AW: Use of two Calling Party Number IEs

[Klaghofer Karl ICN SIB NL D1]

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).

Karl
