H.323 to SIP IWF Call

When the presentation indicator in the calling party IE is set to restricted, the INVITE’s From and Contact headers sent from to sipd will be modified according to RFC 3325. When the Oracle® Enterprise Session Border Controller receives calls initiated as H.323, it will recognize the caller’s presentation bits as defined in Q.931 and use that information to construct a SIP INVITE in accordance with the user’s indicated preference.

• Inclusion of a P-Asserted-Identity header in the INVITE, containing the calling party’s CPID and the Oracle® Enterprise Session Border Controller’s IP address, constructed as a SIP URI (same mechanism used to construct the From-URI today).
• Addition of a Privacy header with its value set to id. This addition indicates to the upstream proxies and gateways that the caller address is to be hidden.

The sipd will either proxy or strip these headers according to RFC 3325, depending on the SIP interface and SIP session agent configurations.
