I have found a gateway (Ozeki NG SMS Gateway) that can be used to send out SMS messages from an ASP application. In order to send a message, the application has to perform an HTTP request. The built-in webserver of Ozeki NG - SMS Gateway receives the request and adds the posted SMS message to the outgoing message queue.
To send an SMS message from ASP, you can use the code below. This example code will send a text message containing the text "Hello World" to the +36205222245 telephone number.
http://localhost/smssend.asp <% Dim strMsg Dim strReceiver Dim strUrl ' Retrieve the posted items from the HTTP-SMS gateway strUrl = "http://localhost:9501/ozeki?" strRequest = "username=admin"; strRequest = strRequest+"&password=abc123"; strRequest = strRequest+"&action=sendMessage"; strRequest = strRequest+"&messageType=SMS:TEXT"; strRequest = strRequest+"&recipient="+Server.URLEncode("+362052
22245"); strRequest = strRequest+"&messageData="+Server.URLEncode("Hello World"); strUrl = strUrl+strRequest; 'Create InternetExplorer Dim WebBrowser: Set WebBrowser = CreateObject("InternetExplorer.Application") WebBrowser.Navigate strUrl Do While WebBrowser.busy Loop WebBrowser.Quit 'Display message info to the user Response.Write("The message has been sent . " + chr(13)) %>
Also on related pages I could get useful idea regarding ASP with built in webserver C#. http://www.ozekisms.com/index.php?owpn=205
Maybe this SMS API can help you too to develop SMS applications in ASP.NET.
