# Practice Call Barring

### **What is it?**

Call Barring is a type of controlled phone censorship. It allows for blocking destinations, or certain specific numbers.

### **How to use it?**

You can install it in a PBX system with tools for block lists or destination blockers. The tools are specific to the PBX.

Call barring lets users bar or block certain types of calls, IP addresses, and destinations from being made to or from their phone. Some systems also let users block outbound calls to chosen destinations. Other options allow for only authorized business or employee IP addresses to make calls.

> [!NOTE]
> **NOTE:** Flowroute cannot prevent any inbound caller from reaching a Flowroute DID. Any type of **inbound call blocking must be done locally** on your phone system.
