SIP INFO—RFC 2833 Conversion
The Oracle® Enterprise Session Border Controller can perform SIP INFO—RFC 2833 conversion. The Oracle® Enterprise Session Border Controller also provides a way for you to enable a dual conversion mode, where the Oracle® Enterprise Session Border Controller:
- Inserts telephone-event in the SDP offer
- Generates both RFC 2833 event packets and SIP INFO messages regardless of whether or not the SDP offer indicates RFC 2833
You can enable this feature either for SIP interfaces or session agents. The following apply:
- If the next hop SIP interface or session agent’s
rfc2833-mode is set to preferred, then the SD inserts RFC 2833 into the SDP offer/answer. This occurs regardless of whether:
- The original SDP on the opposite side of the call does not support RFC 2833
- The opposite side’s SIP interface or session agent is set to transparent mode
- If the next hop SIP interface or session agent is set to transparent, then the behavior of the
Oracle® Enterprise Session Border Controller depends on the previous hop.
- If the previous hop is a SIP interface or session agent configured for transparent mode, then the S Oracle® Enterprise Session Border Controllerdoes not perform any conversion.
- If the previous hop is a SIP interface or session agent configured for preferred mode, the Oracle® Enterprise Session Border Controller does not insert RFC-2833 into the SDP on the transparent side. It does, however, translate from RFC 2833 to SIP INFO if the originating endpoint supports RFC 2833.
