Example 2

In this example RFC 2833 telephone-event is not supported on the egress side of the call, but DTMF audio tones are. If the Oracle® Enterprise Session Border Controller receives an RFC 2833 message, it is converted to DTMF audio tones. When the Oracle® Enterprise Session Border Controller forwards DTMF audio tones to the SDP answerer, it also creates and forwards a corresponding SIP INFO message toward the target.
