Do you mean to stop people dialing out, or dialling in?

I've never used the built-in blacklist stuff, but I'm not sure it supports 
wildcards.


For inbound stuff, just direct it to an extension that won't answer

exten => _0844.,1,Noop(Bah)
exten => _0844.,n,Hangup()

To stop people dialling out, you can do it the same way, or just use an if 
statemnt.

I do it based on other criteria, but it's all just code at the end of the 
day:

;       Access Level 1 check:
;               No 09x or 070x numbers (premium rate)

exten =>  s,n(checkLevel1),Noop(Macro-dialOut: Level 1 access check - All but 09 and 
070 ...)
exten =>  s,n,Set(DIGIT=${ARG1:1:1})
exten =>  s,n,GotoIf($[${DIGIT}=9]?noAccess)
exten =>  s,n,Set(DIGIT=${ARG1:1:2})
exten =>  s,n,GotoIf($[${DIGIT}=70]?noAccess:dialOutOK)

(this is inside a macro which is called when people dial 0 for an outside 
line - you are using 9 - how quaint ;-)
