[asterisk-users] Losing first DTMF digit (with ASR)

Yeah, but with switchtype=qsig, though that difference isn't likely
relevant here.

No.  There are plenty of others, starting with an Answer(200).  Then
a whole bunch of Speech* applications to load grammar and such along
with some Sets.

No. But if I do that, I'll INCREASE the chance of losing DTMF since people
may start dialing before the SpeechBackground (though, as I said, it isn't
this problem since I've seen it when I know I've waited).  Also, this is
intermittent so I want to minimize the number of experiments since it'll be
very hard to see if I'm actually improving something.

None since DTMF is sent, not speech.  It just shows Add, activate, delete,
and close.  I don't know that I've actually seen a log when the first DTMF
digit is missed (too hard to reproduce), so I don't know if it's different.
