Both UAs are cisco 7960's (POS3-04-3-00).  I don't see why either would 
time out.  It's only 15 seconds for fr_inv_timer.  I also just tested 
with another singly-registered user and the error still happens so it's 
not a multiple dset thing.

Part of the problem is since asterisk is running on localhost I won't be 
able to get captures for that.  I suppose I could move it to another 
machine just to help get some tcpdumps.  I'll do that and send along.

I'll be happy to test it, but you need one of the canned IVR messages to 
be "Weasels have eaten our phone system" before you'll see a mass exodus 
from asterisk to sems;-)
