IWF Privacy Caller Privacy on Unsecure Networks

This feature enables bi-directional SIP/H.323 IWF support for CPID hiding by using the presentation indicators in the Calling Party Number information element for H.323 signaling, and RFC 3325-based privacy support for SIP signaling. It lets the Oracle® Enterprise Session Border Controller insert the P-Asserted-Identity and the Privacy header in the INVITE when the presentation indicator is set to restricted.

The presence, or absence, of P-Asserted-Identity and Privacy headers in the SIP INVITE informs the remote SIP proxy or endpoint to either block or advertise the CPID.
