You also need to enable the ADD-IP extension in the library parameters,
something like this (extension to a code snippet from terminal.c) :

SCTP_getLibraryParameters(&params);
params.sendOotbAborts = sendOOTBAborts;
params.supportPRSCTP = 1;

params.supportADDIP = 1;
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
params.checksumAlgorithm = SCTP_CHECKSUM_ALGORITHM_CRC32C;
SCTP_setLibraryParameters(&params);


Let me know if that all helps,

best regards,
Andreas
