[Freeswitch-users] Opus PLC issue - can this be a bug?

[Dragos Oancea]

Hi

I have tested yesterday FS master 
(b5e486fd5c9bfb52923b30b8b53037c39cdb8665) with Opus PLC and I can tell 
you that it works just fine .
If there is/was a bug it must have been because of rtp & rtcp mux/demux 
,  by looking at the
error message about payload type. Do those errors show at regular 
intervals ? eg: 5 seconds , which can be the rtcp interval ?

Regards,
Dragos
