# Configure a ringtone for critical alerts

Select a preferred ringtone for your critical notifications in the ITSM Mobile Agent application.

## Before you begin

Role required: admin

## Procedure

1.  Navigate to **All** > **System Definition** > **Script Includes**.

2.  Search for and select `CriticalPushPayloadBuilder` from the list of scripts.

    Verify that the selected `CriticalPushPayloadBuilder` script is in the **ITSM Mobile Agent** application scope.

3.  Open the `CriticalPushPayloadBuilder` record and edit the script with your preferred ringtone name:

    ```
    var CriticalPushPayloadBuilder = Class.create();
    CriticalPushPayloadBuilder.prototype = {
        initialize: function(currentGR, json, attributes) {
            this.currentGR = currentGR;
            this.json = json;
            this.attributes = attributes;
        },
        buildJSON: function() {
            if (this.attributes == null || this.attributes.isCritical == null || !(this.attributes.isCritical == "true"))
                return this.json;
            this.json["sncGoogleKeys"] = {
                "android": {
                    "priority": "high"
                },
                "priority": "high"
            };
            this.json["aps"]["sound"] = {
                "critical": 1,
                "name": "NotificationAlert-9-Short.caf",
                "volume": 1
            };
            return this.json;
        },
        type: 'CriticalPushPayloadBuilder'
    };
    ```
