I handle my DIDs with a macro.  A DBget fetches a target for Goto.  If
the key doesn't exist, it jumps to a hangup macro that can either drop
with PRI_CAUSE=1 (invalid) or play Zapateller and ss-noservice.gsm
twice, then hang up with PRI_CAUSE=31, depending on how you want it to
work.  Of course, don't answer first, and if you do Playback(),
remember the noanswer option and play a silence/1 first..

Some samples from database show (numbers changed to protect the
guilty, and I receive full 10 digits)
/DID/9001235900                                   : mainmenu|s
/DID/9001235904                                   : 104                      
/DID/9001235917                                   : 117                      
/DID/9001235939                                   : 139                      
/DID/9001235942                                   : 142                      
/DID/9001235970                                   : 170                      
/DID/9001235949                                   : disa|s

[from-pstn]
exten => _NXXNXXXXXX,1,Macro(did,${EXTEN});

[macro-did]
exten => s,1,DBget(target=DID/${ARG1})
exten => s,2,Goto(${target},1); db should not include the priority
exten => s,102,SetVar(PRI_CAUSE=1); tells telco to play discon message
exten => s,103,Hangup; 
; target can be simply an extension: my stdexten does more DBget to find channel
exten => _1XX,1,Macro(stdexten,${EXTEN})
