SIP-ISUP Format Version Interworking

ISUP message can be carried in SIP messages through either a standard body or through a multipart MIME encoded body. While ANSI and ITU are the two major groups, but each contains many specific variants. To facilitate instances where two sides of a call use different versions, the Oracle® Enterprise Session Border Controller supports interworking between the following SIP ISUP formats: ANSI, ITU, ETSI-356 (an ITU variant), and GR-317 (an ANSI variant). To do so, the Oracle® Enterprise Session Border Controller can move, delete, and add parameters to various sections of the message.
