[Asterisk-Users] Asterisk NAT spa-2000

[Wiley E. Siler]

I would comment out these lines in sip.conf

;externip=111.222.333.444
;localnet=192.168.1.0
;localmask=255.255.255.0 


Then set nat=no

Hi All,

I have a asterisk box that is now on its own static address on the
net.it was originally behind a nat firewall.
The problem I have is that the remote SPA-2000's that are behind nat
firewalls now fail.

here is relevent sip.con entry
[2001]
type=friend
username=2001
host=dynamic
defaultip=81.178.77.67
allow=ulaw
dtmfmode=rfc2833
mailbox=2001 at local
context=sip
callerid="James" <2001>
secret=hidden
canreinvite=no
allow=ulaw
nat=yes
qualify=yes

I added the nat and qualify entries after hunting round google but still
get this error, spot the no nat bit.
 to 81.178.77.67:34504
