I'm going to make an small call center application with ASP.NET. In this application the user will call the customer. However I've already learnt that there is no way to make an ASP.NET-based VOIP application.
Now, If it can be done with Silverlight, I want from you some reference, links or samples.
If it's not possible, I want some other advice. Maybe we can pass parameters from an ASP.NET application to another application (Java applet, Flash or Windows app).
