Hello Romaniuk,

PAID and privacy ID are used in the trusted domain only because it contain very important information about the network, user. The network entity passing this information is in trusted domain and if B2BUA is going to send to the trusted entity network then it should relayed this information to that entity. If this request is going to the non trusted entity then this information must be removed from the request before passing this to non trusted entity.

Hi Romaniuk,

if the destination for B2BUA is in trusted domain then simply the P-Asserted-ID heder should be relayed as such. This what our server does.

If a server within a trust zone sends "P_Asserted_ID" and "Privacy: id" to a B2BUA within that trust zone, does anyone know the correct procedure for the B2BUA when passing Privacy as a new request to another trusted member within the zone (or even back to the same originating server as part of third party call control)? Should the B2BUA still strip out the user information in the new request before passing it on to the trusted member (as if it is following RFC3325 and assuming that the server it is passing the requst to is always non-trusted), or should it just proxy the exact same PAI and Privacy headers it received and send it to the trusted server (since it is still within the trusted zone) and expect the new server to handle Privacy?
