# Endpoint Phone

This section will explain configuring phone call and SMS alerts for endpoints. The SMS and phone call alerting requires a subscription.

### Configure User Roles

Open the users page from the *Users* tab and add the same role that was configured on the alert to the users roles. For this example the `alert` role will be used. Once done click *Save*.

### Add Device

In the *User Devices* section select either *Phone (Call)* or *Phone (SMS)*. To receive both add the same phone number twice. Then enter the *Device name* and *Device phone number*. Once done click *Add Device*.

Then enable each alert level that this device will receive.

### Verify Phone Number

Each phone number must be verified before Pritunl will send SMS or phone calls to the number.

To verify the phone number call `206-202-9712` and press 1 when prompted. To remove the number verification call the same number and press 0 when prompted. The process is the same for configuring SMS or phone call alerts. Currently only US numbers are supported.

Once done click *Send Test Alert* to verify the device is receiving alerts.

An alert can also be tested by setting a very low threshold then waiting about 1 minute for the alert check to occur.

## 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 current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pritunl.com/kb/zero/endpoint/endpoint-phone.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
