command line calling

Hello everyone,

I am a PhD student in Stockholm, studying VoIP technology. I am in the middle of writing my dissertation, about command line calling.
As I'm doing my researches, I've already found some very interesting research material, such as this page:
XxXwww.voip-sip-sdk.com/p_251-how-to-use-the-command-line-caller-example-with-ozeki-voip-sip-sdk-voipXxX (cancel the X-s)
It would be great to find someone to discuss this program, or maybe a whole group, because it would really help me with moving on.
Any advice is welcome!
Thx
