How do I block a phone number from calling in?
To block a caller from calling in you must first locate their customer account in "Customers > Manage". If they do not have a customer account, create a customer account with the said phone number.
Once created, locate the customer linked to the phone number and select the status inactive or blocked.
Tip: You can create a single customer called "Banned" and use the multi-phone number feature within the customer account to add to a list of blocked numbers.
