Removes the flow association from a phone number claimed to your Amazon Connect instance.

If the number is claimed to a traffic distribution group, and you are calling this API using an instance in the Amazon Web Services Region where the traffic distribution group was created, you can use either a full phone number ARN or UUID value for the PhoneNumberId URI request parameter. However, if the number is claimed to a traffic distribution group and you are calling this API using an instance in the alternate Amazon Web Services Region associated with the traffic distribution group, you must provide a full phone number ARN. If a UUID is provided in this scenario, you will receive a ResourceNotFoundException.
