The requirement of TD-9 from Mr. Blin in Osaka was the support of two calling party numbers in H.323 (and NOT two Calling Party Number Information Elements) !
There was no agreement to intruduce a second Calling Party Number IE in H.225.0 (of course it is allowed due to the general H.323 statement that a GWY may pass on any Q.931 Information elements towards the LAN).
The agreement was that such a requirement of TD-9 from Osaka is already covered by H.323 anyway, since there are at least two fields already available (Calling Party Number IE and SourceAddress) to which e.g. two Calling Party Number IEs from the SCN could be mapped to or which may be used by an originating H.323 endpoint if there is the need to signal different calling party numbers.
The agreement was that the editor would add add some clarifying text (e.g. a sentence basically telling that Calling Party Number IE and SourceAddress may be used in the same SETUP message to carry different calling party numbers, if required).

Mr. Blin,
In Osaka, it was agreed as you proposed in TD-09 to add clarifying text to H.225.0 regarding the use of two calling party number IEs. Would the following clarification address this concern?
A note would be added to the Setup message IE table concerning use of the Calling Party Number IE that would state:
Multiple Calling Party Number IEs may be present in order to support, for example, the "Two Calling party number information elements delivery option" defined in Annex A/Q.951 or the interworking of H.323 and ISUP supplementary services as described in Annex C/H.246.
