asterisk users - Nov 2010 - DAHDI / dial in / overlap digits / timeout

Hi,

our Asterisk is connected to an E1 port. So we are using the 
DAHDI-Driver. Please , how do I tell the driver/Asterisk to wait for 
overlap digits for in-calls? I found the option "overlapdial=yes" but
I
did not try yet. Is that "my" option? Is there any option for setting
an
timeout?
