here is the link to the example illustrating my problem !!!

http://www.iro.umontreal.ca/~sidhomiy/Test.zip




hello to everyone,
here is my problem.
there are 3 classes : NodeC,NodeA,NodeB.
and the jar files are libraries.
launch the example following this order :NodeC,NodeB,NodeA.

I said previously that NodeB doesn't receive the response from NodeC,
actually the stack Sip of NodeB receives the response, but the response
doesn't reach the upper layer (application layer) which is the
processResponse(..) of the SipListener interface.
Some way the response is discarded, I don't why yet !!!
it's been a week that I'm stuck with this bug.

thank you for giving me a hand in debuging this problem.
