[SIPForum-discussion] RPID and PAI difference

[Nitin Kapoor]

Hi,

Here it is...

PAI

The P-Asserted-Identity header field is used among trusted SIP entities to
carry the identity of a user sending a SIP message as it was
verified by authentication. A proxy server which handles a message can,
after authenticating the originating user can insert such a
P-Asserted-Identity header field into the message and forward it to other
trusted proxies. A proxy that is about to forward a message to a proxy
server or UA that it does not trust MUST remove all the P-Asserted-Identity
header field values if the user requested that this information be kept
private.

Remote Party ID:

The SIP Remote-Party-ID header identifies the calling party and includes
user, party, screen and privacy headers that specify how a call is presented
and screened. The new header contains a url and an optional display name
that identifies a user. A valid Remote-Party-ID header may be either a sip
url or a tell url.

Thanks,
Nitin Kapoor
