I don't think he has the option of binding to a specific address in this 
case;  here, the asterisk box is also the NAT itself, and there's only a 
single external IP address.   I seem to recall we were having even 
greater problems before your patch to fix binding to 0.0.0.0...  
However, it *might* work in this case to bind to the external address... 
we'll give that a try.  (Though I don't think we'll be able to do so 
until at least Wednesday, maybe later)

I may try digging through the asterisk code to see if I can figure out 
why it's sourcing packets with the wrong IP under these circumstances, 
but I doubt I'll be able to get to that for a little while.  What I find 
curious is that the Polycom phone seems to be rejecting the packets with 
the unexpected IP, but the softphone ("sjphone") seems to be OK with 
it.  I wonder if polycom has a setting for this...
