[Freeswitch-users] RTCP and OPUS

Hello all. What I basicly want is to have real adaptive codec on both sides (client and FS), that could exchange link quality information through RTCP. As far as I see, after a brief looking through some parts of source code of FS, mod_opus works as static codec and don't change its behavior when Internet link is changing because it has no communication with RTCP module. Could anybody of developers recommend me the most efficient way to deploy this communication process through Freeswitch Core? Is there a way to export and import information from/to module/core during the call? Thanks in advance.
