Hi when I run this routine:

 private void VoicepayCCProcess(string sRecordline, string sRequeststring)
        {
            try
            {
                string result;

                HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://secure.voice-pay.com/gateway/remote_auth");
                request.ContentType = "application/x-www-form-urlencoded";
                request.Method = "POST";

                using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
                {
                    writer.Write(sRequeststring);
                }
               
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                using (StreamReader reader = new StreamReader(response.GetResponseStream()))
                {
                    result = reader.ReadToEnd();
                }

                // Once we get response back from the voicepay we can construct the output file line by line.
                WriteToFile(sRecordline, result);
            }
            catch (WebException ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

On this line:  using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))

I'm getting this error:
the remote server returned an error 407 proxy authentication required

Can you  help me please.

If you are behind an ISA server then you need to allow https traffic through if it is already allowed then you need to monitor and see what other traffic is being sent and received.

This was such a weird error to handle when I came across it a few weeks ago...

Add this into your app.config file:
system.net>
  <defaultProxy
    useDefaultCredentials="true" >
  </defaultProxy>
</system.net>

And all should work fine...
