I think that Francois's enhanced text will also help.

Subject: AW: Private telephone number in H.323v4
Francois, Paul, Bob and others,
Please refer to section 6.1.2 of the most recent H.323 Implementers Guide
(TD-031 PLEN) of the Brazil meeting. This IG section clarified previous
inconsistencies in H.323 sections, and compared to
H.225.0. I.e. the mentioned three H.323 sections have been updated for
clarification on PNP number usage.

Betreff: Private telephone number in H.323v4
I just realize a contradiction in H.323v4 and H.225.0v4 concerning the
encoding of "private telephone numbers" (i.e., the type we all use at work):
*         H.225.0v4 says that "Private telephone numbers" shall be encoded
in the UUIE as private numbers, and NOT in the Q.931 information elements
(Calling party IE, etc.). Let's call this the "Bob method". See Table
18/H.225.0 Note 1. 
*         H.323v4 says that the Q.931 information element is used for
"telephone numbers", and that the UUIE is used for things that are not
telephone numbers. Let's call this the "Glenn method". See H.323v4/
There is no conflict with both method for "public" telephone number, but
there is a conflict for "private" telephone numbers.
Which method is right, Bob's or Glenn's?
