I've no idea what your UserEvent is doing other than adding more into the 
astdb, but you've not done anything to actually act on the astDB values.

All you're doing here is changing an astDB value on or off. Asterisk 
doesn't look at the astDB when it places a call - thats for you to do.

In your call-handling code, you need to read the astDB value then decided 
whether to dial the extension or not - and you're not doing this, or if 
you are you haven't put the code here.

So I have a rather large macro that handles internal calls and it has a 
section for DND:

; Check for Do Not Disturb

exten => s,n,Set(DND=${DB(${MACRO_EXTEN}/doNotDisturb)})
exten => s,n,GotoIf(${DND}?:doneDoNotDisturb)
exten => s,n,Wait(90)
exten => s,n,Hangup()
exten => s,n(doneDoNotDisturb),Noop(Carrying on after DO NOT DISTURB Check)


So in my case, if an extension has the "doNotDisturb" flag set 
(manipulated by code similar to your above), then it basically keeps the 
caller ringing for 90 seconds then hands up...
