When i'm trying to get the response from soap service i'm getting the following error.

The header 'ReliableMessaging' from the namespace 'http://sap.com/xi/XI/Message/30' was not understood by the recipient of this message, causing the message to not be processed. This error typically indicates that the sender of this message has enabled a communication protocol that the receiver cannot process. Please ensure that the configuration of the client's binding is consistent with the service's binding.

What I have tried:

I'm using this in script task in SSis package. below is the code i'm using to pull data.

EndpointAddress endpointAddress = new EndpointAddress(Properties.Settings.Default.SegmentServiceAddress);

           SegmentsClient client = new SegmentsClient(BindingUtility.GetInitiativesBinding(), endpointAddress);
           client.ClientCredentials.UserName.UserName = "sys_cons";
           client.ClientCredentials.UserName.Password = "xxxxx";

           SegmentResponse results = client.ListSegments(new SegmentRequest() { SegmentName = "" });

I don't have much knowledge in Asp.net or Soap Web service. Correct me if i'm doing anything wrong or if i'm missing something here. Thanks in advance.
