What happens if a user tries to call a restricted number in outgoing call permissions?

When a user attempts to call a restricted number under a system that enforces outgoing call permissions, the call is denied. This denial is an intentional measure implemented by administrators to control costs, maintain compliance, or prevent access to certain types of phone numbers that may lead to toll fraud or unauthorized services.

By defining a set of numbers or categories of numbers that users are not allowed to call, the system effectively blocks any attempt to connect the call. This is particularly important in corporate environments where organizations want to manage their communication resources carefully and ensure that employees use their telephony systems responsibly.

In contrast, if the system allowed the call, it could result in unexpected charges or compromise the organization's policies. Forwarding the call or directing it to voicemail does not align with the purpose of restriction, which is to eliminate the possibility of completing the call at all. Thus, the correct outcome for calling a restricted number is indeed that the call is denied.
