Identical Inband with Signaling DTMF Transfer Exception

Endpoints may send signaling-based DTMF indication (SIP INFO) to the Oracle® Enterprise Session Border Controller at any time. Most of the time they are passed through the Oracle® Enterprise Session Border Controller unchanged. You can enable an exception to this behavior forcing signaling messages to either RFC 2833 or DTMF audio tones depending on the call’s DTMF transfer mode. The two parameters to enable their respective exceptions are located in the media manager configuration.

Note:

These behavior exceptions are only applicable when both sides of the call support and prefer the same DTMF transfer mode.
