Asterisk wont register with Outbound Proxy

My asterisk wont regsiter with my outbound proxy. It lets me know that it is “reachable” with 70ms latency but doesnt actaully regiser or show up in “sip show registry”.

Because it doesnt register, my sip provider rejects the call.

Here is the part of my sip.conf governing my outbound sip proxy:

[code]register=1234567:password@208.239.76.170:5060
registerattempts => 0

[varphonex]
type=peer
register=yes
register=1234567:password@208.239.76.170:5060
username=1234567
secret=password
realm=208.239.76.170
canreinvite=yes
insecure=port,invite
host=208.239.76.170
disallow=all
allow=ilbc
allow=ulaw
allow=alaw
qualify=yes
nat=no[/code]

Any ideas? How can i FORCE asterisk to register?

Try with nat=yes option.
