This is the relevant part of sip.conf

I orignally tried without the last two lines, then
added these and forwarded all ports from
the NAT to the asterisk server, but still no result.
Is anyone with asterisk behind a NAT successfully receiving calls
from FWD? Can you give me any pointers on the above configuration?
I realize that I could also try IAX which is supported by FWD, but
I'm having this problem with another SIP provider too, so I'd like
to get it working for SIP.
Hi,
Those 2 lines about externip and localnet should go before
any register or phone/provider stanza.
Check if you are registered to fwd/other sip provider.
In asterisk CLI type: sip show registry.
If you forwarded all ports that are stated in rtp.conf and
the 5060 to the asterisk box it should work. At least it
does here.
thanks for the help. I moved the externip and localnet definitions
to the [general] section and now I can receive calls from FWD and
other sip providers.
Just for the list archives in case someone is looking to solve a
similar problem, here is some additional information which I
found useful: initially after applying the above solution I still
found that asterisk was not picking up the calls from FWD.
So I did a tcpdump -e -A to see the contents of the packets
being exchanged with the FWD sip server. I saw that asterisk
was sending an INVITE to the FWD sip server upon receiving
the initial incoming call request.
By adding insecure=invite to the [fwd.pulver.com] section
of sip.conf, this stopped asterisk issuing INVITE and asterisk
responded directly to the incoming calls.
