Private telephone number in H.323v4

Hi Bob,

I'm not sure I understand your point. 

The way I read it now:
*	H.323 says "Put a private number in the Q.931 IE"; and
*	H.225.0 says "Put a private number in the UUIE".

Which one is it? I think you are saying H.225.0 is right (I tend to agree
and so does Paul). We need to make sure everybody does (Glenn in
particular), and H.323 should be clarified, because I would assume most
people who read it will think they are supposed to put the IE in the Q.931
information element.
