My Voip Application using pjsua returns 403 Frobidden on Call Transferring REFER request.

The Call transferring code is as follows,

public void transferTo(String destination) throws Exception {

        String transferString = "sip:" + destination + "@" + SipPreferenceManager.getDomain(context);

        CallOpParam param = new CallOpParam();

        currentCall.xfer(transferString, param);
        }

The response logs are as folows,

Use this code its works for me fine.

 if (currentCall != null) {
        CallOpParam prm = new CallOpParam();
        prm.setStatusCode(pjsip_status_code.PJSIP_SC_OK);
        try {
        currentCall.xfer("sip:" + transferNumber + "@" + serverAddress, prm);
        } 
         catch (Exception e) {
            System.out.println(e);
            }
       }

Thanks, Happy coding...
