Deny internal calls

General Help
1

Dear, does Custom Contexts module work for allow/deny internal calls among groups of extensions from the same LAN ???

For example, Group A = ext. 1000-1100, Group B = ext. 1200-1300 and Group C = ext. 1400-1500

So can Custom Contexts deny calls from Group A to Group B and from Group B to Group C ???

No routes, no trunks, just extensions…

Thanks a lot
