Summary:                    IAX2 qualify problems between 1.6 and 1.4 boxes
Description: 
I have two boxes... one is running 1.4.22 and the other is running 1.6.0. 
Both are sending IAX2 POKEs to the other (as part of the qualification
process), but neither seems to be responding correctly to the other.  On
Tilghman's advice, I upgraded the 1.6.0 box to the 1.6.1 branch in SVN
(r150606), and am seeing the same thing.

I'm attaching two captures... the first is simply a packet capture of all
port 4569 traffic on the 1.6.1 box.  The second is the same thing, but with
both an "iax2 reload" and a "restart now" thrown in for good measure.

---------------------------------------------------------------------- 
Changing both boxes to say "auth=md5" instead of "auth=md5,rsa" fixed the
problem.  Anybody want to venture a guess as to why this would make any
difference on IAX2 qualifies?
