[cisco-voip] Is there any such thing as a null destination for an IOS dial-peer?

[Patrick Mowry]

Because I want them to be able to call every US domestic area code
except for 7.  So I assume it is easier to have a 91.......... pattern
accessable to everyone and then 7 more specific peers to block those
that are not allowed to be called than to build peers that match
everything else except the 7 not allowed.  And it is not a system wide
restriction.  I only need to block them for 6 people out of 50.  Their
job function is legally not allowed to call the area codes I need to
block.

Am I wrong in that dial-peer assessment?

Thanks again,

-Patrick

Rather than having a special COR to block calls why not just have COR  
setup so they don't match any dial-peers?  This will give them a fast  
busy and not tie up a channel.

Hello,

   We have a site using CallManager Express where some users are
restricted from calling certain area codes and directory assistance, but
not others.  So an example dial-peer I have to make it work is:

dial-peer voice 31 pots
  corlist outgoing Block-NC
  description ** NC Blocked dial-peer **
  destination-pattern 91252.......
  progress_ind setup enable 3
  progress_ind progress enable 8
  port 0/0/0:1
  forward-digits 0
  prefix ###

So a dn who's class of restriction contains Block-NC, matches this
dial-peer, we send only ### to the carrier so the users hears a reorder
tone (fast busy) instead of the call going through.  And this is what I
want to happen, except I would prefer not to take up a channel on the T1
circuit just to return a fast busy tone.  I thought of routing the call
to a CUE auto-attendant number that would only say you are not allowed
to call this area code then hang up.  But they did not want to use up a
Unity session for this either.

Since I only want to block these calls for some users and not all, does
anyone have a suggestion on a better way to do this?

Thanks,
