asterisk users - Dec 2004 - Macro(dundi-dundi-test, ${ENTEN}) to return +101 on lookup failure ?

I'm looking at finding a way for my Macro(dundi-dundi-test,${ENTEN})
when I dial out on the dundi-test network to return a +101 to my
[dundi-test-out] context, if the number being dialed on the dundi-test
network does not exist, then I will route the call out using my pstn
or voip connection i have.  I have a feeling it will have to be the
switch => DUNDi/dundi-test that will have to return the +101.

Also currently, using CVS HEAD of asterisk and dundi, when dialing a
number on dundi-test my asterisk crashes with a clean crash and must
be re-started manually.  Any ideas?
