We'd love to help you with this! In terms of blocking numbers, there may be built-in features to do so, depending on the device in question. Look into that first, as it won't require adding any additional features. You can also check out our Call Protect, which enables you to block numbers as well. If you have any questions or concerns, feel free to ask us here!
