until at least a consensus is formed on the semantics of multiple aliases in
ARQ's destinationInfo, an EP had better send a single alias if the user has
any hope of predictable--not necessarily deterministic--behavior. As with many
things H.323, _caveat transmittor_.

Note quite what I meant to imply.....
The client _MAY_ present multiple aliases to the GK. These aliases
_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
In either case the GK can only return one address in the ACF. In
case the EP cannot tell what happend from a protocol point of view.
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
other? (similar to the GK-routing flag)
