SCTP INIT has no response

i have problem in establishing SCTP connection i have give a small view of code.

• In case 1(SctpChannel.open(address,1,0)) I can see a INIT client side and ABORT from DRA. i dont know why i have abort message but atleast DRA(dynamic agent) is sending something there is also one more problem ipv 4 parameter is missing i thought that could be the problem. when i try to include a ipv4 parameter
• In second case(SctpChannel.open()) i see DRA is not sending any acknowledge only INIT from clent side no response from server. Can you help me i dont know what i have doing wrong here.

CASE 1:

InetSocketAddress address = new InetSocketAddress(peer.host(), peer.port());
channel = SctpChannel.open(address, 1, 0);
getSctpChannel(channel).bind(new InetSocketAddress(peer.srcIP, peer.srcPort));
getSctpChannel(channel).connect(address, 1, 0);
