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
