Note quite what I meant to imply.....

The client _MAY_ present multiple aliases to the GK.  These aliases MAY or
_MAY-NOT_ match to a single device.  The question point is:

a) Does the GK return the first match?
b) If not, what happens on an exhaustive search that returns different
transport addresses?

In either case the GK can only return one address in the ACF. In either
case the EP cannot tell what happend from a protocol point of view.  There
may be a _big_ difference from a service point of view however.

It should definitely be a policy/configuration widget on the GK.  The
question in my mind is should the EP explicitly request one behavior or the
other? (similar to the GK-routing flag)
