Block International Calls

[Frank Hoeben]

How do I prevent my users from calling international phone numbers?

CUCM 10.0 + Cisco H.323 gateway

Take into consideration that according to the NL numbering plan:

0 - external

00 - long distance

000 - International

So matching for 000 is preceded by a match for either 0 and 00.

I gather I'll have to do something with a route filter, but so far I haven't been able to create one that actually works.

Simply create just a RP to match 0 and 00 in your CUCM, you can even create one for 000 to block those calls so your users get a message.

I wasn't able to use a 000 route pattern, the callmanager seemed to like the match for 0 better.

However, I was able to figure out how to use route filters.

- created a 2nd 0.@ with a 2nd route partition (same calling search space).

- created two route filters: 1: no international, 2: international

- set the two filters on the respective route patterns

- enabled Forced Authorization Code on the international route pattern

This way only users that know the code can call international.
