Read() — Reads DTMF digits from the caller and assigns the result to a variable
Reads a #-terminated
string of digits from the user in to the given
variable.
Other arguments include:
filename
Specifies the file to play before reading digits.

argument is specified, the application stops reading after
maxdigits have been entered (without
requiring the user to press the # key). Defaults to 0 (no limit, wait for the user to press
the # key). Any value below
0 means the same. The maximum
accepted value is 255.

iInterpret the filename as an indication tone setting
from indications.conf.
nRead digits even if the line has not been answered.

many attempts will be made in the event that no data is
entered.
timeout
If greater than 0, that
value will override the default timeout.
