Route Header Removal

This section explains how to enable the Oracle® Enterprise Session Border Controller to disregard and strip all SIP Route headers. You set an option in a SIP interface configuration to strip all Route headers for SIP requests coming from this interface.

When the Oracle® Enterprise Session Border Controller with this option configured receives an INVITE from an interface, it removes the route headers. However, although it removes the headers, the Oracle® Enterprise Session Border Controller maintains backward compatibility with RFC 2543 nodes. To do so, it normalizes the request to an RFC 3261 loose routing form before it removes the headers.
