Hi,
I hope this would be my last question about this SIP subject, I have managed to overcome the last issue I had by asking a friend to help me from a remote computer, I'm able to connect between the computers, but here is the thing, according to all the examples I saw, the Callee should invoke the Ringing
response, but in my application case I didn't implement it yet, but I still receive on the Caller UAC a Ringing
response, this is the SIP messages that are on the caller end:

I do not respond to the invite, that is why all this is happening, but why am I getting a ringing if I'm not the one sending it.
Thanks,
Adam.
