Using UCMA 5.0 and C#, if there is a conference call between two participants, participants A and B, I would like to modify Audio that participant B hears when A speaks, and vice versa.
From my knowledge there is only AudioVideoFlow that has the combined audio of two participants, it means I could not find a way to have a distinguished audio stream of the participants, modify them and replace it in the call.
I also know the SDP protocol is responsible for medias in the call, but can not figure out how to access it or change it based on my scenario.
