SIP trunk Settings Engin

Hi

I Am currently migrating from trixbox to freePBX. The only trouble I am having now is getting the SIP trunk to register.

The outgoing settings that work fine on trixbox are below. If I copy paste them into freePBX I keep getting a registration timeout from byo.engin.com.au.

PEER DETAILS

allow=ulaw&alaw
canreinvite=no
dtmfmode=rfc2833
fromuser=07xxxxxxxx
host=byo.engin.com.au
fromdomain=byo.engin.com.au
insecure=invite,port
secret=xxxxxxxx
type=peer
username=07xxxxxxxx

USER details

secret=xxxxxxx
type=user
context=from-trunk

Registration String
07xxxxxxxx:[email protected]/07xxxxxxxx

Maybe the lack of disallow=all before the allow statement.
