SIP re-INVITE Suppression

Some of the Interactive Voice Response (IVR) systems that support SIP frequently change the media transport address (IP address and/or port number) when switching between voice menus and/or prompts by sending a re-INVITE.

Often, no other parameters or properties of the session are changed in these re-INVITEs. The frequent re-INVITEs can create performance and capacity problems in other systems along the path of the IVR system and the caller’s User Agent.

You can configure the suppress-reinvite option on your Oracle® Enterprise Session Border Controller, allowing it to store the previous INVITE and its 200-OK response. Having this information allows the system to reply locally when a re-INVITE that changes only the media transport addresses is recieved.
