Cool.  But note again that I don't actually want the functionality  
myself, i.e. this is certainly not my lobbying for it.

I think what triggered it was the combination of the problem with hand- 
configured port forwarding from a couple weeks ago combined with a  
recent, albeit misdescribed, question about port forwarding.  Somehow  
this made me wonder whether the SoHo focus of so many Asterisk users  
resulted in uPnP/NAT-PMP support being added.  It was much easier to  
ask here than to go find it in an Asterisk feature list... ;)
