I understand that group-2 fax machines exchange some electronic information when a fax is sent from one machine to another. This information includes the phone number and company-name that is pre-programmed into a fax machine and normally appears in small print at the top of each fax page as printed by the receiving fax.
I believe this information might be known as "Station Identification" information or data.
I want to know if there are any fax machines or fax-software (running on a PC being used as a fax machine) that can block or drop incoming faxes based on this phone/company (station-ID) data?
Note: I am not talking about being able to drop/block a call based on caller ID. I want to be able to block/drop incoming fax calls based on the Station-ID info that can be (and if I'm not mistaken, must be) pre-programmed into fax machines by their owners before use. I understand that in some (or many) cases, a sending machine may not have any of this info programmed into their device, in which case I should still be able to block/drop such calls if they send null information.
Is there a name or term for this specific fax-blocking ability?
Are there any fax machines (specific brands/models) or PC fax software that can do this?
