Preferred 2883 Support

If one side of the call, or a SIP interface, or a session agent, is configured for preferred 2833, the Oracle® Enterprise Session Border Controller only generates and detects 2833 for endpoints if they signal support for 2833. The Oracle® Enterprise Session Border Controller will offer 2833 in the TCS SDP, even if the originating caller did not.

• When the Oracle® Enterprise Session Border Controller manages calls originating from a preferred source going to a preferred target, it:

  Performs 2833 translation for an endpoint when the originating side requests 2833 but the target does not negotiate 2833

  Allows 2833 to pass through if the originating side and target of the call are configured as preferred and negotiate 2833

• When the Oracle® Enterprise Session Border Controller manages calls originating from a preferred source going to a transparent target, it:

  Performs 2833 translation when the originating side requests 2833 but the target is configured as transparent and does not negotiate 2833.

  Allows 2833 to pass through if the originating side and the target of the call are configured as transparent and negotiate 2833. The Oracle® Enterprise Session Border Controller does not perform active translation because both ends support 2833.

  

If one SIP endpoint does not signal 2833 capability, but the other SIP or H.323 endpoints do, the Oracle® Enterprise Session Border Controller does not perform 2833 translation.
