[cisco-voip] Site that has numbers that are same as 9.@ RoutePattern

[Lelio Fulgenzi]

OK - I see, your point, but I'm not sure I agree with the permit IP any any comparison. ;)

And we went through quite a bit testing and found that all the filters worked as promised and our classes of service each reflect their appropriate permissions. 

Unless of course, a bug appears (like that will ever happen). We had a time where although we filtered out international calling or something like that, when someone dialed 01 and waited, the system stripped the 1 and sent the 0 rather than sending an reorder tone as expected. Turned out, some guy added code some late Friday night for a production release to help some people in Europe and it had this unexpected affect. Had to wait until the 'overlap' system parameter was added to fix things.

  Exactly.. You add EVERYTHING in the NANP... and then
  you filter. As opposed to JUST adding what you want to
  permit. It opens a hole for toll fraud to the crafty
  user. Again to each his own, if you have not had any
  issues with it then run with it however it is against
  actually against Cisco "Best practices", which from a
  VARs perspective give you some sort a leg to stand on
  in the event of a problem.
