unsigned int error_correction_entries

This option indicates the number of error correction entries transmitted in UDPTL packets and expected in received UDPTL packets.

◆ error_correction_scheme

enum ast_t38_ec_modes error_correction_scheme

This option indicates the error correction scheme used in transmitted UDPTL packets and expected in received UDPTL packets.

◆ error_correction_span

unsigned int error_correction_span

This option indicates the span of the error correction entries in transmitted UDPTL packets (FEC only).
