Man-in-the-Middle Operation

In Figure below, the gray boxes represent network hosts. The green boxes represent the SteganRTP application. The telephone icons represent the RTP endpoint applications, and the black arrows represent the two distinct RTP streams, one flowing in either direction. In this scenario, both instances of the SteganRTP application are running on intermediary hosts along the route between the two RTP endpoint hosts.
