asterisk users - Oct 2007 - A linksys SPA921 behind NAT and firewall

I've got someone sat in a home-office with an SPA921 behind NAT, and
most probably a firewall.  I've got a STUN-server running, and calling
in from the SPA921 to our Asterisk box works fine - though I had to
open the firewall for UDP traffic on port 10000-20000. 

Calling from our Asterisk to the SPA921 doesn't work.  I'm guessing this
is due to the NAT/firewall on the other side, coz' how would it know
that UDP-traffic to <SPA publicIP>:5060 needs to be delivered to
<192.168.x.x:5060> ?

Did you set "NAT Keep Alive Enable: = Yes" for the line in question in
the SPA's configuration?
