there is a "read" application that will use a file to prompt you with an audio file, ask for a certain number of digits and place then into a channel variable.  It's probably on the wiki

Hi,

I'm looking for a way to capture DTMF in the dialplan.  My goal is to
have a way for a user to enter an account number, pin code, etc.

I've seen some examples in javascript and/or perl, but would really
like to avoid using an "outside language".

Does FS have any kind of function to capture the DTMF.  (The format
for the javascript function looks great if there was something similar
in FS.  It allows you to set the number of digits, timeout, etc..)

Thanks,

-N
