Cisco CUCM 7.1: Is there a way to require a PIN to reach certain long distance numbers?

I would like to permit only users with a known PIN to be able to dial known heavy fraud countries like Turks and Caicos etc. Is there any means to effect this in Cisco Unified Communications Manager? My other option would be to use partitions and calling search spaces and limit access to certain phones or DNs. But PIN access would be even better.

create route patterns that specifically match the countries dialing pattern. ie 9.1649XXXXXXX. On the route pattern, select the checkbox 'Require Forced Authorization Code', set the authorization level to 5 (as an example). Under Call Routing, create a Forced Authorization Code with a matching or higher level access.

my preferred method is to create a route filter with all the area codes for non US area codes - or at least the higher offending ones. Create a 9.@ route pattern and apply the route filter and assign the authorization code.
This method allows a single route pattern to match all the offending numbers without having to create a route pattern for each country you want to block/restrict access.

Say - an add on question if I may.. I already have a route pattern 9.@ for my general outbound calls. Would I just create another 9.@ route pattern only with the filter and force auth and position it above the general purpose 9.@?

have you ever done device/line calling search spaces? the original 9.@ would go on the device(phone), the filtered one would go on the line (DN)

I wear many hats and haven't looked and haven't looked at this in a while. But yes indeed - I get what you're saying. Thank you!

I added the new Route Pattern 9@ with Partition FILTER-STND and filter Abuse (all the bad country codes and area codes) and added Require Forced Authorization Code level 11 and it is set to ROUTE THIS PATTERN.  The DN and Line for my phone use CSS LINE-UNRESTRICTED which has but one partition in it FILTER-STND. Alas the calls seem to be getting out unfettered. I did see a brief flash that perhaps I need to reset the gateways. Could that be it?

My earlier success was when I added a Route Pattern to a specific number and added it to the partitions in the CSS of my device. So if push comes to shove I guess I could add 30, 40 route patterns with BAT. But I really would rather use the Filter method.

Ah - I was farther along than I thought. If I add a 1 to the front of the number then I get the authorization prompt. But if I dial the Turks and Caicos number without the 1, e.g. 649-941-8XXX then the number just passes on its way to the PSTN. So it has something to do with the 9@ and the NANP. In the worst case I should be able to wild card this and not specify NANP.

649 without the 1 is not a legitimate number outside the 649 area. Either your carrier (like with cell phones) or your dial plan/gateway are adding a 1.
