Source note · Wrong or missing caller ID on outbound calls
A US originating provider can give A-level attestation to a substituted or presentation number only if it has verified the customer's right to use that number. A number the enterprise does not hold with that provider, such as one ported elsewhere or belonging to a third party, is likely to be signed below A or to be screened.
