Its my full "test" dialplan for now.  I do get fast busy as soon as I hit 8,
so that part works.

Fair enough, but that doesn't solve the original issue, but it makes my
kludge a bit better

Did I misread the Asterisk wiki pages, because I believed that when a
pattern was present, the pattern takes precedence over any "real"
extensions? (i.e. if I have both 1234 and _1XXX as extensions in a context)?


Thanks John, I appreciate all the info.
