Asterisk 1.4 calling voip providers

Asterisk Asterisk Support

I have installed 1.4.2 and when I attempt to call using a voip provider sip, I can not hear the other person or answering machine. An IAX2 provider appears to work

What have I done wrong in my configuration.

Here are the messages from the console

-- Executing [710015732041111@numberplan-custom-1:1] Dial("SIP/2001-082e57d8", "SIP/trunk_1/0015732041111") in new stack

How do I setup a stun server, since the asterisk box is behind a firewall.

Thanks

Stun should not be required if your asterisk box is using a static IP. Make sure to use externip in your sip.conf and forward the following ports to your asterisk box.

UDP 5060 - 5061
UDP 10000 - 20000
