Hello, I've already debugged it, and it is a question of frame classification. AFAIR the code responsible for the classification is in MprEncoder (I'm on holidays so I can't check it right now). The frames classified as silence aren't pushed down the graph and are not sent onto the wire. It's enough to comment out one line of code to disable it. I think it's better to not use the frame classification until CN "codec" is implemented.
