Hello.

Anybody from developers could please clarify if FreeSWITCH uses Forward
Error Correction feature in opus codec? We actually are not a specialists
in C and cannot fully understand how decode function works in 414 line.
According to opus documentation decode function  is called with special
flag if previous packet is lost in order to call fec feature. In mod_opus
it is hard to say for me as i don't see i or i+1 packets. Thanks
