  • Blacklist User Guide

    User Story
    An account wants to filter out unwanted calls before they ring. Common call types include robo-calls, international calls, and calls labeled Anonymous.

    This application
    Currently our blacklist configuration system is provided within the Callflows app.  As more customers are requesting this feature but do not need the other tools in callflows, we have separated it out and made it accessible to standard SmartPBX users. 

    • The two applications do use the same back end data. If you have already created blacklists in Callflows they should appear in the blacklist
    • listing for that account. 
    • The Blacklist app also allows you to enable or disable each list item from within the setup window; Callflows is a two-step process; you add numbers under blacklist and enable the blacklist under Account Settings. 

    Getting Started

    The blacklist app should be displayed in your Monster UI menu of applications.  If you do not see it, ask your administrator to enable it using the App Exchange.

    Creating Blacklists

    Your first entry to the app will indicate if you have no blacklists saved to your account.  
    You will see this:

    NOTE:  If you had entered blacklists in Callflows, you will see a list of them here. 

    Select the New Blacklist button and enter a Name.
    If you want the numbers to be deactivated immediately, you can toggle the “Enable on Creation” button.  Otherwise, it will save the information and  you can turn it on later.

    Enter your list of what numbers you want to block

    • The toggle to block Anonymous callers will block any CallerID that identifies as Anonymous.  This is in addition to any list you add for blocking specific numbers.
    • We recommend you create a unique blacklist just for Anonymous Callers as this is likely always on, and other lists may
    • To block international numbers make sure to include the full country code.
    • To block Canadian numbers, add +1 to the country code.  The rest of the number will be tracked and recognized as Canadian.

    Save your list! 
    Once your list is saved it will display on the home screen.  You can review it by clicking the gear next to your named list.  The new list will also appear in your Callflows app.

    Frequently Asked Questions

    Does this block outgoing calls to the same numbers also?
    No.  This application only blocks incoming calls.

    Can I enter a wildcard to mask for example, ALL phone calls from a certain region?

    If I update/add a blacklist entry to the Blacklist app, will it display in my Callflows app, and vice-versa?

    Why is there a separate Blacklist app?
    The blacklist app was developed to support SmartPBX users who do not have access to Callflows, and/or prefer a more simple approach to adding and editing a blacklist.  Its user interface matches a more friendly approach similar to the SmartPBX UI.

    Do anonymous calls also include calls that show all 0's as the caller ID?
