We have several distributed 7960's working from behind nat boxes.
Config the phone itself with nat=yes (via the phone's keypad), and
in sip.conf use both nat=yes and qualify=5000. Have not had any
problems with MWI on these either.

Over the past 2+ years, I've seen various nat boxes that do not 
handle nat/pat correctly when two or more phones are behind the
same nat box. So, don't bet you're nat box is necessarily working
correctly on this.  The only way that I know of to actually verify
it is to use something like ethereal to inspect the packets, looking
specifically for the mwi packet, etc.
