Actually, this isn't quite correct.  With Asterisk, you can define both
the response timeout and the digit timeout (the one you specifically
mention above) using the TIMEOUT dialplan function.

As for having the system immediately dial out once an extension is
matched, it's really up to your dialplan.  Asterisk will connect to the
extension as soon as there's an *unambiguous* match.  Point an analog
phone at the context below, and I think you'll see what I'm trying to
say.  (Obviously SIP phones are different than analog, in that they 
usually send the entire dialed number at once -- if you're using a SIP
phone, you may be encountering a dial timeout on your phone, and not in

exten => 12,1,SayNumber(12)

exten => 2,1,SayNumber(2)
