Outbound is working for me. Here are my settings:

host=codeblue.voipo.com
username=9192491xxx
secret=(not telling, then it wouldn't be a secret anymore. )
type=peer
insecure=very
qualify=yes
nat=yes
port=5080
I don't know if the port or the "insecure" setting makes the difference, but that's how my settings are different than yours... I don't see how the nat setting would matter (I'm behind a home router, hence the 'yes').
