Objective
While making outbound calls from Twilio numbers, you may come across error message(s) like Account not authorized to call or receive warnings like 21215, 32205, 13227. These errors indicate that the call is being blocked due to Geo Permissions.
In these situations, before enabling Low-Risk or High-Risk permissions, it will be useful to check whether the destination number belongs to a Low-Risk Number Range or a High-Risk Toll Fraud Range.
