Hi Asher,

Cisco isn't quite clear on how to flush the dtmf buffer. The most they
say on it, is in the IOS VXML Programming manual.
You can look here (and then look thru that entire ref manual):
http://www.cisco.com/en/US/docs/ios/voice/vxml/developer/guide/refgde1.html#wp1049201

As far as I can tell, there's no property that flushes the buffer. I use
a Digits element with BargeIn DISABLED and speak silence_.1_sec.wav and
set NoInput timeout to 10ms, MaxNoinputs to 1, MaxNomatches to 1,
MinDigits to 1, MaxDigits to 1. Then connect all the 3 exit states to
the next element in your callflow.

Thanks, Janine
