Hi All,

I want to duplicate SIP headers using Jain SIP Stack.
Am not able to do so while creating a response using the
below mentioned code.

CSeqHeader c = (CSeqHeader) res.getHeader(CSeqHeader.NAME);
            res.addHeader(c);
            res.addHeader(c);
            res.addHeader(c);
            res.addHeader(c);
            res.addHeader(c);

My expected output is as follows:

SIP/2.0 401 Unauthorized
Call-ID: [email protected]
Cseq: 4 REGISTER
Cseq: 4 REGISTER
Cseq: 4 REGISTER
Cseq: 4 REGISTER
Cseq: 4 REGISTER
From: <sip:[email protected]>;tag=3c001267
To: <sip:[email protected]>;tag=39a87697

Contact: "UserA" <sip:[email protected]:5070;transport=udp>

Pls tell me where I go wrong.

Thanks in Advance..!!
