How can I make the Read() App wait a shorter time?

I’m using the Read() App in my Asterisk dialplan but i want to shorten the wait time of the App. I figure i’ll have to touch the source code but which file and what part?

thanks in advance

did you even try to read the wiki:

Read(variable[|filename][|maxdigits][|option][|attempts][|timeout])

voip-info.org/wiki/view/Asterisk+cmd+Read

set timeout to however long you want the app to read for…
