Source note · Wrong or missing caller ID on outbound calls
Microsoft's disputed statement: according to the Set-CsOnlinePSTNGateway reference, setting ForwardPai to $true 'will render the from header anonymous', citing RFC 5379 and RFC 3325, whereas the Teams caller ID article says that with ForwardPai true the From header still carries the substitute number and CNAM. Neither page says which behavior applies to which calls.
