I wish to develop an own application. There was a site (Ozeki C# VoIP SDK - A SIP SDK for software developers) that offered lots of sample programs. These samples were built upon an SDK called Ozeki VoIP SIP SDK and they are in C#. My problem is that I have a little experience in C and C++ and none in C#. Could you please provide me with a solution how to start using this software? Do you think I should get back to it after I gained experience in C#? Thanks and awaiting your suggestions.
