# Blocklist - Blocking Phone Numbers

Use the PASCOM blocklist to efficiently manage and block unwanted calls.

Recurring advertising calls, spam, or other disruptive callers interrupt workflows and tie up valuable resources. With the **Blocked numbers** feature, administrators can centrally manage unwanted phone numbers and add them to a blocklist.

## Block New Phone Number

Navigate to the blocked numbers overview in the admin dashboard to add and manage new block entries.

1. Navigate to **Trunks** > **Blocked numbers** in the admin dashboard.
2. Click **Add**.
3. Enter the details of the phone number to be blocked into the form.
4. Click **Save & close** to save the entry.

### Options and Settings

The following options are available for each block entry:

| Option         | Description                                                                                                                                                                           |
| -------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Name**       | A custom name for better management and overview (used for display purposes only).                                                                                                    |
| **Number**     | The phone number to block. The input is currently not validated to allow flexibility for different formats. However, please note the required phone number format (see notice below). |
| **Enabled**    | Use this switch to activate or deactivate the entry at any time. This allows you to quickly test or temporarily disable blocks.                                                       |
| **Match mode** | Determines the matching method for the block (see details below).                                                                                                                     |

{% hint style="warning" %}
**Important phone number format:**

* The phone number **must start with 0** (e.g., `0049991123456` or `0991123456`).
* Do **not include special characters**. Do not use `+` (e.g., use `0049...` instead of `+49...`) and do not use separators like `/` or `-` (e.g., do not write `0991/123456` or `0991-123456`).
  {% endhint %}

### Select Match Mode

Administrators can choose between two blocking methods:

* **Exact:** Blocks exactly the entered phone number.
* **Begins with:** Blocks all incoming calls where the phone number starts with the entered sequence of digits. This is especially useful for recurring spam waves originating from the same range or specific countries (e.g., by entering a country code such as `0044` for the United Kingdom).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.pascom.net/en/setup/pascom-trunk/blocklist.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
