recognizes those
packets as "UDP" and not as "RTP" as it should be. My first guess was, I did
something wrong in the RTP header. I checked it and everything there is OK, I
think.
And on top of that: If I select such and UDP packet, right-click and
decode it manually as a RTP packet, everything is fine. Now, with "decode as
RTP", Wireshark does recognize all my packets in the correct way. Every field of
the RTP header is correct. I compared it bit by bit with RTP packets from Ekiga,
it is exactly the same.
I now have spent several days, re-coding and
testing.
So my question is: How is that possible? Any Ideas? Why does
wireshark not recognize my RTP packets in the correct
way?
Greetings,
andre.
