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

[Patrick Mowry]

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,
