When originally added it was only possible to terminate based on a
termination DTMF, so you'd know which DTMF key was used because no other
DTMF would stop. Afterwards a community member contributed a change[1]
to add an option to allow any DTMF key to terminate it, but the dialplan
variable stuff was not extended to make the knowledge of which DTMF was
used available.

Within the code f->subclass.integer is where the DTMF digit is. You'd
need to make a code change to set another dialplan variable which
contains it.

Re: [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

As far as I know the deb debug package just contains debugging symbols
(before these are stripped), you still need the normal asterisk packages
with the binaries. The last time I tried to debug with these packages it
was a waste of time since your not running a version with debugging
options. These debug packages show some extra info in gdb traces, but
lots of important stuff is still optimized away. 

If you need to debug install the source package and compile from there.
You might want to figure out how to manipulate the deb build rules to
include wanted flags, shouldn't be to hard but it has been a few years
for myself.
