**Blocklist** rejects calls from numbers you list. A blocked caller hears a busy tone and the call ends. Other calls pass through to the next object.

This blocklist only applies where you place it in the call flow. To block numbers for your whole PBX, use the [Global blocklist](https://kb.voipcloud.online/au/pbx/settings/global-blocklist/).

## Add it to your call flow

1. Drag **Blocklist** from the **Protection** group onto the canvas and click the gear icon.
2. Enter a **Name**.
3. Click **Add number** for each number to block, with an optional **Comment**. To block consecutive numbers, click **Block a phone number range** in the same window and enter the **Start of range** and **End of range** in international format with the country code, for example 61399998800 to 61399998810. You can block up to 100 numbers at a time.
4. Turn on **Block anonymous calls** if needed.
5. Click **Save**, connect it right after the [Inbound number](https://kb.voipcloud.online/au/pbx/receive-calls/inbound-number/), and click **Apply configuration**.
