    Config('123', '567');

             <telerik:RadWindow ID="ConfigRadWindow" runat="server" Width="750" Height="500" VisibleOnPageLoad="false" Behaviors="Move,Resize,Close" IconUrl="images/icoPhraseTranslationManager.png" Title="Configure" />

<script type="text/javascript">
 function Config(testID, UnitID) {
    var oWnd = radopen("Config.aspx?ID=" + testID + "&UnitID=" + UnitID, "ConfigRadWindow");

I am able to call aspx page with use function but requirement is that to call this Config()function through js function.

   at config (VM84 config.js:7)'

Config() is not defined in the references JS. surely something is missing as a connect.

Check with developer tools to see if the JS and function is there for the page to use.

If you're trying to call a Javascript function in a parent page from a page loaded inside an iframe, you need to prefix the function name with parent. to indicate that it's defined in the parent document.
function Test(){
    parent.Config('123', '567');
