Global Call Reference Value

[Logan Modahala]

Paul,

That's yet another inconsistency. If you use Global CRV in Facility for
"multipleCalls" the only way you can
do is using "empty" but that is disallowed and hence Facility-UUIE must
be used. In which case we cannot include a "CallIdentifier". But
CallIdentifier is NOT OPTIONAL. Same with Status and Status Inquire as
well with "multipleCalls".

My take is that "empty" makes sense there but I know others don't like
"empty".  Otherwise, we need to come up with a "DUMMY Call Identifier"
for thsi purpose.
