### Configure Static Tabs with URL Parameters in MS Teams Manifest.json

Source: https://github.com/webtrit/webtrit_docs/blob/main/integrations/ms-teams/index.md

This snippet demonstrates how to configure the `staticTabs` section within the manifest.json file to include URL parameters in the `contentUrl` and `websiteUrl` fields. This is shown as a solution to pass special parameters, potentially to control application behavior like disabling a navigation drawer.

```JSON
    "staticTabs": [
        {
            "entityId": "index",
            "name": "Dialer",
            "contentUrl": "dailer.com/home?mode=mst",
            "websiteUrl": "dailer.com/home?mode=mst",
            "scopes": [
                "personal"
            ]
        },
        {
            "entityId": "about",
            "scopes": [
                "personal"
            ]
        }
    ],
```

Source: https://github.com/webtrit/webtrit_docs/blob/main/signaling/websocket_subprotocol.md

);
```

### Simplest Handshake Keepalive Message (JSON)

Source: https://github.com/webtrit/webtrit_docs/blob/main/signaling/handshake/keepalive.md

This is the most basic form of the handshake keepalive message, containing only the required 'handshake' field with the value 'keepalive'.

```json
{
  "handshake": "keepalive"
}
```

--------------------------------

### Hangup Call Request (JSON)

Source: https://github.com/webtrit/webtrit_docs/blob/main/signaling/requests/call/hangup.md

This JSON object represents a request to hang up a specific call identified by `call_id` on a particular `line`. The `transaction` field is used to correlate the request with subsequent events.

```json
{
  "request": "hangup",
  "transaction": "transaction-1",
  "line": 0,
  "call_id": "qwertyuiopasdfghjklzxcvbnm"
}
```
