[Asterisk-Users] Attack dialing

[Matt]

Ok.. here is another pet peeve i have.. that maybe someone can answer...
When I do a call file.
How can I make the call be transfered to the second party BEFORE the
first party picks up?  In other words.. right now if it's busy it will
keep trying.. however if it's ringing... it waits until PARTY 1 picks
up and THEN transfers the call to party 2... how can I transfer to
party 2 as soon as I start getting ringing to party 1?
