Hi Russell,
    using branches/1.2 as of SVN rev 115572 today, I've had another VNAK 
storm incident; this was with the SVN-branch version talking to 1.2.24.

The 1.2.24 box:

May  9 13:02:04 DEBUG[2295] chan_iax2.c: Received VNAK: resending 
outstanding frames
[ several hundred per second ]

The SVN branch box:

May  9 13:02:04 DEBUG[17794] chan_iax2.c: Raw Hangup, 
src=0, dst=5
[ several hundred per second ]

No calls were going over the link, but 1.2.24 registers to svn-1.2, and 
both ends have qualify=yes.

Unfortunately, since I had to roll this back fast as fast can be, I 
didn't get full packet traces or iax debug output for this - if you 
can't make heads nor tails of this without such info, let me know and 
I'll have a go at breaking it again over the weekend.
