[Freeswitch-users] RTCP and OPUS

[Kamil Nigmatullin]

I don't know how it organaized in freeswitch. But opus C library is a
library and all features should be called. So, if bandwitdth changes, you
must call this feachures manualy, by feeding parametures each time it
accures. So to be sure, that the other end is changing rate or looses
packets, we somehow need to communicate with it and RTCP is a standard that
actually stands for this.
