Juha,
I believe this is handled in RFC3325: Private Extensions to the Session
Initiation Protocol (SIP) for Asserted Identity within Trusted Networks,
RFC4497: Interworking between the Session Initiation Protocol (SIP) and
QSIG, and RFC3323: A Privacy Mechanism for the Session Initiation
Protocol (SIP) which is the "Privacy" header.
RFC4497 section 9 says:
"A gateway MAY implement the P-Asserted-Identity header in accordance
with [14]. If a gateway implements the P-Asserted-Identity header,
it SHALL also implement the Privacy header in accordance with [13].
If a gateway does not implement the P-Asserted-Identity header, it
MAY implement the Privacy header."
[13] is RFC3323
[14] is RFC3325

i don't have good enough net access to check, but does pai header also
support controlling of display of calling number like rpid does with its
privacy parameter? if not, then it cannot be used as a replacement of
rpid header
