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

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
And on top of that: If I select such and UDP packet, right-click and

wireshark not recognize my RTP packets in the correct
