asterisk users - Apr 2004 - application Directory

Let's say an unsuspecting soul accidently selects the Directory option 
from an Auto Attendant (CVS circa 3/22). Three questions:

1) How do they escape if they didn't mean to go there in the first 
place (without having to hang up...)?

	exten => 1,1,Directory(vertex)
	exten => 1,2,Goto(s,200)

2) Why is there a five second pause before the directory instructions 
start?

3) Why no option for first name (without recording your own custom 
message and reversing names in voicemail.conf)?

Thanks,
Ryan
