# Show call participants in contact list

Have the phone numbers of your team's contacts displayed directly in the app contact list

Should it makes sense for your team to be able check with whom a colleague or co-worker is currently talking to, you can add an additional system variable to show this information within the [PASCOM App](/en/user/pascom-app-userguide.md).

Doing so will enable each PASCOM App user to see the number and telephone book entry name (if stored) of the contact within the contact list.

{% hint style="info" %}
The display of the caller information with the PASCOM App contact list applies globally for every Desktop and Mobile App user and is not dependant on any assigned roles and user permissions.
{% endhint %}

## Set System Variables

In your PASCOM PBX WebUI, select **Appliance** > **System settings**. There is a variable with the parameter **sys.xmpp.properties.roster.shownumbers**. Set its value to **true**.\
Now save your changes.

## Example

The following example shows the effect of this system setting.

# 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/operations/clients/client-shownumbers.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.
