Route Header Removal
This section explains how to enable the Oracle Communications 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 Communications 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 Communications 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.
