delay the sending of FEC packets for a predetermined period after the primary audio
stream's packets are sent. This will increase the likelihood that the FEC packets will

that FEC packets taking an alternate route will be received and replace them. When
a FEC percentage lower than 100% is configured, FEC packets are automatically
delayed based on the ratio of primary packets to FEC packets sent at the selected
setting.
