I started with this, but since it's a partial solution I didn't feel 
that it really made sense to continue down that road. Also, it doesn't 
work for when two SIP peers are on different RFC1918 networks and cannot 
talk to each other (since Asterisk would think it was safe to reinvite).

I will try to put together something for CVS to allow reinvite control 
using address masks (the same idea as permit/deny), so watch for it in 
Mantis.
