How to build a C# Command Line Caller?

[CesarG]

I have just downloaded this C# Command Line Caller sample program of Ozeki VoIP SIP SDK: links are not allowed so please google voip sip sdk command line caller...
It is very easy to use and meets my requirements, but I would really appreciate some extra info from more experienced developers. Has anyone ever built a C# Command Line Caller?
