voipuser.org

I am currently using voipuser.org for sip trunking. I am able to place calls fine from a sipura ATA but when trying to add configs to my trixbox I can never get the trunk to register. I am using Trixbox Ce over NAT DSL connection

My trunks settngs are below.. what am I doing wrong?

----Peer
canreinvite=no
context=from-pstn
fromdomain=sip.voipuser.org
fromuser=myuser
host=sip.voipuser.org
insecure=very
qualify=no
secret=mypass
type=peer
username=myuser

----user details
context=from-pstn
fromdomain=sip.voipuser.org
fromuser=myuser
host=sip.voipuser.org
insecure=very
qualify=no
secret=mypass
type=friend
username=myuser

---Register string
myuser:mypass@sip.voipuser.org/448449330408

thanks for the help
