Have you tried using a SOAP Client Class to send a message directly to a web service?  Check the code below.  I hope this helps.


SOAP Client Class and a ReturnResponse function:

<SoapServiceAttribute("urn:Sample")> _
Public Class SOAPServiceClient
    Inherits SoapClient

    Public Sub New(ByVal [to] As Uri)
    End Sub 'New

    Public Delegate Function SendFunctionHandler(ByVal messsage As SoapEnvelope) As SoapEnvelope

    Private ResponseHandler As SendFunctionHandler = AddressOf SendFunction

    ' This method represents a web service operation for sending a SOAP message
    <SoapMethod("")> _
    Public Function SendYourMessage(ByVal message As SoapEnvelope) As SoapEnvelope
        'Return CType(MyBase.SendRequestResponse("SampleAsyncResponseService", message).GetBodyObject(GetType(String), SoapServiceAttribute.TargetNamespace), String)
        Dim AsyncResult1 As System.IAsyncResult
        AsyncResult1 = ResponseHandler.BeginInvoke(message, Nothing, Nothing)

        While Not AsyncResult1.IsCompleted
        End While

        Return ResponseHandler.EndInvoke(AsyncResult1)

    End Function

    <SoapMethod("")> _
    Public Function SendFunction(ByVal message As SoapEnvelope) As SoapEnvelope
        'Return CType(MyBase.SendRequestResponse("SampleAsyncResponseService", message).GetBodyObject(GetType(String), SoapServiceAttribute.TargetNamespace), String)
        Return CType(MyBase.SendRequestResponse("SampleAsyncResponseService", message), SoapEnvelope)
    End Function
End Class

SOAP Client Class Instantiation:

Private Function ReturnYourResponse(ByVal SEnv As Sample.Envelope) As String
            Dim proxy As New SOAPServiceClient(New Uri("http://whateveristhisnotASMX/webservice"))
            Dim Env As New SoapEnvelope

            Dim myContext As SoapContext = Env.Context
            Dim token As New UsernameToken("username", "password", PasswordOption.SendPlainText)
            myContext.Security.Actor = ""
            myContext.Security.MustUnderstand = False
            Env.Context = myContext

            Dim ReturnedSoapEnv As SoapEnvelope = proxy.SendFunction(Env)

            Return ConvertXmlToString(ReturnedSoapEnv.Body)  
        Catch ex As Exception
            Return ex.Message
        End Try
    End Function
