◆ 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).

int far_max_datagram

The maximum size UDPTL packet that can be accepted by the remote device.

◆ far_max_ifp

int far_max_ifp

The maximum IFP that can be submitted for sending to the remote device. Calculated from far_max_datagram, error_correction_scheme and error_correction_entries, or -1 if it hasn't been calculated since the last changes were applied to the UDPTL structure.

◆ local_max_ifp

int local_max_ifp

The maximum IFP that the local endpoint is prepared to accept. Along with error_correction_scheme and error_correction_entries, used to calculate local_max_datagram.
