Forward error correction (FEC), when the two parties establish a call and detect that the media stream packet loss exceeds 0.1% within 10s, the super error correction function will be enabled, and the super borrow correction function will divide a part of the call bandwidth. It is used to transmit redundant code streams that are resistant to packet loss.
