you need to configure nat=true (in asterisk web gui nat=1) for that extension.

I have configure in sip_addtional.conf as
[333]
username=333
type=friend
secret=333
record_out=Adhoc
record_in=Adhoc
qualify=no
port=5060
nat=true
mailbox=333@device
host=dynamic
dtmfmode=rfc2833
context=from-internal
canreinvite=no
callerid=device <333>

But the 333 account still cant connect to my asterisk behind nat. The client behind NAT too.
