# eCall services

eCall is a system widely used in Switzerland for automatically sending SMS and voice messages. 

## How it works

eCall sends SMS and voice messages by email. 

{% hint style="warning" %}
eCall is a paid service!
{% endhint %}

## Activate eCall in eliona

Proceed as follows to activate the eCall function in eliona

{% @supademo/embed demoId="clm08sqoj4o4u1s194myacnrp" url="<https://app.supademo.com/demo/clm08sqoj4o4u1s194myacnrp>" fullWidth="true" %}

### Alarm grouping

Alarms can also be grouped here, just like with other notification providers.&#x20;

{% content-ref url="/pages/e6e1b849067aba2b868e1a38313521a652c84a2c" %}
[Group escalations](/collection/english-v14/documentation/alarms-rules-and-escalations/escalations/group-escalations.md)
{% endcontent-ref %}

## Specify phone number

Eliona needs to know which phone number the SMS or voice message should be sent to.

When creating a user, a phone number can already be stored.&#x20;

You can add the contact details later: [Add a user’s contact details](broken://pages/79b9dc1aa0c62ade6129d7e4e7299b71879b5e90)&#x20;

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

```
GET https://docs.buildings.ability.abb/collection/english-v14/documentation/alarms-rules-and-escalations/escalations/notification-provider/ecall-services.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.
