    Hello all,
    I'm developing an application for CISCO IP Phone 7079 and I want to push sound to the IP Phone so I've wrote this method in C#
    public void Phone_push(string PhoneIP, string ServiceUrl, string UserName, string PassWord, string mytext, string myfrom)
     string URLIPPHONE = "http://" + PhoneIP + "/CGI/Execute";
     // Create a request using a URL that can receive a post.
     WebRequest request = WebRequest.Create(URLIPPHONE);
     // Set the Method property of the request to POST.
     request.PreAuthenticate = true;
     request.Credentials = new NetworkCredential(UserName, PassWord);
     request.Method = "POST";
     string text = HttpUtility.UrlEncode(mytext);
     string from = HttpUtility.UrlEncode(myfrom);
     string amp = HttpUtility.UrlEncode("&");
     string postData = "XML=<CiscoIPPhoneExecute><ExecuteItem URL=\"" + ServiceUrl + "?Text=" + text + amp + "From=" + from + "\"/></CiscoIPPhoneExecute>";
     //string postData = "XML=<CiscoIPPhoneExecute><ExecuteItem Priority=\"0\" URL=\"Play:chime.raw\"/></CiscoIPPhoneExecute>";
     byte[] byteArray = Encoding.UTF8.GetBytes(postData);
     // Set the ContentType property of the WebRequest.
     request.ContentType = "application/x-www-form-urlencoded";
     // Set the ContentLength property of the WebRequest.
     request.ContentLength = byteArray.Length;
     // Get the request stream.
     Stream dataStream = request.GetRequestStream();
     // Write the data to the request stream.
     dataStream.Write(byteArray, 0, byteArray.Length);
     // Close the Stream object.
     // Get the response.
     WebResponse response = request.GetResponse();
     string s = response.ToString();
     // Get the stream containing content returned by the server.
     dataStream = response.GetResponseStream();
    Where I'm sure from parameters passed and IP Phone is open and working correctly
    I alwayes get the error "Error (504): Gateway Timeout", so why this error arise?
    Thanks in advance

    With this we can't understand where the error comes from.... It would be helpful if you could do a IP packet capture at the phone side and see the interactions on the phone, the XML it received, what it's trying to do next kind of.
    Most probably it's a C# implementation problem. Ethreal / wireshark trace will clear that out.
