[asterisk-users] Simple speech recognition for driving IVR - "press or say one".

[Jonathan H]

Hang on, all of the fiddling in this thread seems remarkably
over-complicating what should be an incredibly simple task.

We know that a DTMF keypress interrupted the recording. We also know
that app_record.c knows which keypress it was from

* \param dtmf_integer the integer value of the DTMF key received

as in

static enum dtmf_response record_dtmf_response(struct ast_channel
*chan, struct ast_flags *flags, int dtmf_integer, int terminator)

For reasons which have me scratching my head, app_record turns a
useful DTMF value into a rather meaningless "DTMF" in the
RECORD_STATUS variable.

But SOMETHING must be floating around in Asterisk for app_record.c to
know what number was pushed. If I'm using RFC2833, is there ANY way of
getting that last keypress.

In other words: "The user pressed a number, recording stopped, now
what was that number?" - WITHOUT rewriting and recompiling a core
application or doing any complex workaround?

Thanks
