Hello list,
I'm trying to get a simple "hello world" sample up and going and I am
having trouble sending and receiving an INVITE. I've looked at
http://wiki.opensource.nokia.com/projects/SofiaTutorial and I can send and
receive a simple message. But I would like help sending and receiving an
INVITE (the API is still very new to me).
Below is my humble attempt, can anyone see where I have messed up big time
and help me resolve the issue.
I would like the Caller to send the invite to the Callee.
Thank you in advance!
