Restrict extension to intern and local calls

[Renoeka (Suriname)]

hi,

I want to ask if it is possible to restrict extension from calling to international numbers?
If yes, how?
I have seen that the module class of service can be used. But this has to be bought. I want to use a module or way which is free.

But how? should the extensions be placed where is written caller ID in the tab of dial pattern?

[dicko]
