Been covered before, You can't do that on an analog line. Problem comes
from where you are and what flash would be working on at that point. If
you flash asterisk and get dialtone again, you are getting the dialtone
from asterisk. At this point the only channel being worked is the one
you are on and flashing it won't help.

What you would need to do is get the other leg of the call to make the
flash. 

Of course if you where on a PRI link, you could do "hairpinning", "ect"
or "tromboning" and get the call taken back by the PSTN and transferred
to the new number.
