header

The Oracle® Enterprise Session Border Controller also supports the Privacy type header. It modifies SIP headers that might reveal the user identity by:

• Stripping the Via header
• Replacing the Contact header
• Stripping Record-Route
• Removing the Privacy header
• Removing Proxy-Require option tag = privacy (if present)

In general, the B2BUA behavior of the Oracle® Enterprise Session Border Controller by default provides header privacy for all sessions.
