That will never work.  Calling the Incomplete application means that the
dialplan will wait for more digits (and so the dialplan will restart).  You
need a more exact extension in the same context (or else the Incomplete app
needs to go into an included context).

We will never support this in 1.4, as this is a new feature, and new features
are not candidates for inclusion in that branch.  I'm sure you could backport
it for your own use, though.
