asterisk users - Sep 2007 - Problems with Asterisk behind a firewall

Hi all,
I have set up Asterisk and I am able to register with my SIP provider and
receive calls.
When I try to register with Asterisk from outside I can place calls but tthe
other person can't hear me.
Have opened port 5060 UDP as well as port 10000 to 20000 UDP. Any ideas?
Thanks,
Christian

I don't have enough experiment to help you, but I can suggest you this :
