HPBX makes it easy for you to block certain types of calls. In recent years this has been quite important for 2 reasons. It stops employees from making calls to places they don’t need to call as well as stopping hackers from defrauding your system.
First you need to login to HPBX and go to features then classes of service.
In this tutorial it will show you how to stop international calls for a particular extension. Click on the new button to create a new class of service.
I have created a new class of service called “No International”. Now click the save button. By default we will allow all internal and external calls. After saving the function click return to the class of service functions and then click into the No International function.
Now you are in the function you want to create an external exception to the normal rules. Click on the new button to create an exception.
Go to the phone with the selected extension and make sure that it cannot dial any international calls.
