H.225 white draft - more

[Paul E. Jones]

Terry,

Following that logic, I believe it makes sense to have the desired/needed
features in the GRQ.  That way, if the GK does not support the needed
features, it could chose to not respond or send a GRJ message.  The idea, of
course, would to put the endpoint into a zone with a GK that supports the
needed features.
