SCTPDrv looking for help

Hello, I have used SCTPDrv of Brucec. I need to send BICC traffic through SCTP and stream id, payload type and sequence-id of sctp is impotent for me. I see that the driver can send stream-id up to 9 without any problem; but as soon as the stream-id exceeds 9 the sctp_send function returns error. The WSAGetLastError returns the error code 10022 (WSAEINVAL : some invalid item has been found). I want to know if any factor can restrict the stream-id. Is bandwidth of network interface or any other factor causes the limitation? Please help me resolve this problem.

I put a peace of the code that I have used for transferring SCTP data-payload bellow.

Regards
