That was my interpretation as well. Nevertheless, the behaviour I witnessed from Sonus is:
* If 'Privacy: none' is present, RPID URI user part is not taken into account as calling party number, but only From URI. * If 'Privacy' header is removed entirely, RPID URI user part is used as the calling number. I did not try any other values of the 'Privacy' header. I cannot find any RFC or draft that makes explicit the connection between the 'Privacy' header and the concept of privacy as rendered in RPID. Yet, that's the only explanation I could come up with.
