Configuring a PBX blacklist

The PBX blacklist object is a feature that allows you to reject calls based on the caller's number. Spam or unwanted callers can be added into this object and their call will be rejected automatically. Once you have logged into your customer portal click on the PBX tab. Then select the blacklist from the toolbox menu on the left, drag and drop the object onto the main configuration screen. Next, click on the settings icon. 




After that, you should enter a descriptive name, then click the add button and enter the caller ID's that you would like to blacklist, it is also possible to block international callers by using the full international dialling prefix. On top of this, you have the ability to block anonymous caller ID's, to enable this option, select the checkbox.




Finally, you should connect the blacklist object into your call flow. The blacklist object should be placed after the inbound number. From this point, all specified caller ID's in the blacklist will be blocked. Don't forget to apply the configuration.
