outboundCallerIdNumberArn

The Amazon Resource Name (ARN) of the outbound caller ID number.

Only use the phone number ARN format that doesn't contain instance in the path, for example, arn:aws:connect:us-east-1:1234567890:phone-number/uuid . This is the same ARN format that is returned when you create a phone number using CloudFormation , or when you call the ListPhoneNumbersV2 API.
