I know this is resolved but I just thought I would though it out
there, the source code for the dissectors wireshark uses are available, if
there is every a question on why or how something is happening the answers in
the source. (although I think the below is a must faster options)

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.

Subject: [Wireshark-users] Why does wireshark not recognize my RTP
packets in the correct way?
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.
