asterisk users - Apr 2005 - Can't get incoming calls with IAX trunks (FWD & Teliax)

I have Asterisk@Home 0.9 running, and everything seems
to work well EXCEPT incoming calls.

I have an FWD and Teliax trunk (both using IAX), and a
Cisco 7960 SIP phone connected to Asterisk. 
Everything tests fine:

-	Can call from softphone to Cisco and vice versa
-	Asterisk inbound simulation works like a champ
-	Voicemail works fine
-	Outbound calls to both trunks works fine

However, when I call into my system on the FWD or
Teliax trunks, nothing happens.  Nothing appears on
the asterisk console so I’m not even sure where to
start.  I’m suspecting network problems, but don’t
know what to look for.  My asterisk box sits on my
LAN, behind an IPCop-based NAT router.  I’ve forwarded
port 4569 UDP and TCP to the asterisk box, but still
no joy.  I’ve googled and checked voip-info, but
everything that mentions NAT as a potential problem
points to IAX as the solution.  Trunk-wise, I’m pure
IAX (only SIP is the 7960, and it’s on the same
network as the asterisk box).

I’m pretty new to asterisk, so if you can dumb down
any debugging advice I’d appreciate it.

Thanks a ton!

Maybe you can post the parts of your config that pertains to your question?

This question will be better addressed on the aah forums.

I would suggest:
1) have you setup a  DID?
2) take a look in the log file 
tail -f /var/log/asterisk/full
3) see the numerous threads on the aah forums about how to configure FWD
and Teliax (and other providers)

I personally have both FWD and Teliax working perfectly fine with aah.

Here are the relevant parts of my iax_additional.conf. Of course you should
replace USERID, FWDNUMBER and PASSWORD with yours. Of course you should not
change iax_additional.conf directly, but paste the different parts in AMP

-------------- excerpt from iax_additional.conf --------------
register=USERID:PASSWORD@voip.teliax.com
register=FWDNUMBER:PASSWORD@iax2.fwdnet.net

[fwd]
username=FWDNUMBER
type=peer
secret=PASSWORD
qualify=yes
host=iax2.fwdnet.net
disallow=all
context=from-pstn
auth=md5
allow=ulaw

[fwd-in]
type=user
inkeys=freeworlddialup
disallow=all
context=from-pstn
auth=rsa
allow=ulaw

[teliax]
username=USERID
type=friend  ; one should think it has to be peer, but that does not work
secret=PASSWORD
host=voip.teliax.com
context=from-pstn
auth=md5

[teliax-in]
username=USERID
type=user
secret=PASSWORD
host=voip.teliax.com
context=from-pstn
auth=md5
