very basic softphone using C#

We need a starter program to get us started with a much larger project. We are looking for a windows forms application, written in C# that will contact an [asterisk][1] server and call an extension. The extension must be modifiable by selecting a textbox. The application must use the [RTC API][2]. [This][3] will help you get started with the RTC API in C#. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in C# and contain an SLN file that is compatible with Visual C# 2002. It must be able to communicate to proxy through an asterisk server and connect to an extension. We are using x-lite to verify the extension connection succeeds. The code needs to be neat and well documented. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). 4) The code MUST use the Microsoft RTC SDK. 5) You need not include an installer. ## Platform client software, Windows XP Must be able to communicate with asterisk (linux)
